rlcmac: add dissection of 2G->3G/4G PS handover

Port from wireshark.git 428ee66ae1c524b49f9043729b1f1e9b4f52f409, from
Pascal Quantin.

The original commit is also changing the RRC_Container field to
M_CALLBACK, but we leave them as M_VAR_ARRAY since the callback is
basically used to add more dissection information in wireshark.
