X reinit code trapped

[Aivils S. <ai...@un...>]

Hi, All!

	All nvidia cards sometimes cannot be initialzed
if multiple servers runs simultaneous. I create patch,
which disable SIGHUP disaster. Of course this patch is
not very _unix_ compatible. By defautl X server on
SIGHUP must do all duties, be we don't like some duties.
	After patch applying X on SIGHUP clean up client connections.
only. X authentification reset himself, because reread
actual user authentification file on each client connection.
Now X leave alone videocard on user logoff.
Paranoidal sysops must not use this patch.

Patch attached
