osmo-bts currently does not generate a measurement report in case the
SACCH of the related traffic channel is lost. This is a problem because
the moment when reception gets bad measurmenet reporting is crucial to
carry out handover decisions effectively.
The presence of a SACCH block controls the conclusion of the measurement
interval and the sending of the RSL measurement report. The latter one
not only requires a measurmenet indication, it also requires a fully
intact SACCH block.
Lets use the NOPE / IDLE indications from V1 of the TRXD protocol to
ensure a SACCH block is always reported up to l1sap.c. In cases where
the SACCH is bad, trigger the sending of the RSL measurement report
manually without attaching the measurmenet data from the MS (which we do
not have in this case)

Let's drop it instead of having code duplication from common code in a
lower layer, and maintain only the one in l1sap for all BTS models.
As a result, osmo-bts-trx loses feature BTS_FEAT_MS_PWR_CTRL_DSP and
will only be able to use "ms-power-control osmo" in VTY, which will be
enabled by default (meaning: change of behavior, now MS Power Control is
enabled by default in osmo-bts-trx and can only by disabled by BSC).
Old bts-trx specific VTY command "(no) osmotrx ms-power-loop" is marked
as deprecated but still working for more usual case (1 TRX configured)
to avoid breaking backward compatibility.
TA low level loop is still kept in loops.c and will be moved to l1sap at
some point too.

Since there can be multiple PDCH channels configured on different
timeslots, different TRXes, and BTSes, the PTCCH/U handling code
in OsmoPCU needs to know the exact origin of a given RACH.ind.
Otherwise, it is not known which subscriber originated a given
PTCCH/U indication, and hence it is impossible to send PTCCH/D
Timing Advance notification properly.
Fortunately, we can extend the RACH.ind message without even
bumping the protocol version, because every single PDU has a
fixed size defined by the largest message - INFO.ind. In case
if the actual message payload is smaller, the rest is filled
with a constant padding byte (0x00).
Older versions of OsmoPCU will consider the new fields as padding,
while the messages from older OsmoBTS versions will always have
both fields set to 0x00. Since C0/TS0 cannot be configured to
PDCH, this can be easily detected on the other end.

calculations
Use instead the received MS Power currently in use by the MS matching
the measured signal. This way there's no need to wait for the MS to
reach the announced MS power level or add checks in case the MS doesn't
support that specific power level. Furthermore, more fine grained
announced power level value can be obtained faster due to more input
iterations not being dropped while waiting.
osmo-bts-trx specific algo was not following this approach and using
announced MS power instead because it's wowrking at a lower level and
henche was not using the transmitted MS Power level value by the MS as
input for the calculation.
The "if (diff < 2 && diff > -2))" condition is dropped since equal
signal strength may still result in a different MS power level announced
(the one currently used by the MS during tx of last SACCH block).

Each logical channel can now optionally have an additional handler,
that will be called when a NOPE / IDLE indication is received from
the transceiver. The aim of that handler is to keep the logical
channel state updated in case if one or more Uplink bursts are lost.

It indicates whether BTS model supports managing an MS Power Control
Loop over HW/DSP instead of using the software based osmocom algorithm
present in osmo-bts.
osmo-bts-trx own loop implementation is considered to be a "DSP/HW" one
since it acts on lower layers and interferes with osmocom algorithm
since it controls the same end variable "lchan->ms_power_ctrl.current",
this way we make sure both aren't enabled at the same time.
Old behavior in kept: if common upper-layer algo is not enabled
explicitly in VTY (ms-power-control osmo) and bts-trx specific lower
layer algo is neither enabled (osmotrx ms-power-loop <xyz>), then no
power control is done at all.

Thies field is used to store and retrieve whether MS power needs to be
calculated and updated by osmo-bts software or autonomously by lower
layers. Previous name was not clear
and may have been understood as indicating whether MS Power Control loop
is done or not in general, and the responsible for that is located under
lchan's ms_power_ctrl.fixed.

Before this patch, if due to whatever reason the TRX started fine (RSP
POWERON 0) and sockets were created but no CLOCK IND was ever received
by the BTS, it wouldn't notice since the timerfd timeouts
(bts_shutdown("no clock")) are only checked after the first CLOCK IND is
sent by the TRX.
As a result, the BTS would be kept on forever saying everything is fine
but it would be sending no DL burst at all to the TRX (tested with a
modfied osmo-trx dropping clock indication).
With this patch, new APIs are added to indicate the scheduler_trx code
the timeframes where clock ind are expected (between RSP POWERON 0 and
RSP POWEROFF 0); if TRX sends clock indications out of that timeframe,
BTs lower layers will drop them (controlled by "powered" bool).
Hence, the scheduler_trx can now place a timeout (reusing same timerfd
because its new use is exclusive in time with its other previous use)
when it is told that CLOCK IND should start appearing, and if none
arrives in considerable time, then the BTS can be shut down to notify
the rest of the network.

