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. See also the fix of expected test data in patch

There is an extra zero octet at the end of the test data, which does not
get encoded back. The test currently does not detect this, but will in
upcoming patch I85e715326e1d8f4f301f82f78da109f1a7a92f30.

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.

A RANAP RAB-AssignmentRelease may contain a ReleaseList. In order to
detect that a RAB is about to be released we need to be able to check if
the RAB we are dealing with is contained in such a ReleaseList.

A RANAP RAB-AssignmentResponse may contain a FailedList. In order to
detect that a RAB Assignment failed at the HNB we need to be able to
check if the RAB we are dealing with is contained an such a FailedList.

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.

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.
