Vadim Yanitskiy 36558d9526 library/PCUIF_Types.ttcn: extend RACH.ind with TRX / TS number fields 
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.
