Pau Espin 4fbeefd8cf pcu: Relax some CS/MCS expectancy checks
Previous commit implemented the CS/MCS verification, and hence now some
tests fail because they had too restrictive checks.

In theory the verifications could be done so restrictive by configuring
the PCU accordingly at the start of the test, but we are not
really interested in checking the exact CS/MCS in these tests, only
checking if GPRS/EGPRS is being used.

Pau Espin 5abfded61e RLCMAC_EncDec: Provide decoded (m)cs in (E)GPRS data blocks
Let's provide this information to higher layer since CS is mostly
discovered by original bitstring size which is available during
decoding.

Call the size2mcs converter in each function to avoid having to pass it
as a parameter and have it selfcontained, meaning one can simply call
decode(bitstring) from TTCN3 code and be done with it.

Pau Espin 6791eb6b93 pcu: TC_mt_ping_pong: Request UL TBF on last DL ACK
Let's test the code path where UL TBF is requested through DL ACK/NACK
here, since we already test the usual UL TBF through CCCH approach in
most tests.

rlc_mode is changed to ACKED since that's the mode we are using so far
in tests.

Pau Espin 02c972d8aa pcu: use correct RA type to properly test 2phase access
Old code was not setting Single Block Packet Access type, and 2phase
access was not properly triggered.

Once it's triggered, message flow changes quite a lot from the 1phase
access, specially because the 2nd Ul Assignment arrives through PDCH
instead of CCCH, which means a different record is received and hence
code for 1phase cannot be easily re-used.

For similar reasons, f_tx_rlcmac_ul_n_blocks() is modified to receive
the only required tfi param instead of a full dl_block.

Some functions are also extended to support SingleBlock Allocation
instead of usual DynamicAllocation.

Vadim Yanitskiy b6733a67ec PCU: refactor and simplify f_rx_rlcmac_dl_block_exp_data()
This function was written in a way that it tries to do as
many different (but related) things as possible:

  a) send an RTS.req to the IUT, expect a DATA.ind in return,
  b) decode RLC/MAC message contained in the received DATA.ind,
  c) make sure that it's either GPRS or EGPRS data block,
  d) calculate the last TDMA frame number of RRBP using
     f_rrbp_ack_fn() regardless of its validity,
  e) make sure that the block contains a given LLC payload.

Everything is ok except point d). The problem is that this is
only the case for the first block of RRBP, and not applicable
to the rest having 'rrbp_valid' flag unset. Furthermore, this
function did not match GPRS DL blocks with 'rrbp_valid' flag
unset, for some odd reason.

Let's move RRBP calculation into a separate function called
f_dl_block_ack_fn() and return TDMA frame number of the
received DATA.ind message instead.

Among with that, there are more little changes:

  - simplify matching of (E)GPRS DL data blocks,
  - use 'in' qualifier in parameter list where possible,
  - turn parameter 'data' into a template (present).

Vadim Yanitskiy d4f22aaf31 library: enrich tr_RLCMAC_DATA_RRBP, rename to tr_RLCMAC_DATA_GPRS
Let's make this template more flexible, so it can be used to match
any GPRS DL data blocks, not only those with rrbp_valid == true.

Note that behavior of f_rx_rlcmac_dl_block_exp_data() is
intentionally left unchanged, and will be fixed later.
