Subject: 	* fhandler_disk_file.cc (fhandler_base::open_fs): Change 
 set_file_attribute call to indicate that NT security isn't used. 
 (fhandler_disk_file::fchmod): Rearrange to isolate 9x related 	statements. 
 Do not set FILE_ATTRIBUTE_SYSTEM. 	(fhandler_disk_file::fchown): Check
 noop case first. 	* fhandler.cc (fhandler_base::open9x): Remove ntsec
 related statements. 	(fhandler_base::set_name): Do not set namehash. 
 * fhandler.h (fhandler_base::get_namehash): Compute and set namehash if 
 needed. 	* syscalls.cc (access): Verify that fh is not NULL. Do not set
 PC_FULL. 	(chmod): Ditto. 	(chown_worker): Ditto. 	(stat_worker):
 Ditto. Verify if the path exists.
