GMPLS update - 46: optimizing standard extended GMPLS tunnel actual-path entries

Hard-linked #standard #extended GMPLS #tunnel #actual-path through #standard MPLS #tunnel actual-path #entries in GMPLS module. This will indicate the #extended #path-hop #attributes like flags indicating whether #hop-forward-label and #hop-reverse-label are present or not, pointers to these respective labels and #hop-protection status as in whether #local-protection is available in the hop and whether they are using it or not. This will reduce the memory requirement associated with the GMPLS actual-path entries. The hard-linked GMPLS actual-path entries enables accessing them directly from the standard MPLS actual-path entries.
