GMPLS update - 25: adding standard extended LSR parameters

#Added #standard #extended #MPLS #LSR #parameters in the GMPLS module. This include the #extended #cross-connect #parameters as well. The extended cross-connect parameters add support for the bi-directional tunnel LSPs. The respective tunnel is referenced through the #tunnel #pointer and the cross-connect for the opposite direction is referenced through the #opposite-cross-connect #pointer. The cross-connect pointer is used for the #co-routed #bi-directional #tunnels and #associated #bi-directional #tunnels.
