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. svn path=/trunk/; revision=21726
