	* daemon/display.c, daemon/gdm.c: the waitpid function doesn't work
	  as I expected with respect to signals so emulate it with either
	  sleep or pause and then a WNOHANG waitpid.  Also kill the
	  XKeepsCrashing thing if we get a SIGTERM, SIGINT or SIGHUP,
	  just like with the slaves.  The slaves are now killed at least
	  once in 10 seconds in case they are hanging somewhere.

	* daemon/gdm.c: set up a TERM/INT handler for the first few moments,
	  which will kill the extra process if any in addition to exiting.

	* daemon/misc.c: fix the gdm_signal_default to use SIG_DFL and
	  not SIG_IGN, doh! and fix extra_process check a little

	* daemon/server.c, daemon/slave.c: fix server start race that
	  could result in the USR1 to not set SERVER_RUNNING, and fix
	  slave not to try to open the display again if the server
	  is gone.
