* fhandler.h (enum query_state): Drop redundant query_stat_control.

Browse Source 
* fhandler.cc (fhandler_base::open): Ditto.  Add READ_CONTROL to
	access and FILE_OPEN_FOR_BACKUP_INTENT to create_options when opening
	for writing.  Always set security attributes to avoid calling
	has_acls.
	* fhandler_disk_file.cc (fhandler_base::fstat_fs): Don't try to
	open file twice.
