	Merge from setuid-branch.  Changes also by Martin Hunt
	<hunt@redhat.com>.
	
	* control.c (_stp_ctl_write): Make sure we don't overflow.
	(_stp_ctl_open_cmd): Do not allow multiple opens of the control
	file.
	(_stp_ctl_write_cmd): Once STP_START is received, ignore
	everything except STP_EXIT.  Create another state variable
	"initialized". Don't respond to STP_SYMBOLS or STP_MODULES unless
	initialized is 0. Also check that current pid is the same as the
	pid that did insmod.
	(_stp_register_ctl_channel): Bug fix - sets owner/group after
	checking for NULL.
	
	* procfs.c (_stp_ctl_write): Make sure we don't overflow.
	(_stp_ctl_open_cmd): Do not allow multiple opens of the control
	file.
	(_stp_ctl_write_cmd): Once STP_START is received, ignore
	everything except STP_EXIT.  Create another state variable
	"initialized". Don't respond to STP_SYMBOLS or STP_MODULES unless
	initialized is 0. Also check that current pid is the same as the
	pid that did insmod.
	(_stp_register_ctl_channel): Set ownership of cmd file and percpu
	files for bulkmode.
	
	* relayfs.c (utt_trace_setup): Set ownership of percpu files.
	Improved error handling.
	(utt_trace_remove): Improved error checking.
	
	* utt.c (utt_remove_tree): Improved error checking.
	(utt_trace_cleanup): Ditto.
	(utt_create_buf_file_callback): Set file ownership.
