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).
Let's fix this by using proper mcs_chan_code() function which returns
Channel Coding Command for MCS without the need to further correct it
and adjust expected tests output accordingly.

Add function to encode MCS value as proper EDGE or GPRS Channel Coding
value according to 3GPP TS 44.060 and corresponding helpers.
Use it for everything except IA Rest Octet encoding which is done in a
follow-up patches to make sure that we distinguish between
encoding-related changes to test output and unrelated changes.

This is a much safe way, it allows for modifications of the debug
subsystem enum member values without breakage. Also, the syntax
introduced here is what we do in all other Osmocom CNI projects.

As specified in 3GPP TS 03.60 Section 16.2.1 and 44.018 Section 3.4.15,
a Class B MS is sending a "RR GPRS SUSPEND REQ" via a DCCH to the BTS if
it wants to suspend GPRS services. As of
Change-Id I3c1af662c8f0d3d22da200638480f6ef05c3ed1f, OsmoBTS forwards
this via the PCU socket, so we need to pick it up and send it via BSSGP
to the SGSN.

In Change-Id I787fed84a7b613158a5618dd5cffafe4e4927234 in February 2018
we accidentially introduced a change that would erroneously swap
the endianness of the CellID on the way between PCUIF socket and
BSGSP. This meant that all OsmoPCU based BTSs would report the
wrong CellId to the SGSN.

In preparation for Channel Coding Command encoder in follow-up patches

helpers from GprsCodingScheme class but without CamelCase and with less
typo chances between Gprs and Egprs cases.

Move Mode (EDGE/GPRS) definition and related functions outside of
GprsCodingScheme class. This allows us to use standard libosmocore
value_string functions.

The TAI is described as { 0 | 1 < TIMING_ADVANCE_INDEX : bit (4) > } in
3GPP TS 44.018 §10.5.2.16.1 so it should be encoded with if-else.

Move functions which compute number of blocks or bits depending on
header type and corresponding enum outside of GprsCodingScheme
class. This will allows us to use standard libosmocore value_sting
functions in upcoming patches for IA Rest Octet encoding/decoding.

Add method to explicitly cleanup BTS singleton similar to GprsMsStorage
class and use it from main(). The destructor becomes trivial wrapper
around cleanup() method.
This prevents annoying SIGABRT on exit of OsmoPCU caused by
rate_ctr_group_free() being called after talloc_free() which removes the
context in which counter group is allocated.
Change-Id: I796d56a7de3f3a1f9d59708995c8e3e9b05a2747
It's confusing to have test-specific helper with the same name as tested
function directly inside the GprsMsStorage class. Let's convert it into
static function and move to the unit test.

This ensures that the rpath of the generated binaries is set to use only

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.
Change-Id: I3ae1ee64ec8e80247b8fe669cc79505b4dadf58f
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.

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.

Add new environment variables WITH_MANUALS and PUBLISH to control if
the manuals should be built and uploaded. Describe all environment vars
on top of the file.
When WITH_MANUALS is set, install osmo-gsm-manuals like any other

and "make distcheck"). Add the bin subdir of the installed files to
PATH, so osmo-gsm-manuals-check-depends can be used by ./configure.
