No need to pass -t num_trx anymore to specify number of TRX to use. It
is calculated based on dynamic allocation from VTY config.
Using parameter -t is flagged as deprecated and is transformed into a
NOOP por backward compatibility.
As a result, TRX now are allocated after the BTS is allocated and
initial config (pre-VTY) is applied.
A new function bts_trx_init() is added, to set default config on each
TRX during allocation and before setting VTY config on it.
A new per BTS model function bts_model_trx_init() is added, to allow
per model specific default configuration of each TRX.

All code in osmo-bts goes through APIs in libosmotrau (osmo_ortp.h),
hence direct dependency is not needed. Fixes OBS warnings:
dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/osmo-bts-trx/usr/bin/osmo-bts-trx was not linked against libortp.so.9 (it uses none of the library's symbols)
dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/osmo-bts-virtual/usr/bin/osmo-bts-omldummy debian/osmo-bts-virtual/usr/bin/osmo-bts-virtual were not linked against libortp.so.9 (they use none of the library's symbols)

gsm_bts_role_bts was introduced at a time when we still shared
gsm_data_shared.[ch] between BSC and BTS, and where we then subsequently
needed a BTS-private structure. Since that sharing was abandoned quite
some time ago, we can merge gsm_bts_role_bts into gsm_bts and do away
with the bts/btsb dualism in a lot of the code.

Previouslywe could end-up passing empty '-I' to compilerif corresponding
_INCDIR variable was not defined during the ./configure step. This is
apparently tolerated by gcc but still seems like a wrong thingto
do. Let's fix this by moving -I inside of *_INCDIR.

There's nothing sysmobts specific in this test so let's move it into
separate directory and run unconditionally. The test itself is unaltered
except for intro text.

* copy-paste gsm_data_shared.* from OpenBSC master
* remove corresponding configure check and option
* remove .deb dependency
Actual refactoring with removal of unnecessary structures/parts, moving
common OpenBSC/OsmoBSC parts into libraries etc. are left for further
patches.
Current patch will make coexistence with *BSC easier and will simplify
our build infrastructure.

Use libosmocodec function to parse RTP with AMR payload in sysmoBTS and
LC15. This replaces "manual" parsing of AMR frame with function covered
by test suite and makes adding DTXd support easier.

This removes a lot of copy+paste duplication between different BTS
models.
|
|
This also ensures that a missing ortp library dependency is discovered
at configure time already

sysmocom-bts model shuts down on link loss, but other models may not want
this, so shutdown is moved tor bts_model_abis_close of osmo-bts-sysmo.

MS uplink power control is required in pretty much any BTS, and we
cannot assume that they PHY / L1 will always take care of it by
itself. So the correspondign code is moved to common/power_control.c
and called from the generic part of L1SAP.
The corresponding VTY paramter has been moved from the sysmobts-specific
trx VTY node to the common BTS VTY node.

Currently the DSP is instructed to achieve a given uplink
power target but there are circumstances (e.g. EMV testing)
where we need more control over it. The "manual/software/osmo"
power control can only be implemented per TRX and not per
lchan. Add a very very basic control that checks the MS Power
used by the phone, the actual receive level and then adjust
the power.
The code doesn't take the history into account, if the phone
can not reach the requested power level the code will be stuck
(e.g. no timeout based on multiframes). It has a mode for a
fixed power control but no way to set it yet.
The change of the mode requires a restart of the software.

We need to build a lot more code to be able to test these two
new routines. I didn't want to move the code to a utils file
as the check is called from a hot path. Add accessors to the
inlined variant to be used by the unit test.
While writing the unit tests I noticed that a re-transmission
of the ciphering command would lead to an attempt to enable
ciphering again. I am not sure that this MphConfig is idempotent.

For systems with a bigger PA enabling the full output power at
once might draw more current than a power supply can provide. This
code will step up the output power in smaller steps to avoid this
situation.

During development one switches from GSM900 to GSM1800 and GSM850 to
GSM1900. This commit attempts to make this switch more easy.
GSM1800 and GSM1900 have overlapping ARFCNs. This means that the
mapping from bands to arfcn is not injective. Because of that I
removed the code to deduce the band from the ARFCN. This was done
in commit 8c3d807b3fc785ffb18aeb97355150c92221e8a0. The auto-band
option allows to move between GSM900/GSM1800 and GSM850/GSM1900.
Add a simple testcase with these auto-band configurations.
