Most of existing test cases are built on top of the PCU interface
abstraction components (see PCUIF_Components.ttcn). This means
that during the test case execution, additional components are
running in parallel, among with the MTC (Main Test Component).
When a test case terminates, either normally or due to an error,
it may happen that the virtual BTS component is stopped before
the associated TDMA clock generator. In this situation, sending
a clock indication towards the stopped BTS component would
lead to a dynamic test case error.
Let's take the process of tear down under control, and ensure that
the clock generator is stopped first. To achieve that, every test
case needs to call f_shutdown() in case of an error, as well as
in case of the normal termination.
Note we cannot use the existing f_shutdown() from Misc_Helpers,
because doing 'all component.stop' does not gurantee that the
clock generator is stopped first, and I experienced at least
one DTE while trying to integrate it.

In response to a CHANNEL REQUEST received on BCCH, the network
would never allocate a Downlink TBF, so we should always expect
an Uplink TBF assignment.

Back in September 2019, while writing the first lines of the new
test infrastructure for OsmoPCU, I picked a random value as the
default RA (CHANNEL REQUEST message) for Uplink TBF establishment.
It has been accepted by the IUT so far, and still works, but
according to 3GPP TS 44.018, table 9.1.8.1, value '3A'O has
nothing to do with GPRS - it actually means 'Answer to paging'.
The new value belongs to range '011110xx' - one phase packet
access with request for single timeslot uplink transmission.

So far we only checked presence of GPRS Indicator in the Rest
Octets of System Information Type 3, but this indicator is
also included in the Rest Octets of System Information Type 4.
Let's add additional test cases to check this indicator in the
Rest Octets of both message types. In order to achieve this:
a) refactor f_si3_has_gprs_indicator(), so it can handle
System Information Type 4 and its Rest Octets too;
b) separate common part from the existing test cases into
functions and (re)use them from the new ones;
c) in f_TC_pcu_socket_noconnect(), make sure to send
BCCH INFO with System Information Type 4.

We do have GPRS Indicator in SI3 Rest Octets, but for some reason
it was absent in SI4 Rest Octets. Let's finally enable it, so we

Finally, we can get rid of hard-coded octetstrings and control
every field of the Rest Octets we're sending to the IUT.
Note that template 'ts_SI4_default' did not contain any Rest
Octets at all, thus the GPRS indicator was (and still is)
absent. This will be fixed in a follow up change.

Due to a buggy nature of TITAN's padding attributes [1], we cannot
apply them to individual fields of the records that are embedded
into other structured types, like records and unions.
Ensure that encoded System Information messages are padded to
either 23 or 19 octets, depending on their type. In order to
achieve this, rename and wrap the external encoding function.

As it turned out, the length constraints introduced in [1] were
too strict. In particular, the use of FIELDLENGTH attribute made
it impossible to assign an octetstring of a smaller size and then
pad the remaining octets with '2B'O. TITAN would just use '00'O
instead, ignoring all my attempts to talk some sense into it.

Both are basically sub-types of GSM_RR_Types.RestOctets with length
constraints. We don't really need to have them as separate symbols,
especially since we have SI3RestOctets and SI4RestOctets now, so
let's apply these constraints within the corresponding records.

Commit [1] introduced multiple regressions, because it basically
changed the byte order in all fields of the whole module from
'first' (implicit default) to 'last'. This is not what we need.
Instead, let's apply BYTEORDER(last) to 5 bit 'ext_ra' fields
unless the bug [2] in TITAN's RAW codec is fixed.

Delete PCU_Tests.ttcn along with the configs, since they are broken and
we are only adding new tests to PCU_Tests_RAW.ttcn. They are broken
because it's not possible to run multiple tests after another.
Some components which used to be in PCU_Tests.ttcn and which were used
by other PCU_Tests*.ttcn files have been moved to SGSN_Components.ttcn
Selftests have been moved to PCU_selftest.ttcn.
Small placeholder for module PCU_Tests is left in PCU_Tests.ttcn to
still be able to compile the binary as "PCU_Tests" and avoid changing
that part of docker setup. We'll eventually rename RAW tests soon
anyway.

* RlcmacUlBlock and RlcmacDlBlock gain a new union field "egprs_data",
which is chosen when msg contains an egprs data block. Hence one can
use same structure for both gprs/egprs data and simply check
"ischosen(block.data_egprs)" to know whether it contains egprs or gprs
data block.
* C++ code in RLCMAC_EncDec.cc takes care of encoding and decoding of
each data header type and exposes a generic ttcn3 struct
"UlMacDataHeader" and "DlMacDataHeader". Decoded header type can be
found in mac_hdr.header_type. This can be used t5ogether with CPS to
get the MCS of the message received. Similarly, the encoder will use the
same field to know how to encode the ttcn3 structure.
* In RLCMAC_EncDec.cc order of functions has been ordered to split
between encoding and decoding, and inside these split between Ul and
Dl messages.
* Only encoding of UL HeaderType3 and decoding of Dl HeaderType3 is
implemented so far in RLCMAC_EncDec.cc. However, all code is already
arranged and functions prepared (with FIXME fprintf) to easily add the
missing header types once needed.
* Actually only the decoding of DL HeaderType3 has been tested to work so far.
Encoding may still be missing to octet-align the data block after the header.
All these wil lbe fixed once a test using them exists.

This change introduces three similar test cases:
- TC_egprs_pkt_chan_req_signalling,
- TC_egprs_pkt_chan_req_one_phase,
- TC_egprs_pkt_chan_req_two_phase,
which basically send several 11 bit RACH.ind messages to the IUT
containing different variations of EGPRS Packet Channel Request.
Depending on the establisment cause, for each RACH.ind we expect
to receive an Immediate Assignment containing an EGPRS Packet
Uplink Assignment in its Rest Octets.
All test cases make sure that Request Reference in the received
Immediate Assignment messages is set to 127 as required by 3GPP
TS 44.018 (see table 9.1.8.1, note 2b), and the Extended RA IE in
the Rest Octets matches 5 LSBs of the RA value that was sent.

By default, the BYTEORDER for BIT1..N sub-types is set to 'first'.
This may result in incorrect decoding of bit-fields located on the
boundary of two octets. For example:
IA Rest Octets
L... .... = First Discriminator Bit: Low
.H.. .... = Second Discriminator Bit: High
..0. .... = Discriminator bit: EGPRS Packet Uplink Assignment
...0 .... = Downlink/Uplink: EGPRS Packet Uplink Assignment
EGPRS Packet Uplink Assignment
.... 0001 1... .... = Extended_RA: 3 // <------------ (!)
.0.. .... = Access Technologies Request: Not Present
..1. .... = TFI/Multiblock: TFI Assignment Present
...0 0000 = TFI_Assignment: 0
As can be seen, the field 'Extended_RA' in this particular case
occupies 4 LSBs of the first octet and 1 MSB of the second. So
instead of '00011'B, TITAN's RAW codec decodes '10001'B.
