PBB customer backbone port update - 5

Updating customer backbone port ( #CBP ) service mapping routine in bridge module with #HAL calls. Corresponding to the #mapping of local service #I-SID s - from external port or the internal ILAN from I-Component - to the backbone I-SID, #B-VID & #DST-MAC pair the HAL operations are performed. This causes the real service mapping to be done in #data-path / #data-plane as well, making a forwarding path.
