mgcp/nat: Take payload type from SDP data
So far the payload type used in RTP streams has been taken from the
trunk configuration in NAT mode.
This patch changes the implementation to use the payload type
announced in the SDP part of MGCP messages and responses. SDP
descriptions more than one m=audio line are not yet supported
properly (always the last one is taken).