Add a new common L1 SAPI enum, to unify all the BTS specific SAPIs.
Translate to this enum, and set the context for uplink messages in
each BTS specific implementation.
Set the context for downlink messages in the common l1sap code, by
converting the osmo_phsap_prim back to the SAPI value (mostly looking at
chan_nr). The new functions for doing this conversion,
get_common_sapi_by_trx_prim() and get_common_sapi_ph_data(), are based
on the existing to_gsmtap() and gsmtap_ph_data() functions.
Note that we can't set the uplink SAPI context in the common code,
because then we can't set it as early as possible. In this patch, the
SAPI context is set for the PHYs where the SAPI is readily available.
With additional conversion from the RSL channel, the SAPI context could
be set for osmo-bts-trx in a follow up patch.

Use of variables in each code is confusing and mixing configuration with
POWERON/POWEROFF state (which is at least per phy inst and not per TRX,
since those commands are only expected on the 1st phy inst).
* field "poweron" becomes "enabled", and is used as an indicator for
actions to take during TRX provisioning (hether to power it on and
configure it or to power it off).
* poweron/poweroff state becomes "powered", and it is shared by all trx
in same phy_link, and is updated only after confirmation by TRX.
* poweron_set becomes poweronoff_set (because it's used by both POWERON
and POWEROFF), and becomes shared by all trx in same phy_link, since
those CMDs are usually sent by first phy instance of the link (the first
trx).

Currently there's bts-virtual specific fields in gsm_bts which is not used
by other models and are always allocated.
An alternative would be having a union with different structs inside,
one per model, but since we already have the bts_model abstraction, in this
case it makes more sense to use that abstraction instead of filling code
with preprocessor ifdefs to guard against non-defined types, etc.
Existing model specific data is moved there.
This new infra will be user further in forthcoming commits.

According to 3GPP TS 45.010, section 5.6.2, for packet-switched
channels the BTS shall monitor the delay of the Access Bursts
sent by the MS on PTCCH and respond with timing advance values
for all MS performing the procedure on that PDCH.
According to 3GPP TS 45.002, section 3.3.4.2, PTCCH (Packet Timing
advance control channel) is a packet dedicated channel, that is
used for continuous Timing Advance control (mentioned above).
There are two sub-types of that logical channel:
- PTCCH/U (Uplink): used to transmit random Access Bursts
to allow estimation of the Timing Advance for one MS in
packet transfer mode.
- PTCCH/D (Downlink): used by the network to transmit
Timing Advance updates for several MS.
As per 3GPP TS 45.003, section 5.2, the coding scheme used for
PTCCH/U is the same as for PRACH as specified in subclause 5.3,
while the coding scheme used for PTCCH/D is the same as for
CS-1 as specified in subclause 5.1.1.
The way we used to handle both PTCCH/U and PTCCH/D is absolutely
wrong - they have nothing to do with xCCH coding. Instead, we
need to use tx_pdtch_fn() for Downlink and rx_rach_fn() for Uplink.
In l1sap_ph_rach_ind() we need to check if an Access Burst was
received on PTCCH/U and forward it to OsmoPCU with proper SAPI
value (PCU_IF_SAPI_PTCCH). To be able to specify a SAPI, a new
parameter is introduced to pcu_tx_rach_ind().

All MS/UE must be notified of ETWS Primary Notifiations.
Depending on their state, the notification goes different paths:
* CS dedicated mode: BSC sends it as L3 message over LAPDm / DCCH
* CS/PS idle mode: BTS sends paging messages on PCH
* PS TBF active: PCU send Packet Application Info
This enables the last of the three methods by passing any
ETWS Primary Notifications received over RSL via the PCU socket into
the PCU.

The ETWS (Earthquake and Tsunami Warning System) uses a so-called
ETWS Primary Notification which is sent
* to phones in dedicated mode (via DCCH from the BSC)
* to phones in idle mode (via P1 Rest Octets on PCH/CCCH)
This patch implements the second part of the functionality, i.e.
transmitting the related ETWS Primary Notification via PCH. As
3GPP doesn't specify how this is communicated over Abis, we use
a new, vendor-specific RSL message type.

Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However,
definition in C file doesn't contain "(void)", which means number of
parameters is undefined and thus compiler doesn't complain. Let's remove
parameters from all callers before enforcing "(void)" on it.
API osmo_stats_vty_add_cmds never had a param list but has seem problem
(no "void"), so some users decided to pass a parameter to it.

