	* daemon/auth.c, daemon/filecheck.[ch], daemon/gdm.[ch],
	  daemon/misc.c, daemon/slave.c:  Auditing the file handling
	  stuff, increase general paranoia and code anality about
	  these things plus check pretty much every return of the
	  sete[ug]id even though they are pretty much guaranteed
	  to exist.  Being paranoid here is good.  Allow the
	  authentication cookie be given in upper case hex for
	  the socket protocol.
