[c-nsp] Graceful way to terminate BGP Session

[Jason Lixfeld]

Hi Scott,

If I may ask:  What problem are you actually trying to solve?  I  
can't see how the idea below saves you anything from just shutting  
down the session.  You still incur a CPU hit when you withdraw all  
your routes by no longer receiving them from the upstream, and the  
internet still recalculates if you change the local preference.