This command allows setting a maximum TRXD format version to negotiate
with TRX. osmo-bts-trx will hence end up using that version if supported
by TRX, or a lower one otherwise (or fail if TRX doesn't support any of
them).
Since now the maximum version can be 0, avoid going through SETFORMAT
negotiation in that case, since 0 is the default version. This way we
keep backward compatibility with TRX implementations that exit upon
receival of unknown commands (such as SC5 current one).
The VTY command is located in the "phy" node instead of the "phy
instance" node because instances of same phy are expected to use same
host with same implementation, so TRXD version to use should be the same
for both.

The radio link quality is defined by C/I (Carrier-to-Interference
ratio), which is computed from the training sequence of each
received burst, by comparing the "ideal" training sequence with
the actual (received) one.
Link quality measurements are used by L1SAP to filter out "ghost"
Access Bursts, and by the link quality adaptation algorithms. One
can define minimum link quality values using the VTY interface.
On the VTY interface we expect integer C/I values in centiBels
(cB, 10e-2 B), while the internal structures are using float
values in deciBels (dB, 10e-1 B). Some PHYs (sysmo, octphy,
oc2g, and litecell15) expose C/I measurements in deciBels,
while on the L1SAP interface we finally send then in centiBels.
Let's avoid this confusion and stick to a single format, that
will be used by the internal logic of OsmoBTS - integer values
(int16_t) in centiBels. This will give us the range of:
-32768 .. 32767 centiBels, or
-3276.8 .. 3276.7 deciBels,
which is certainly sufficient.

C/I (Carrier-to-Interference ratio) is a value in cB (centiBels),
computed from the training sequence of each received burst,
by comparing the "ideal" training sequence with the actual one.
So far, there was no way to expose more measurements from OsmoTRX,
excluding both RSSI and ToA. Since the new version of TRXD header,
we can receive C/I indications and send the averaged (per 4 bursts)
values to OsmoPCU (as a part of PCUIF_DATA.ind).
Please note that we also need to attach C/I measurements
to the following L1SAP primitives:
- PRIM_PH_RACH.ind,
- PRIM_PH_DATA.ind,
- PRIM_TCH.ind,
but this will be done in the follow up changes.

The new version adds the following fields to the TRX2L1 message,
keeping the L12TRX message unchanged:
+------+-----+-----+-----+--------------------+
| RSSI | ToA | MTS | C/I | soft-bits (254..0) |
+------+-----+-----+-----+--------------------+
- MTS (1 octet) - Modulation and Training Sequence info, and
- C/I (2 octets) - Carrier-to-Interference ratio (big endian).
== Coding of MTS: Modulation and Training Sequence info
3GPP TS 45.002 version 15.1.0 defines several modulation types,
and a few sets of training sequences for each type. The most
common are GMSK and 8-PSK (which is used in EDGE).
+-----------------+---------------------------------------+
| 7 6 5 4 3 2 1 0 | bit numbers (value range) |
+-----------------+---------------------------------------+
| . . . . . X X X | Training Sequence Code (0..7) |
+-----------------+---------------------------------------+
| . X X X X . . . | Modulation, TS set number (see below) |
+-----------------+---------------------------------------+
| X . . . . . . . | IDLE / nope frame indication (0 or 1) |
+-----------------+---------------------------------------+
The bit number 7 (MSB) is set to high when either nothing has been
detected, or during IDLE frames, so we can deliver noise levels,
and avoid clock gaps on the L1 side. Other bits are ignored,
and should be set to low (0) in this case.
== Coding of modulation and TS set number
GMSK has 4 sets of training sequences (see tables 5.2.3a-d),
while 8-PSK (see tables 5.2.3f-g) and the others have 2 sets.
Access and Synchronization bursts also have several synch.
sequences.
+-----------------+---------------------------------------+
| 7 6 5 4 3 2 1 0 | bit numbers (value range) |
+-----------------+---------------------------------------+
| . 0 0 X X . . . | GMSK, 4 TS sets (0..3) |
+-----------------+---------------------------------------+
| . 0 1 0 X . . . | 8-PSK, 2 TS sets (0..1) |
+-----------------+---------------------------------------+
| . 0 1 1 X . . . | AQPSK, 2 TS sets (0..1) |
+-----------------+---------------------------------------+
| . 1 0 0 X . . . | 16QAM, 2 TS sets (0..1) |
+-----------------+---------------------------------------+
| . 1 0 1 X . . . | 32QAM, 2 TS sets (0..1) |
+-----------------+---------------------------------------+
| . 1 1 1 X . . . | RESERVED (0) |
+-----------------+---------------------------------------+
== C/I: Carrier-to-Interference ratio
The C/I value is computed from the training sequence of each burst,
where we can compare the "ideal" training sequence with the actual
training sequence, and then express that difference in centiBels.
== Limitations
- The only supported modulation types are GMSK and 8-PSK.
Messages with other modulation types will be rejected.
- IDLE / NOPE indications are not (yet) handled.
- The logical channel handlers do not (yet) handle optional
fields, such as TSC and C/I. This will be implemented
in the follow-up changes.

