SNDCP: add SNDCP-XID encoder/decoder and unit test
The SNDCP-XID (or layer-3 xid) is used to exchange layer-3 parameters such as compression. The encoder encodes a bytestream that is then sent as regular XID field from LLC. We will need the SNDCP-XID to negotiate the parameters for our upcomming GPRS data and header compression features Change-Id: If2d63fe2550864cafef3156b1dc0629037c49c1e
