[c-nsp] reset peering session after withdrawing a more specific route

[Jeff Chan]

We are growing a /20 to a /19 and I'm wondering if we can simply
start announcing the new route and stop announcing the old route
without resetting our peering sessions.  Would the internal/external
route maps be happy with this or is a reset necessary?  (We have
updated our outbound prefix filters appropriately and so have our
peers.)  Would the old route get appropriately dropped externally
this way?

Probably this is a newbie question for folks who do this all the
time, but we do it pretty infrequently.
