There is a duality of initialization: early_init() in bts.cpp wants to init
logging even before static instances get initialized. Make sure that
tall_pcu_ctx is initialized during early_init() as well. There is a build
context that does not seem to include bts.cpp (osmo-pcu-remote), so to be sure,
init tall_pcu_ctx as NULL and both in early_init() as well as pcu_main.cpp,
init both tall_pcu_ctx and logging if it is still NULL.

Fix multiple problems around the sysmobts DSP access and headers:
- Use the proper variable name to detect the choice: $enable_sysmocom_bts was
not set anywhere and would actually be used from the current user env, if
present, instead of from configure args.
- Quote the $CPPFLAGS when assigning to oldCPPFLAGS and back.
- When checking SYSMOBTS_INCDIR, do not allow an empty "-I" without a dir.
- Ensure the --with-sysmobts path is used as an absolute path.
- Error out if --with-sysmobts is paired with --disable-sysmocom-dsp.
Also tweak reporting.
The resulting behavior now is:
./configure --disable-sysmocom-dsp

./configure --enable-sysmocom-dsp

Avoid runtime error seen on jenkins admin-deb9build slave, when building
osmo-pcu with_dsp=None,with_vty=False, during ts_alloc and tbf regression
tests:
+../../../src/mslot_class.c:271:36: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
+../../../src/mslot_class.c:272:22: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
This time it seems that these are all.
The master-osmo-pcu breaks on this since moving to a debian9 build slave.

Provide a sane means of adding the -Werror compiler flag.
Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"',
but that actually *overwrites* all the other CFLAGS we might want to have set.
Maintain these exceptions from -Werror:
a) deprecation (allow upstream to mark deprecation without breaking builds);
b) "#warning" pragmas (allow to remind ourselves of errors without breaking
builds)
As a last configure step before generating the output files, print the complete
CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

Receive the mnc_3_digits flag from the PCU interface.
Bump the PCU interface to 9.
This is one part of the three identical pcuif_proto.h patches:
- I49cd762c3c9d7ee6a82451bdf3ffa2a060767947 (osmo-bts)
- I787fed84a7b613158a5618dd5cffafe4e4927234 (osmo-pcu)
- I78f30aef7aa224b2e9db54c3a844d8f520b3aee0 (osmo-bsc)
Add 3-digit flags and use the new RAI and LAI API from libosmocore throughout
the code base to be able to handle an MNC < 100 that has three digits (leading
zeros).

The PDCH class and corresponding functions are rather self-contained and
independent from BTS implementation. Let's move them into separate file
to make bts.cpp more manageable. As additional benefit it allow us to
somewhat untangle all the different cross-dependent includes.

Move computation of RX mask into separate function and document it. This

Many files include unnecessary headers and don't include headers which
are actually used. Because of that combined with the fact that OsmoPCU
is a mixture of C and C++, it makes it hard to modularize code. Fix
this (using iwyu [1] tool):
* add missing headers
* remove unused headers

After the PCU socket becomes available, the BTS might send an
INFO_IND message with the 'ACTIVE' flag cleared. If this happens,
do not exit immediately, but keep retrying until an INFO_IND
message with the 'ACTIVE' flag arrives.
Note that this change only affects behaviour at process start-up time.
If the BTS switches from active to inactive state then osmo-pcu will
still exit. If this behaviour should be changed as well it could be
done in a follow-up patch.
Tested against osom-bsc + osmo-bts-virtual.
