Sam Leffler ad67584665 Fix locking of the ip forwarding cache. We were holding a reference 
to a routing table entry w/o bumping the reference count or locking
against the entry being free'd.  This caused major havoc (for some
reason it appeared most frequently for folks running natd).  Fix
is to bump the reference count whenever we copy the route cache
contents into a private copy so the entry cannot be reclaimed out
from under us.  This is a short term fix as the forthcoming routing
table changes will eliminate this cache entirely.
