flags.
	(fhandler_base::open): Ditto.
	* fhandler_floppy.cc (fhandler_dev_floppy::open): Don't allocate devbuf
	in O_DIRECT case.
	* fhandler_raw.cc (fhandler_dev_raw::ioctl): Don't allow buffer
	changes in O_DIRECT case.  Allow returning a buffer size 0, which
	indicates O_DIRECT.
	* fhandler_tape.cc (fhandler_dev_tape::open): Use O_SYNC flag to
	hand down the !buffer_writes case.  Don't allocate devbuf in O_DIRECT
	case.
	(fhandler_dev_tape::raw_read): Don't mess with devbuf if it's NULL.
	* include/fcntl.h: Define _FDIRECT, O_DIRECT, O_DSYNC and O_RSYNC.
	* include/cygwin/version.h: Bump API minor version.
