lib: Fix race condition in shutdown of routemap

When shutting down a daemon that uses an update
timer to handle route map processing, there
exists a race condition where if you change
a route map and then immediately shutdown
quagga before the update timer for the routemap
runs, you will be placed in a infinite loop.

This condition happens because this commit introduces
route map memory free'ing but never tests to see
if the to_be_processed flag has happened or not

    bgpd, lib: memory cleanups for valgrind, plus debug changes

Modify route_map_finish to explicitly turn off the to_be_processed
field.  As that we know we are going away if route_map_finish is
called.
