commit a41f2563d040d86954ccda7faa4a8ad7bdbcae88

    darwin-nat: avoid crash while debugging gdb.
    
    it is possible that gdb gets mach exceptions from an unknown inferior.  This
    happens when an inferior creates a child and that child gets a signal.
    
    So instead of reporting messages with unknown origins, simply reply to these
    notifications. The kernel will then post the unix signal.
    
    gdb/
    	* darwin-nat.c (darwin_encode_reply): Add prototype.
    	(darwin_decode_exception_message): Reply to unknown inferiors.
    	(darwin_decode_message): Handle message by id.  Ignore message
    	to unknown inferior.
    	(darwin_wait): Discard unknown messages, add debug trace.
