I noticed that TC_egprs_pkt_chan_req_reject_exhaustion has started
to fail since the refactoring change [1]. As it turned out, this
test case does not init a GprsMs instance, which is needed by a
function it depends on - f_TC_egprs_pkt_chan_req().
I don't really see the point of using the GprsMs abstraction for
such small test cases sending just a few messages, which do not
require us to keep any state. Let's just revert those changes,
and keep using the low level API.

- Get rid of f_L1CTL_DM_EST_REQ, it's not really needed.
- Derive ts_L1CTL_DM_EST_REQ_H0 from ts_L1CTL_DM_EST_REQ.
- Turn all its params into (value) templates.
- Turn it into a (value) template itself.
- Pass GsmArfcn directly to ts_L1CTL_DM_EST_REQ_H0.

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.

Both f_ms_rx_imm_ass_ccch() and f_ms_establish_ul_tbf() functions
are actually twin brothers of good old f_pcuif_rx_imm_ass() and
f_establish_tbf() with some minor changes.
The former accepts a GprsMS parameter, that is never used. The
latter simply calls f_ultbf_new_from_rr_imm_ass() in the end.
Let's avoid code duplication:
- call f_establish_tbf() from f_ms_establish_ul_tbf(),
- remove f_ms_rx_imm_ass_ccch(), use f_pcuif_rx_imm_ass().
After the removal of f_ms_rx_imm_ass_ccch(), the implementation
of TC_ta_idle_dl_tbf_ass() does not need the GprsMS state, so
let's make it look like it was before.

Before this patch, each test had to somehow keep state for all the
transactions needed. Now, most of the state is moved to generic GprsMS,
UlTbf and DlTbf structures, and APIs to maintain its state, as well as
function helpers to submit or receive messages from it. For now
specially the Tx side was improved, some of the Rx parts are left for
later and are still using the old APIs.
This will allow for more complex scenarios and more complex tests
running several MS.
All the tests were updated to use the new APIs, reworked when needed and
even totally rewritten in some cases since they were doing
inconsistent/wrong stuff from the point of view of what the scenarios
or code paths they were expected to test. There's no test regressions.

We don't (yet) support multi-BTS test cases anyway. Ideally, each
virtual BTS would be a separate component with an individual port.

Since change [1], the IPA emulation component allows us to handle
multiple IPA connections, thus multiple RSL connections. The idea
is to attach a TCP/IP connection identifier to each message.
On top of that, this change implements mapping between TCP/IP
connection identifiers and RSL stream identifiers, so we can
finally talk to any of connected transceivers (up to 4 for now),
not only the last connected one (as it was before). The actual
mapping is done during the IPA identification procedure.
Instead of forwarding ASP_IPA_EVENT_UP to a test case, the RSL
emulation component now sends a new event - RSLEM_EV_TRX_UP,
with transceiver number (actually, IPA stream-id) attached.

This would allow the RSL Emulation component to maintain several
transceiver connections in server mode. In order to send an RSL
message to a specific transceiver, its TCP/IP connection ID needs
to be included in the ASP_RSL_Unitdata message.

This change basically does two simple things:
a) adds TCP connection identifier to ASP_IPA_Event,
b) splits g_ipa_conn_id into g_self_conn_id and g_last_conn_id.
Change a) would let the upper layers of code (based on the IPA
emulation component) know which TCP/IP connection a given event
belongs/relates to.
Change b) solves the problem, happening in server mode when a new
client connects, and TCP/IP connection identifier of another
previously connected client gets overwritten.
With this change applied, g_self_conn_id holds TCP/IP connection
identifier of the client or server itself (depending on g_mode),
while g_last_conn_id is only used in server mode and holds
connection identifier of the last connected client.

As a side effect of change [1], the RSL emulation component has
stopped to handle RSL messages from transceivers other than
TRX#0. Let's fix this by using template '?' for stream ID.

Send 7 RACH indications to the IUT with EGPRS Packet Channel Request.
Since we have only one timeslot (and USF value '111'B is reserved),
the 8-th indication should be properly rejected by the IUT.

At the moment, the IUT does not support any emergency services.
Make sure that EGPRS Packet Channel Request for an emergency call
is properly rejected (RR Immediate Assignment Reject).
Note that at the time of writing this test, the IUT does not
handle EGPRS Packet Channel Request properly, so it fails.

The purpose of this test case is to verify the contents of RR
Immediate Assignment Reject message (and its IAR Rest Octets)
sent in response to EGPRS Packet Channel Request (11 bit RA).
To provoke the reject message, test case crafts an incorrect
EGPRS Packet Channel Request message ('111111xxxxx'B).
Note that at the time of writing this test, the IUT does not
handle EGPRS Packet Channel Request properly, so it fails.
