Unnumbered Interface Support in LDP

This feature allows LDP to establish Hello adjacency and to resolve unicast and multicast FECs
over unnumbered LDP interfaces.
This feature also extends the support of lsp-ping, p2mp-lsp-ping, and ldp-treetrace to test an LDP
unicast or multicast FEC which is resolved over an unnumbered LDP interface.

Feature Configuration

This feature does not introduce a new CLI command for adding an unnumbered interface into
LDP.
Note however that the fec-originate command has been extended to specify the interface name
since an unnumbered interface will not have an IP address of its own. The user can however
specify the interface name for numbered interfaces too.
See the CLI section for the changes to the fec-originate command.
