* 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

* Move way too verbose command description to the manuals.
* None of these commands apply immediately, correct the attributes.
** Remove meaningless call to l1if_provision_transceiver_trx().
* Make 'maxdlynb' hidden, so it only appears in the expert mode.
* One GMSK symbol actually corresponds to 550m.

This step is required while turning off the BTS without killing the
process. Right now only osmo-bts-trx supports this feature, so this
function is only available and used by osmo-bts-trx.
Later on, when the feature is support more generally, we can move call
to this function to common place like bts_shutdown_fsm or alike.

The BCCH carrier (sometimes called C0) of a BTS shall maintain
discontinuous Downlink transmission at full power in order to
stay 'visible' to the mobile stations. Because of that, early
versions of 3GPP TS 45.008 prohibited BS power reduction on C0.
However, in the recent 3GPP TS 45.008 there is a feature called
'BCCH carrier power reduction operation'. This is a special
mode of operation, where the variation of RF level for some
timeslots is relaxed for the purpose of energy saving.
In BCCH carrier power reduction operation, for timeslots on the
C0 carrier, except timeslots carrying BCCH/CCCH, the output power
may be lower than the output power used for timeslots carrying
BCCH/CCCH. In this case the maximum allowed difference in output
power actually transmitted by the BTS is 6 dB.
The power reduction operation can be controlled by the BSC by
sending BS POWER CONTROL on the A-bis/RSL with the Channel Number
IE set to 0x80 (RSL_CHAN_BCCH). This makes osmo-bts reduce the
transmission power on inactive timeslots of the BCCH carrier.
This is a non-standard, Osmocom specific extension, so indicate
support of this feature to the BSC in the feature vector. Also
add a VTY command to allow enabling/disabling the power reduction
locally. Add some signalling notes to the A-bis/RSL manual.
For more details, see 3GPP TS 45.008, section 7.1.

This change implements general interference averaging logic for
the higher layers. In l1sap_info_time_ind(), where we receive
TDMA time updates from BTS model, call rsl_tx_rf_res() for each
transceiver according to the interval defined by the Intave
parameter received from the BSC. In rsl_tx_rf_res() perform
the actual averaging for each inactive logical channel, and
then send everything to the BSC over the A-bis/RSL.
The BTS model specific code needs to report the measurements
for each logical channel every 104 TDMA frames (SACCH period)
by calling gsm_lchan_interf_meas_push().

Unfortunately, we cannot re-use the existing Makefile rules from:
$(OSMO_GSM_MANUALS_DIR)/build/Makefile.vty-reference.inc
because they do not allow to generate the list of $(DOCBOOKS) from
a template, and require the project to store everything in separate
folders with specific names. Also, those rules expect that the
target PDFs contain only a single word in their names (for example,
'osmoapp-vty-reference', not 'osmo-app-vty-reference'), while in a
project with multiple similarly named targets this would reduce
readability (imagine 'osmotrxuhd-vty-reference').

osmotrx fn-advance (which is the clock_advance variable here) and
osmotrx rts-advance together make up the minimum delay the BTS can react
to a channel request, etc.
The default of 20 are around 92ms which is clearly too much. With
modern hardware and using SCHED_RR a lower value should not be an issue.
See OS#4487 for some related measurements on more CPU-limited devices like a
LimeNet-micro3.

The sample configs supplied within the doc/trx directory set the
rx-gain parameter to 1. A low value like this may cause a noticeable
degration of rx performance (For an USRP B200 an rx-gain of 38dbm is
recommended). Lets remove this seting from the sample configuration to
allow the default settings in osmo-trx to be applied.

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.
