 Handle all router-control messages. These  are messages destined for the
AMIRTR program itself.
 
Packet type/Sub-type combos recognized here:
 
PK_DEBUG
    PS_START 	- enable debug with level given
    PS_RESUME	- close, open new version of all debug files
    PS_STOP	- stop debugging
 
PK_MONITOR
    PS_START	- start/restart monitor on given/saved file
    PS_RESUME	- close, open new version of monitor (log) file(s)
    PS_STOP	- stop (all) logging
 
PK_ORDERLY_ABORT - set Exit_Request
    ***NOTE*** - this will take the router to a quiscient state, but may
    		not actually cause it to exit. The router will attempt
    		to shut down all active links, but may hang (waiting for
    		one or more links to drop) due to lack of cooperation at
    		the other end. The guarantee is, however, that it will
    		be OK to abort after this (and a few seconds).
 
PK_IDENTIFY	- return a friendly message
