In recent osmo-pcu commits, initial fn was changed to invalid value -1,
in order to be able to detect FN jumps. previously, the initial value
was set randomly to 0, which was wrong anyway because first FN received
from the BTS could be any other FN counted by the BTS at that time.
This makes some tests fail because they send RACH.ind + RTS.ind to
receive the Imm Assignment, and the Request reference in the Imm Assign
was calculated on the invalid unset FN "-1", hence it won't match test
expectancies.
In order to fix it, simply make sure the TDMA clock is initiated by
sending a DATA.ind to the PCU before tests start doing stuff
(f_init_raw() is blocked waiting for BTS_EV_SI13_NEGO).

PCUIF will be updated to always send DATA.ind for each expected block FN
on any activated PDCH slot, irrespective of whether valid data was
received or not, similarly to what's done already for TRXDv1 NOPE.ind in
TRXD and TCH channels in OsmoBTS. The aim at this change is to be able to
track TDMA clock in an accurate way without hops, and hence be able to
detect on time whether expected UL blocks (SF, RRBP poll) didn't arrive.
Older osmo-pcu versions can cope well with this change, they will simply
print an error upon ach data_len=0 messages received and submit a GSMTAP
block, then discard it, so tests still pass.
Nevertheless, a new module parameter is added to disable this new
behavior in order to avoid logs and pcap files ending up clogged with
uneeded information until a new osmo-pcu release appears.

We initialize those verbose structures over and over in different tests,
and we usually don't care about detials, only whether they enable EGPRS
or not.
So let's define them once and reuse them in tests whenever possible.
Some tests requiring specific values (eg to test allocation of 8 PDCH on
a single TBF) are left intact.

Allow ignoring for received dumy packets while waiting for a Pkt Ass on
PACCH. This fixes some tests failing sometimes due to race condition
where rlcmac packet is requested too quicky, after the PCU has received

The function is splitted into an internal altestep + a wrap function
which is compatible with tests already using it.

Since sending with the network-requested UL CS/MCS was implemented, CS-2
is being used in the test (since it's requested by the network during UL
Imm Ass). We used to send UL blocks with CS-1 prior to that, which means
we are sending a different amount of data, and hence the test
expectancies need to be updated.

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.

Once GPRS/EGPRS multiplexed support is ready, it will be controlled
through pcu info_ind.flags by enabling
MCS or not; the "egprs only" VTY comamnd will be dropped.
The usual setup would be to support both GPRS+EGPRS, so make that the default.
Most tests require to be passed the _noMCS variant to work in older
versions of PCU, since those versions use the "egprs only" concept which
will reject egprs_ms_class=0. Same tests enabling MCS in newer osmo-pcu
shouldn't be a problem.

older versions of osmo-pcu were broken and were only allocating TBFs in

better to allocate TBFs across different TRX. That's why the test needs
to be fixed to set up only 1 TRX in order to run into the same scenario.
