* autoload.cc (NtCreateFile): Add.

Browse Source 
* dir.cc (mkdir): Change set_file_attribute call to indicate that
	NT security isn't used.
	* fhandler.cc (fhandler_base::open_9x): New method, created from
	fhandler_base::open.
	(fhandler_base::open): Rearrange to use NtCreateFile instead of
	CreateFile.
	* fhandler.h (enum query_state): Redefine query_null_access to
	query_stat_control.  query_null_access isn't allowed in NtCreateFile.
	(fhandler_base::open_9x): Declare.
	* fhandler_disk_file.cc (fhandler_base::fstat_fs): Use
	query_stat_control first, query_read_control if that fails.
	(fhandler_disk_file::fchmod): Call enable_restore_privilege before
	trying to open for query_write_control.  Don't fall back to
	opening for query_read_control.
	(fhandler_disk_file::fchown): Ditto.
	(fhandler_disk_file::facl):  Only request restore privilege and query
	access necessary for given cmd.
	* fhandler_raw.cc (fhandler_dev_raw::open): Call fhandler_base::open
	instead of opening device here.
	* ntdll.h (NtCreateFile): Declare.
	* path.cc (symlink_worker): Change set_file_attribute call to indicate
	that NT security isn't used.
	* sec_acl.cc (getacl): Fix bracketing.
	* sec_helper.cc (enable_restore_privilege): New function.
	* security.cc (str2buf2uni_cat): New function.
	(write_sd): Don't request restore permission here.
	* security.h (set_process_privileges): Drop stale declaration.
	(str2buf2uni): Declare.
	(str2buf2uni_cat): Declare.
	(enable_restore_privilege): Declare.
	* syscalls.cc (fchown32): Return immediate success on 9x.
