In If1220852785853f8a5d8de183d5053ddd6ccb958 I introudced a config
file typo in the GBProxy_Tests.cfg. Let's fix that

The template restrictions are quite useful, becaue they give hints
to the TTCN-3 compiler, so it can spot more bugs. For example,
the lack of thereof would not prevent one from passing 'omit' to
a template, that assigns a value to a non-optional field, so that
might lead to a DTE at run-time in some cases.
Since adding 'template (restriction) ' to each template parameter
obviously makes templates look more cumbersome, let's move the
part with template name and arguments onto a separate line, just
like it's sometimes done for function definitions in C.

It will be easier to use this list / array in non-L1CTL specific
records and templates, e.g. in (RR) Immediate Assignment.

The new altstep reduces code duplication and simplifies access
to the L1 SACCH Header. It uses dec_SacchL1Header() to decode
the header, and would apply the received TA / MS Power level
values by default (see 'do_apply' parameter).

When doing load simulatin, the amount of console printing becomes a
serious throttle factor. We don't need to see the decode of every
message.

Those functions don't depend on any L3 specific data structurs, and
it is not a good idea to burden every user with having to impot all
of a 2G/3G Layer3 just to generate some hexstring identifiers.

We don't want the number of NSE and the number of BVC to be a
compile-time choice, but rather something dynamic at rutime. This
allows configuration files to define those details.

The Load Sharing Function distributes traffic among all unblocked NS-VC
within a NS-VCG. The sharing is done based on a LSP (Link Selector
Parameter) which is passed with the NS-UNITDATA.req primitive from BSSGP
to NS. Details are implementation specific, but NS must ensure that all
traffic of one LSP is always sent through the same NS-VC, as long as
that NS-VC is alive/unblocked.
We use the LSP as follows:
* Signaling BVC always only uses lsp 0
* PTP BVC messages unrelated to user straffic use a per-BVC static LSP,
which is the BVCI
* User traffic can set whatever LSP it wants
* NS keeps an array of NSVCs currently unblocked and uses the LSP modulo
the array size as an index into it

In case of a NS-VCG with multiple NS-VC, we must BVC-RESET only when the
first NS-VC becomes unblocked, i.e. as soon as we have any connection
to the peer at all. Whether we have further additional links doesn't
matter, at least not in the sense that all state should be reset.

This is something we need to simulate more complex scenarios,
particularly in the context of frame relay.

The test sets random bits for SI5 and expects to see those in dl SACCH. That
can only possibly work when that SI5 was actually sent to the BTS.

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.

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.

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.

Similar to the DL TBF counterpart from last commit, this time verifying
UL multislot TBF is allocated.

ARFCNs are allocated sequentially, so that conversion between
arfcn<->trx_nr is easily done.
Some helper functions are introduced to be able to submit and expect
messages on a given TRX+TS, which is required for setups with several
TRX and PDCH-enabled TS different than the default. These new APIs
will be used in PCU_Tests.ttcn in subsequent patches.

The change introduces three new test cases:
- TC_paging_cs_multi_ms_imsi,
- TC_paging_cs_multi_ms_tmsi,
- TC_paging_cs_multi_ms_imsi_tmsi.
Each of these establishes 56 Uplink TBFs, and then enqueues 56 CS
PAGING requests from the SGSN side. The main idea is to verify
encoding and compositing of the paging MIs in PACCH massages.
