Introduce CRC and FSM for IuUP (user plane) as used in 3G RTP data
Only support for SMpSDU mode is introduced in this commit. Not supported explicit list: - Transparent mode - ATM/AAL2 based Transport layer - GTP-U based Transport Layer - Iu Rate Control procedure - Time Alignment procedure APIs are provided to allocate the primitives properly inside the related msgb. This way primitives can be placed in the headroom, leaving the data part of the msgb for the IuUP payload, hence allowing re-use of the msgb and 0 copy of IuUP payload when forwarding data over RNL<->TNL. Since RNL and TNL primitives relu struct osmo_prim_header, which is not packed, they cannot be set to packed, and hence proper memory alignment in the msgb must be done to avoid misaligned accesses (Asan errors about it otherwise). Related: SYS#5516 Change-Id: Ibe356fa7b1abaca0091e368db8478e79c09c6cb0
