[PATCH] openbsc[master]: rtp_proxy.c: Ensure msgb_alloc is large enough for largest A...

Review at https://gerrit.osmocom.org/91 rtp_proxy.c: Ensure msgb_alloc is large enough for largest AMR frame In AMR 12.2 (mode 7), the actual RTP payload is 33 bytes. Howeerver, as we store the length of the (dynamically-sized) AMR payload in the first byte, our buffer needs at least 33+1 byte in size.
