ranap_rab_ass: add decoder and rewrite functions for RAB-AssignmentRequest/Response The RANAP RAB AssignmentRequest and AssignmentResponse contains the IP-Address and the IP-Port for the RTP voice stream. In the comming MGCP implementation we will have to extract and replace this information. Lets add functions that do that in a convinient way.

ranap_rab_ass_req_encode(): return msgb ranap_rab_ass_req_encode() forms a msgb, then copies the data to a buffer provided by the caller. Instead, just return the msgb. This removes one unnecessary memcpy() and simplifies some code. In ranap_rab_ass_test.c, actually ensure the correct size of the returned data.

ranap_rab_ass: ensure specific rab_id The parser functions currently ignore the rab_id. An exception is ranap_rab_ass_req_ies_extract_inet_addr, which extracts the rab_id of the first RAB. To make the handling of the RAB assignment parsing more robust lets add a rab_id parameter to the other functions. This parameter can then be used to ensure thet the correct RAB is handled.

ranap_rab_ass: check for more than one RAB assignment req The spec permits RAB AssignmentRequests with multiple RABs at a time. Even though one voice call is assigned only one RAB in practice. Since the current FSM implementation only supports a 1:1 scenario, lets check if the MSC really assigns only one RAB and block RAB Assignments that do not fit in this scheme.
