7cf54b2541 Change binpac exceptions in AYIYA/GTP analyzers to do protocol_violation 
As opposed to creating weirds for e.g. "binpac::ExceptionOutOfBound".
The protocol_violation will also result in the disabling of the
analyzer by default.

9edbf3e53c Add GPRS Tunnelling Protocol (GTPv1) decapsulation. 
This currently supports automatic decapsulation of GTP-U packets on
UDP port 2152.

The GTPv1 headers for such tunnels can be inspected by handling the
"gtpv1_g_pdu_packet" event, which has a parameter of type "gtpv1_hdr".

Analyzer and test cases are derived from submissions by Carsten Langer.

Addresses #690.
