GMPLS update - 40: adding in-segment activation handler

Added #in-segment #activation #handler in GMPLS module. On activating the in-segment it #enables the #LSP #segment operations on it. i.e. It #starts #receiving the #LSP #labelled #data on the interface. When cross-connect is also activated the received data will switched to the respective out-segments - with the respective out-going labels. And further passed to the out-going interfaces, thus completing the #label-switched #data-path.

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.
