* fhandler.cc (fhandler_base::open_9x): Handle O_SYNC and O_DIRECT
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.
