* fhandler.cc (fhandler_base::open): Set query access mode according

Browse Source 
to query_open setting.
	(fhandler_base::fhandler_base): Initialize query_open.
	* fhandler.h (FH_QUERYOPEN): Drop.
	(enum query_state): Add.
	(class fhandler_base): Add query_open member.
	(fhandler_base::get_query_open): Redefine to use query_open.
	(fhandler_base::set_query_open): Ditto.
	* fhandler_disk_file.cc (fhandler_base::fstat_fs): Remove O_DIROPEN
	from open_flags since it's added in open_fs anyway.  Remove
	query_open_already.  Use new query_open settings.  Rearrange slightly.
	(fhandler_base::fstat_helper): Add get_io_handle as parameter to
	get_file_attribute.
	* security.cc (get_nt_object_attribute): Make returning an int.
	Return -1 on error, 0 otherwise.
	(get_file_attribute): Take an object handle as argument. Move down
	to allow calling get_nt_object_attribute in case a non-NULL handle
	is given.
	* security.h (get_file_attribute): Add handle to argument list.
	* syscalls.cc (chown_worker): Accomodate new definition of
	get_file_attribute.
