Add GPRS Tunnelling Protocol (GTPv1) decapsulation.

Browse source 
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.
