[j-nsp] RSVP to LDP migration

[Phil Bedard]

It's fairly simple.  Just turn up LDP everywhere, make sure the LDP paths
exist in inet.3 and then turn off RSVP or set the preference on RSVP
higher.   You can tunnel LDP over RSVP so if you are just adding gear to
the edge of the existing network it may be easier to turn on LDPoRSVP and
just run LDP on interfaces at the edge.
