gsmtap: Add defintions for GSMTAP based remote logging
Often it is useful to have log statements from the osmocom programs synchronized with protocol traces. So rather than having to open the pcap file with GSMTAP or other protocol data side-by-side with the textual log of one or more network elements, we simply pass the log lines around as GSMTAP messages, which can then be displayed in-order and interspersed with the protocol messages inside wireshark.
