From Florent.Drouin@alcatel.fr
Add the same workaround used in packet-ftam.c for the bad handling of the asn "IMPLICIT SEQUENCE", in the packet-gsm_map-template.c. This patch concerns Map V3 messages, not correctly decoded with the previous workaround "offset=offset+2".
Change a parameter for Provide Roaming Number decoding.
Add a decoding fonction for "Channel needed" parameter to avoid a decoding error for Paging messages
with a change to actually dissct channel needed.
