Two new dissectors have been added for the BSSAP component on the Lb (MSC-SMLC)
interface:

packet-lb_bssmap_le.c: Defines the BSSMAP LE dissector for the Lb interface as
per 3GPP TS 49.031

packet-lb_bsslap.c: Is the BSSLAP dissector for the Lb interface as defined in
3GPP TS 48.071 techincal specification

Changes to the existing packet-bssap.c were required so that Wireshark can be
configured (via preferences) to differentiate between the GSM-A interface and
the Lb interface.

Changes to the existing packet-bsslap.c file made to differentiate between the
gsm_bsslap and lb_bsslap protocols.

Testing was performed with custom built test harness and live traffic trace
files.
