Log message:
Prevent recursions by not deleting entries inside rtable_walk(9).
rtable_walk(9) now passes a routing entry back to the caller when
a non zero value is returned and if it asked for it.
This allows us to call rtdeletemsg()/rtrequest_delete() from the
caller without creating a recursion because of rtflushclone().
Multicast code hasn't been adapted and is still possibly creating
recursions. However multicast route entries aren't cloned so if
a recursion exists it isn't because of rtflushclone().
Fix stack exhaustion triggered by the use of "-msave-args".
Issue reported by D??niel L??vai on bugs@ confirmed by and ok bluhm@.
