Add FP over UDP dissection via heuristic

Build Information:
wireshark 1.3.2 (SVN Rev 30873 from /trunk)

Copyright 1998-2009 Gerald Combs <gerald@xxxxxxxxxxxxx> and contributors.
This is free software; see the source for copying conditions. There is NO

Compiled with GTK+ 2.14.4, with GLib 2.18.2, with libpcap 0.9.8, with libz
1.2.3.3, without POSIX capabilities, without libpcre, without SMI, without
c-ares, without ADNS, without Lua, without Python, without GnuTLS, without
Gcrypt, without Kerberos, without GeoIP, without PortAudio, without AirPcap,
with new_packet_list.
NOTE: this build doesn't support the "matches" operator for Wireshark filter
syntax.

Running on Linux 2.6.27-14-generic, with libpcap version 0.9.8.

Built using gcc 4.3.2.

Add a heuristic to the UMTS FP parser in order to handle FP traffic sent via
UDP. The mechanism relies on 3 facts:

* An fp_info struct must be attached to the packet
* The link_type field of the fp_info struct must indicate that the packet was
transmitted via Ethernet
* UDP source and destination ports are used to distinguish between the 'lower
layer' transport UDP and the 'upper layer' user data (which can also be UDP)
