Since there can be multiple PDCH channels configured on different
timeslots, different TRXes, and BTSes, the PTCCH/U handling code
in OsmoPCU needs to know the exact origin of a given RACH.ind.
Otherwise, it is not known which subscriber originated a given
PTCCH/U indication, and hence it is impossible to send PTCCH/D
Timing Advance notification properly.
Fortunately, we can extend the RACH.ind message without even
bumping the protocol version, because every single PDU has a
fixed size defined by the largest message - INFO.ind. In case
if the actual message payload is smaller, the rest is filled
with a constant padding byte (0x00).
Older versions of OsmoPCU will consider the new fields as padding,
while the messages from older OsmoBTS versions will always have
both fields set to 0x00. Since C0/TS0 cannot be configured to
PDCH, this can be easily detected on the other end.

Some of our files didn't have a copyright notice at all, let's add
it. Also, update the notices in other files and ensure a SPDX
identifier is present in all but the most trivial files.

Prior to this patch, the test accepted anything as list of IPv4
endpoints in the PCU-originated SNS-CONFIG PDU. Using this patch,
the corect IPv4 address and UDP port number is verified.

As per section 6.2.1 of 3GPP TS 48.016, the initial IP/port where the
SNS SIZE/CONFIG procedures are being performed is not automatically part
of the later NS-VCs. This means we shall not perform the NS-ALIVE
procedure or any other procedure beyond SNS with that specific endpoint.
This adds a new TC_sns_1c1u_separate() to test for this behavior.

If there's only one IP/PORT/NSVC, we cannot expect something happening
on another NSVC. In this test case, only index 0 / NSVC0 is used.

Let's split the PCUIF-side component from the NS-side component
and create a new RAW_Test_CT which derives from both.

The SNS-enabled Gb interface has no RESET/BLOCK/UNBLOCK procedures,
but introduces a bunch of new SNS procedures. Most importantly the
SNS-SIZE and SNS-CONFIG procedures.
