Move generic MCS enum to C header file to simplify further modifications
to GprsCodingScheme class in follow-up patches. This also allows us
to use standard libosmocore value_sting functions in upcoming patches
for IA Rest Octet encoding/decoding.

Previously some of the errors in update_cs_ul() call were silently
ignored. Let's log all those as errors with appropriate message.
Note: test output needs updating because we do not (yet) set proper meas
struct in TBF tests. That's likely wrong but it's better to update tests
in a separate commit.

Previously MAX_GPRS_CS was used for both EDGE and GPRS which means that
we waste extra memory in GPRS case. It also leads to misleading
name. Let's fix this by introducing separate definitions for GPRS and
EDGE cases and use them as appropriate in limit checks.

The headerTypeControl() function always return constant and is only used
inside OSMO_ASSERT() which compares it to the very same constant which
makes it no-op. Let's remove this clutter.

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.
That's partially based on reverted commit 529ce885450946d85d1920fb3d1a994c3efe5849.

In preparation for upcoming patches with 11 bit RACH and TA support,
let's restructure existing encoders to simplify further modifications:
* move consistency checks to top-level Imm. Ass. encoder
* use consistent formatting
* constify pointers where appropriate
* split SBA and MBA encoders into separate functions
Those changes also make it obvious which parameters are necessary for
Rest Octets in each specific case (DL, UL-SBA, UL-MBA, UL-SBA-EGPRS,
UL-MBA-EGPRS).
There're no functional code changes so there's no need to adjust tests.

introduced the use of timespecsub(). Unfortuantely, we also
accidentially removed the call to osmo_clock_gettime() along
with it, leaving now_tv completely uninitialized.

The return code from bssgp_tlv_parse() was not checked for a parsing
error. In case of a parsing error the stored return code could have
been overwritten later in this function.
Explicitly check for a parsing error, log corresponding packets,
and return an "invalid mandatory information" error status to
the sender. To avoid loops, do not respond with an error status
to STATUS PDUs.

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.

The previous implementation unconditionally subtracted nanosecond
values from different time measurements, causing overflow if the
current measurement was taken in less of a fraction of a second
than the past measurement. Use timespecsub() instead, which
accounts for nanoseconds correctly.
Also, fix calculations of KBit/s throughtput. It was not being
calculated correctly, since it was actually accounting for one
KB per 128th-part-of-a-second.

There have been test failures on the osmo-pcu Jenkins builders due

to clock_gettime() with CLOCK_MONOTONIC to prevent time from going
backwards and causing negative time deltas in calculations.

In libosmocore, we normally register a SIGHUP handler for log file
rotation.
However, the osmo-pcu code so far installed its own signal handler,
which did exactly nothing in the SIGHUP case.
Let's fix this by removing SIGHUP handling here, letting libosmocore
take care about this.

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.
