GMPLS update - 64: hard-linking standard GMPLS out-segment entries

Hard-linked standard #GMPLS #out-segment entries with #standard #out-segment #entries in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #out-segment entry based #indexing. This will access the out-segment entries by using the #native #indexing. This removes references to the GMPLS out-segment indexing used earlier. This will reduce the memory requirement associated with the GMPLS out-segment entries. The GMPLS out-segment #entries add support for #attributes like #segment-direction, #ttl-decrement, #pointer to external parameters, etc ...
