mibstore.h and its miInitializeBackingStore() have been otherwise empty
since at least xorg-server 1.10. remove all reference to them as the
header is gone in xorg-server 1.18.

use WSDISPLAYIO_MODE_MAPPED
while there, change vendor string to TNF since X.org had nothing to do with
this driver

include <sys/ioctl.h> for ioctl()
WTF? Fix pasto calling function from a different driver!?!

apply some #if GET_ABI_MAJOR(ABI_VIDEODRV_VERSION) < 6 around the code
that uses features no longer part of xorg-server 1.9.

seems to fix sgimips builds.

fix the previous - use GET_ABI_MAJOR(ABI_VIDEODRV_VERSION) > 6.

copy a hack from the vmware driver, and avoid using xf86LoaderReqSymLists()
and LoaderRefSymLists() in xorg-server >= 1.7.

remove debug spam

make C -configure work with the crime driver

clean up debugging code, while there:
- use a fake framebuffer like newport does to hide software rendering
artifacts
- only map the framebuffer when debugging, and actually unmap it too

make this compile in the New Order Of Things

Now this driver actually works.
