* mach/Machrules: Use -include for $(*.ir).
* hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS): Mask off type bits in
request values.
* sysdeps/mach/hurd/ioctls.h (_IOC_NOTYPE): New macro.
(_IOT_COUNT2): Field is 3 bits, not 2.
* sysdeps/mach/hurd/ioctl.c: Ignore handler if it fails with ENOTTY.
* hurd/hurdioctl.c (_hurd_lookup_ioctl_handler): Mask off type
bits before looking up handler.
(fioctl): Use __hurd_dfail.
(fioctl, fioclex): Use ENOTTY for bogus request instead of EGRATUITOUS.

* sysdeps/alpha/memchr.c (memchr): loop searching for matching
character bailed out one too early; changed constant 6 to
7 to fix this.
