Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
...
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

Change the kernel mmap interface so that the offset to map is an
...
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

Changed grf mmap that it is closer to XFree. VGA memory on et4000/et6000
...
is now at offset 0xa0000.

- Provide the reasonable size that can/may be mmap-ed. This might differ
...
from the current frame buffer size.
- The et-driver now allows for a 16Kb io-region (was 8Kb) that can be
mapped. The XFree server uses this.

Checkpointing my et4000 work. Note that the et-console will not be

functional until the minimal pci-support is checked in.

Remove the pointer to view_t from the grf-structure, use viewview(dev)
...
to obtain the pointer instead. This removes a kernel-crash that happened
when something was written to the console while the console was being
resized.

ite_newsize(): Do not reallocate a display when the actual display mode

bitmap.
