This patch adds the handling of Spare Extension bytes
to UMTS Frame Protocol. It also handles the case when
the presence of CRC in dedicated channels is not known
(i.e. when FP from a K12/K15 log is dissected).
The new functionality is placed in the new function
"dissect_spare_extension_and_crc". The "dch_crc_present"
field inside "struct fp_info" (file packet-umts_fp.h)
is also extended to handle the case of unknown CRC presence.
Much of other changes is to update "offset" variable and
return it so that the location of Spare Extension and CRC
is available.
The patch also include a small tweak to handle Frame
Protocol information saved from K15. Some fields appear
8 bytes later compared to K12. The changes are in the file
packet-k12.c.

Also:
- Fix a division-by-zero error in FP dissector
- Correct the way DCT2000 IPPrim addresses and ports are dissected and displayed

In the attached patch, the K12 wiretap now saves the content of record
after captured packet data. The K12 dissector then could extract them and provide
useful information to properly dissect FP frames (user plane of UTRAN Iub
interface).
