Earlier there was an incorrect encoding of PUAN when VQ is not equal
VR case for EGPRS UL RLC window. The PCU was encoding the same PUAN
message always irrespective of radio condition. This was a bottle neck
for performance testing. Which has been fixed in this patch.
Related: OS#1793
unit test assertion in the previous commit is fixed in this patch.

This patch adds a test case which expects a current bug with EGPRS PUAN
encoding when VQ != VR. The test's expectation is corrected along with
the bugfix in a subsequent commit
Adds test_tbf_puan_urbb_len to describe the following bug:
EGPRS PUAN encoding disregards the urbb_len, leading to identical PUAN
messages regardless of the urbb_len.

Modify the EGPRS DL TBF flow to support Split block during
Retx. This patch will also Upgrade the test suite with test cases
to validate the EGPRS Downlink SPB for Retransmission
Scenarios like MCS6->MCS3, MCS4->MCS1, MCS5->MCS2, MCS9->MCS3
MCS7->MCS2, MCS8->MCS3 have been simulated and Integration tested
in NuRAN 1.0 hardware thoroughly.

Modify the header files with necessary data structure to handle
Split block for EGPRS DL TBF.
The EGPRS resegmentation feature allows PCU to retransmit
RLC blocks of HeaderType1, HeaderType2 by segmenting
them to 2 HeaderType3 blocks(Example MCS5 will be
retransmitted as 2 MCS2 blocks). Table 10.4.8b.2 of 44.060
explains the possible values of SPB in HeadrType3 for DL
direction. The PCU decides to retransmit the
blocks by resegmenting it based on Table 8.1.1.1 of 44.060.
The retransmission MCS is calculated based on current MCS of
the Block and demanded MCS by PCU. Section 10.3a.3.3 of 44.060
shows the HeadrType3 with SPB field present in it

The new $with_dsp matrix parameter is defined as "sysmo" or empty/"none". The
lc15 DSP might be added in the future.
Fetch the sysmo layer 1 API only if with_dsp==sysmo.
The new $with_vty parameter is independent of $with_dsp, it is now up to
jenkins to define a matrix filter.
For compat, until jenkins is reconfigured with the new matrix parameters, use
$sysmodsp to init the new parameters to reflect previous behavior. The
$sysmobts matrix parameter made no sense, drop it.

This patch will modify the EGPRS UL TBF flow to support Split block

in NuRAN 1.0 hardware thoroughly. The scope of Unit testing is limited.

Modify header files with data structures required
to support split blocks for EGPRS UL TBF
This feature provides provision for MS to retransmit
RLC blocks of HeaderType1, HeaderType2 by segmenting
them to 2 HeaderType3 blocks(Example MCS5 will be
retransmitted as 2 MCS2 blocks). Table 10.4.8b.1 of 44.060
explains the possible values of SPB in HeadrType3 for UL
direction. When the MCS is changed at the PCU, PCU directs the
changed MCS to MS by PUAN or UPLINK ASSIGNMENT message along
with RESEGMENT flag, Then MS may decide to retransmit the
blocks by resegmenting it based on Table 8.1.1.1 of 44.060.
The retransmission MCS is calculated based on current MCS of
the Block and demanded MCS by PCU. Section 10.3a.4.3 of 44.060
shows the HeadrType3 with SPB field present in it.

Check Timing Advance validity and set corresponding bit for Immediate
Assignment message. Previously !polling was errorneously used (polling
bit has nothing to do with TA validity according to 3GPP TS 44.018 Table
10.5.2.16.1) which lead to TA being always valid as polling is always 0
in other parts of the code.

Remove note on PCCCH/PBCCH support because according to 3GPP TS 44.060
version 12.5.0 Release 12 § 1.6 "The network shall never enable PBCCH
and PCCCH".
The rationale behind this from GP-091955:
"Due to that P-channels are not deployed by any operator and are not
expected ever to be, it has decided to remove the requirement on
mandatory support of P-channels for the mobile stations in A/Gb mode."

Those structs are not used anywhere (which was the case in the commit
which introduced them as well) but give false-positives while grepping

EGPRS Type 1, 2, and 3 headers are used by OsmoPCU and OsmoBTS.
Move the header definitions to libosmocore to be shared by both
packages.
Modify the struct variable naming to use *_hi/*_lo instead of
*_a/*_b in order to be consistent with existing naming used in
libosmocore.

This routine has been moved from from here to libosmocore and as
part of the C++ -> C the reference got converted to a pointer. We
have a lot of code that calls the method with the reference and
instead of updating the callers, create a short inline wrapper to
call the C routine.

During MCS upgradation such as MCS6->MCS9, 2 blocks which
were sent separately as MCS6, will be clubbed into one MCS9
block during retransmission. Same holds good for
MCS5->MCS7 transistion. During MCS reduction such as
MCS9->MCS6,2 blocks which were sent together will be
sent separately during the retransmission case.
Same is verified through the generated log file. Currently
MCS8->MCS6 transition is not supported. The retransmission
MCS is being calculated from Table 8.1.1.2 of TS 44.060.
The same test cases are also integration tested on Nuran
1.0 platform.