It may be necessary to extend the message specific header with
more information. Since this is not a TLV-based protocol, we
need to include the header format version.
+-----------------+---------------------------+
| 7 6 5 4 3 2 1 0 | bit numbers (value range) |
+-----------------+---------------------------+
| X X X X . . . . | header version (0..15) |
+-----------------+---------------------------+
| . . . . . X X X | TDMA TN (0..7) |
+-----------------+---------------------------+
| . . . . X . . . | RESERVED (0) |
+-----------------+---------------------------+
Instead of prepending an additional byte, it was decided to use
4 MSB bits of the first octet, which used to be zero-initialized
due to the value range of TDMA TN (0..7). Therefore the current
header format has implicit version 0.
Otherwise Wireshark (or trx_sniff.py) would have to guess the
header version, or alternatively follow the control channel
looking for the version setting command.
This change introduces a new structure 'trx_ul_burst_ind', which
represents an Uplink burst and the corresponding meta info. The
purpose of this structure is to avoid overloading the existing
functions, such as trx_sched_ul_burst(), with more and more
arguments every time we bump the version.
On receipt of a TRXD message, trx_data_read_cb() now parses
the header version, and calls the corresponding dissector
functions, e.g. trx_data_handle_(hdr|burst)_v0().

Let's avoid fancy alignment in the description of logical channels
for the benefits of having better readability, the ability to add
more comments and fields without making it look ugly.
Get rid of value-string array 'trx_chan_type_names', since each
logical channel has its name defined in 'trx_chan_desc'.
Get rid of field 'chan' of 'trx_lchan_desc' structure since it's
not used anywhere, and not actually needed because the position
of each lchan description is defined by its TRXC_* type.
Replace both 'pdch' and 'auto_active' fields with more generic
bitmask field called 'flags', and define the following flags:
- TRX_CHAN_FLAG_AUTO_ACTIVE,
- TRX_CHAN_FLAG_PDCH.
Use RSL channel mode #defines from libosmogsm instead of having
hard-coded numbers. This increases readability.
As a bonus, let's add a human readable description to each lchan
definition, so it can be printed in the VTY some day.

This way we unify format. We take the chance to add related information
to some log messages which were not printing that information (and was
confusing when using more than one phy instance).

osmo-bts cannot provide GPRS service while osmo-pcu is not connected.
The BSC has no knowledge of the PCU connection state. Prevent MSs
from trying to register for GPRS while the PCU is disconnected by
erasing the GPRS Indicator in SI3.

Example: The fact that the PCU has connected with a given version is not
a *failure* in the first place, particularly not a MAJOR one. Let's
allow callers of oml_tx_failure_event_rep() specify the serverity of the
event that they're reporting to the BSC.

This adds the final missing part to full CBCH support:
* keep a tab on the current queue length for basic + extended CBCH
* keep rate counters about the number of sent / transmitted SMSCB
* send CBCH LOAD information via RSL to the BSC

This avoids having to iterate the list to count the number of elements.

The logic for Extended CBCH are the same as for the Basic CBCH, we just
need to
* duplicate our related state
* parse the optional RSL_IE_SMSCB_CHAN_INDICATOR IE
* start to send data on the Extended CBCH (TB=4..7)

The BSC can not only send us each to-be-sent message separately, but
it can also configure a DEFAULT message, which is then to be sent
instead of the NULL message. Let's add support for this

As specified in 3GPP TS 03.60 Section 16.2.1 and 44.018 Section 3.4.15,
a Class B MS is sending a "RR GPRS SUSPEND REQ" via a DCCH to the BTS if
it wants to suspend GPRS services. The BSS is now responsible to
somehow forward this to the SGSN. As the Gs interface between BSC and
SGSN is both optional and doesn't have any provision to forward this
message, we have to send it over to the PCU so it can use regular BSSGP
signaling to inform the SGSN of the SUSPEND REQUEST.
This patch requires libosmocore Change-Id
I90113044460a6c511ced14f588876c4280d1cac7 for the related definition of
struct gsm48_gprs_susp_req.

At some locations in the code a signal to SS_FAIL is dispatched in order
to trigger the sending of an OML failure event report in oml.c. This is
a bit overcomplicated for the task. Lets use oml_tx_failure_event_rep()
to send the failure event reports and lets remove the signal handler for
SS_FAIL.

The function oml_tx_failure_event_rep() replaces oml_fail_rep(), so lets
use only oml_tx_failure_event_rep() and remove oml_fail_rep()

The function gsmnet_from_vty() is used in oc2gbts_vty.c, but it is not
declared in vty.h. Lets add the declaration to vty.h, so that
gsmnet_from_vty() can be used properly by other modules.

It's only used inside of gsm_data_shared.c so let's mark it as such.
