gsmtap: Add support for E1/T1 traces
GSMTAP has recently gained support for wrapping E1/T1 protocol traces.
This is very useful as contrary to pcap/wtap file based protocol traces,
GSMTAP can be streamed in real-time.
The GSMTAP pseudo-header encodes information such as
* the E1/T1 timeslot number
* the E1/T1 subeslot number (if I.460 is used)
* the E1/T1 line/span number (somewhat awkwardly as 'antenna number')
* the payload (LAPD, Frame Relay, TRAU, ...)
In this first implementation in wireshark, only FR and LAPD
sub-dissectors are added. The other payloads (TRAU) do not have any
wireshark dissectors so far.
