	* sysdeps/unix/sysv/linux/sys/mtio.h: Moved to...
	* sysdeps/gnu/sys/mtio.h: ...here.
	(_IOT_mtop, _IOT_mtget, _IOT_mtpos, _IOT_mtconfiginfo): New macros.
	* sysdeps/gnu/Dist: Add sys/mtio.h.
	* sysdeps/unix/sysv/linux/Dist: Remove sys/mtio.h.
	* sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc]
	(sysdep_headers): Don't add sys/mtio.h here.
	* sysdeps/gnu/Makefile [$(subdir) = misc] (sysdep_headers): Add it
	here instead.

	Revamp Hurd ioctl typing magic to handle `struct' keyword in the
	ioctl command macros, so we can use Unix-compatible headers that
	make use of the _IO* macros.
	* sysdeps/mach/hurd/bits/ioctls.h (_IOC_ENCODE_TYPE,
	_IOC_ENCODE_TYPE_1, _IOC_ENCODE_TYPE_2, _IOTBASE_struct): New macros.
	(_IOR, _IOW, _IOWR): Use them _IOC_ENCODE_TYPE(t) instead of _IOT_##t.
	(_IOT_int, _IOT_char, _IOT_short): Renamed to _IOT__IOTBASE_*.
	(numerous ioctl command macros): Restore `struct' keyword.
