Add an osmo-bts meta-package that depends on the subpackages
osmo-bts-trx and osmo-bts-virtual. This is important, because the
downstream packaging of debian does not split osmo-bts in subpackages,
it has only one osmo-bts package. So without this, when installing
"osmo-bts" in debian while having the Osmocom binary package repository
installed and expecting to get the newer version, the user will actually
get the older version from debian.

The order of interference level boundaries is not clearly defined by
3GPP, so we should support both ascending and descending variants.

It may happen after the A-bis connection recovery that the RF RESource
INDication message gets sent too early, while some timeslots are not
yet configured. This confuses the BSC and provokes error messages.

Let's make sure all ts->pchan* related data is reset when we release the
TS. This is important for pchan_is, since in bts-trx upon shutdown
finish the PDCH lchan of a osmo dyn TS is set to
lchan->state=LCHAN_S_NONE, and as a result when the PCU tries to release
it by means of PCUIF act_req later, it may be ignored since the lchan is
already in erased state.

As a side effect, we have to sacrifice a unit test (TC_inval_dummy)
because it becomes impossible to pass a dummy or invalid SACCH block
to lchan_bs_pwr_ctrl().

Currently an Uplink SACCH block is being passed to LAPDm first, and
then gets forwareded to the BSC in handle_ms_meas_report(), together
with the Uplink measurements collected so far.
This approach has a serious flaw: handle_ms_meas_report() won't be
called if an Uplink block contains SAPI=3 data (SMS) or was not
decoded at all (len=0) fow whatever reason. Therefore, no RSL
MEASurement RESult message will be sent to the BSC.
Rename handle_ms_meas_report() to lchan_meas_handle_sacch(), and call
it from l1sap_ph_data_ind(). This way perioduc RSL MEASurement RESult
messages will be sent regardless of what happens on Uplink SACCH.

about missing dl prim
This scenario is actually expected when the call is being set up or torn
down, since we may not be receiving RTP from the MGW to send to the MS.
Hence, let's lower the log level to DEBUG to avoid having log clogged
for each call start/stop if INFO is used.

Recent commit (see below) changed a check to avoid weird results for msg
which had l2h=NULL, since l2len would return unexpected results there.
However, some code branches like FACCH or TCH seem to be always setting
l2h even if len=0. Hence, we must test either of the 2 scenarios (null
pointer and l2len()).
This commit fixes the following message appearing all the time during
calls:
"""
TCH/F: Prim has odd len=0 != 23
"""

It cannot happen that msg1 is NULL and msg2 is not null, since they are
deuqueed from same place. Only possible combinations are:
msg1!=NULL && msg2!=NULL
msg1!=NULL && msg2==NULL

* Remove deprecated configuration options:
'osmotrx timing-advance-loop' is deprecated, Timing Advance loop is now active by default
'osmotrx ms-power-loop <-127-127>' is deprecated, MS Power Control is now managed by BSC
* Adjust 'ipa unit-id' (1801 -> 6969) to match the one from the example osmo-bsc.cfg
* Set clock advance values to known working values:
+ 'osmotrx fn-advance' -> 20
+ 'osmotrx rts-advance' -> 5
* Set 'nominal-tx-power' since the calypso-bts tranceiver does not support NOMTXPOWER

In 2/3 cases when calling process_l1sap_meas_data() we already have
a pointer to the logical channel, so let's pass it as the first
argument instead of a pointer to the transceiver. This way we
avoid calling get_active_lchan_by_chan_nr() two times.
In l1sap_ph_data_ind(), call process_l1sap_meas_data() below the
conditional branch handling PDCH, so it won't be called for
GSM_LCHAN_PDTCH anymore. GPRS specific measurements are handled
by the PCU and not of interest for the BSC.

After merging the patch [1] fixing handling of the RLL RELease

The problem is actually *not* in patch [1], but in the older one
[2] which we attempted to fix. While a logical channel is in
signalling mode, the lower layers do not produce PRIM_TCH_RTS,
and thus the l1sap_tch_rts_ind() is not being called.
Unlike l1sap_tch_rts_ind(), the l1sap_ph_rts_ind() is being called
regardless of the channel mode (signalling vs speech), so let's
move handling of lchan->pending_rel_ind_msg there.

It could happen if for instance l1 code called trx_sched_clean() when
closing the phy, and after that some code called (erroneously)
trx_sched_set_lchan(). Let's make sure we don't allow other modules to
crash the process when using this function.

This avoids triggering all sorts of unexpected paths where one tries to
release an already released lchan, etc.
This can happen for instance if BTS shuts down due to BSC link going
down, and hence resets all lchans, announcing it to the PCU. Then the
PCU may try to deactivate the channel sending act_req (disable), but the
BTS already unilaterally dropped the channels.
That code path seems to trigger some crash, probably because something
in lchan has been freed.

This reverts commit 8a85b71167c4580ddf9e6c59ea602475fd462b3a.
This is actually the wrong fix. Proper fix comes as a follow-up patch,
since the root cause happens earlier in upper layers. No msg with
l2h=NULL should reach this point of code ever.

PCU idle blocks are identified by being 0 length, and hence msg->l2h
being null. Don't try to encode those, but simply discard them silently.
In case there's a missing block in C0, we want to log the event since
the BTS is expected to send something on C0.

With this change the error case is moved at the end of the function,
which is more usual. At the same time, one goto tag can be removed,
simplifying the function.

This adds a --enable-systemtap configure option, which will then
add static tracepoints to the generated osmo-bts-* binary.
At this point, only two sets of tracepoints are supported, and
only in osmo-bts-trx: ul_data_{start,done} and dl_rts_{start,done}.
The probes are intended to be used for analyzing the amount of time
needed for processing of uplink bursts / generation of downlink bursts.
