agch: Merge IMM.ASS.REJ if possible when enqueueingzecke/jerlbeck/agch-queue

This patch implements merging of IMMEDIATE ASSIGN REJECT messages as
sugegsted in GSM 08.58, 5.7. When a new IMM.ASS.REJ is to be appended
to the AGCH queue and the last message in that queue is of the same
type, the individual entries (up to 4 per message) of both messages
are extracted, combined and stored back. If there are less than 5
entries all entries fit into the old message and the new one is
discarded. Otherwise, the old message will contain 4 entries and the
remaining ones are stored into the new one which is then appended to
the queue.
