Share a single instance of 'pcu_l1_meas' between all unit tests,
set initial measurement values in main(). This way we can get

Do not use C++11 extended initializers to prevent the following error.
AppInfoTest.cpp:109:54: error: extended initializer lists only available with -std=c++11 or -std=gnu++11
pcu_prim.u.app_info_req = {0, 15, {0xff, 0x00, 0xff}};
I ran into this when modifying the gerrit build verification job to
build with docker (which still uses GCC-4.9).

This commit would also remove the option from config_write_pcu() since
it's automatically filled in by osmo_tdef, but there was actually a bug
because that param was never printed when saving the config...

osmo-pcu code is really verbose, and since log lines printing start and
end of tests are sent to a different file, it's really difficult to
understand which test outputs what.

Receive an Application Information Request from the BTS via PCU

This will allow for configuration of some of the timers by the user,
and allow him to inspect current values being used.
It will be also useful for TTCN3 tests which may want to test some of
the timers without having to wait for lots of time.
Timers are splitted into 2 groups: BTS controlled ones and PCU controlled
ones. The BTS controlled ones are read-only by the user (hence no
"timer" VTY command is provided to change them).
TbfTest.err output changes due to timers being set up correctly as a
consequence of changes. Other application such as pcu_emu.cpp and
pcu_main.cpp had to previosuly set the initial values by hand (and did
so), but apparently TbfTest.c was missing that part, which is now fixed
for free.

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.

The instance bssgp_nsi is a global instance to be used by all
NS related functions. Previous the PCU allocated and initialized
the bssgp_nsi instance when (re-)connecting and freeing on disconnect.
The problem of the implicit initialisation is gprs_ns_vty_init(bssgp_nsi).
All vty init functions must be called before the configuration is read,
otherwise a previous vty written configuration is invalid.
Furthermore the vty modifications to the `ns` object were lost when the PCU has to
reconnect to the SGSN.

Right now set_mode() on GprsMs behaves in pretty counter-intuitive way:
* it's possible to set current DL MCS higher than max value
* EGPRS and EGPRS_GMSK have the same max DL MCS
* setting EGPRS* mode drops current/max MCS values to unknown
Let's capture this in a unit-test before attempting any further
modifications.

Write TAI (if available) when generating Rest Octets for UL
Assignment. This should not affect actual PCU behavior because TAI is
not yet supported by upper layers but we have to adjust corresponding
tests anyway.

Use bitvec_set_*() directly without external write pointer tracking to
simplify the code. This is part of IA Rest Octets (3GPP TS 44.018
§10.5.2.16) which is the last part of the message so it should not
interfere with the rest of encoding functions.
The difference in the expected test output is due to proper handling of
TAI which should not be transmitted for SBA according to the Note in
Table 10.5.2.16.1 in 3GPP TS 44.018.
The change was manually tested against real mobile phone using options
'gprs mode gprs' in osmo-bsc.cfg and 'two-phase-access' in osmo-pcu.cfg
to make sure appropriate code path is actually triggered.
That's partially based on reverted commit 93d947f5e8.

Previously result of ".to_num() - 1" was used without any checks which
means that in case of to_num() returning zero we would effectively try
to encode (uint8_t)(-1).

Channel Coding Command for MCS without the need to further correct it
and adjust expected tests output accordingly.

The TBF tests are failing on some machines due to unexpected

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.
