CBSP (Cell Broadcast Service Protocol; 3GPP TS 48.049) support
This introduces definitions as well as a parser+encoder for the Cell Broadcast Service Protocol (CBSP) as specified in 3GPP TS 48.049. CBSP is used on the interface between CBC and BSC. Related: OS#3537 Change-Id: I5b7ae08f67e415967b60ac4b824db9e22ca00935
