The TBF tests are failing on some machines due to unexpected
log output: "DL packet loss of IMSI= / TLLI=0xffeeddcc: 0%"
These messages are printed if >= 1 second has passed between
loss reports. This timing is machine-dependent so the test
is unstable as a result. Only print these messages at log
level debug to (hopefully) make TBF tests pass consistently.
Update expected test output accordingly.

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.

Move computation of RX mask into separate function and document it. This
allows to significantly shrink find_multi_slot() function and overall
improve code readability.
Since the test output requires cosmetic adjustment anyway due to change

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

The table B.1 is copy-pasted from 3GPP TS 45.002 and reformatted via
Emacs macros into C struct to avoid typos. The test output expanded

So far the allocation was only tested up to hardcoded MS class 29. Drop
that assumption and test for all supported MS classes. Adjust expected
test output as necessary.
Note: using mslot_class_max() forces allocation for MS classes 30 and 31
for which no actual data is available (will be added in follow-up
patches) which current implementation treats differently depending on
TX/RX direction - see gprs_alloc_max_dl_slots_per_ms(). Because of that
we have to adjust the expected number of allocations in
test_successive_allocation() as well.

This function contains 3 independent test cases. Let's split them into
separate functions to simplify further modifications:
* split test cases into separate functions
* use them for mass test as well
* change function names to avoid confusion
* make individual test cases return error instead of failing via assert
on allocation failure
The top-level test_alloc_b() is used as part of exhaustion tests in
test_all_alloc_b() for example, so it's expected that allocation might
fail (due to TFI or USF exhaustion for example) eventually. In this case
it's better to indicate it to caller instead of failing entire program.
The test output does not require any adjustements because we do not
exhaust to the point of allocation failure yet.

Previously TBF got single timer so the pending timer was automatically
cancelled when new one was scheduled. Let's make it more robust by
implementing independent T31 xx timers from 3GPP TS 44.060 §13.2 with
corresponding start/stop functions and counters.
The semantics of the timers is preserved as before: pending timers are
restarted unconditionally. It might be neecessary to change this later on
after spec review.
N. B. T0: used for assign/reject timeouts, have to be properly
attributed and documented first.
