	* config/Xsession.in: eek, it's /dev/null, not dev/null

	* daemon/misc.[ch], daemon/gdm.c, daemon/slave.c:
	  Fix #117527, get the root user name from the passwd info
	  rather then assuming it's "root".

	* configure.in: fix #117895, when --with-xinerama=no, don't
	  do the xinerama checks and just don't use xinerama

	* daemon/slave.c:  Fix counting bugs in gdm_in_signal to
	  fix hangs

	* daemon/slave.c: Fix the waiting for notify when
	  inside the usr2 signal handler.

	* daemon/gdm.c, daemon/slave.c: Redo the waitpid mess and
	  just use a pipe and select kind of stuff.  Also remove
	  the greeter restarts from within signal handlers as we
	  can just do it now by popping out of the select and doing
	  it there.  This fixes a bunch of races and hangs related
	  to doing too many things from signal handlers.  Also
	  don't do waitpid from the main daemon for slaves children
	  as it won't work anyway and kill ...
