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.

merge i740 1.3.5, newport 0.2.4 and tdfx 1.4.6.

initial import of xf86-video-newport-0.2.4

don't bail if the video mode is something else than 1280x1024
1024x768 works fine

add unistd for close.

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.

make this work in the New Order Of Things(tm):
- make Xorg -configure work again
- fix the DCB timing when talking to XMAP9 to the values used by the kernel,
now colours look right on my Indy and all the randomness when starting
X is gone

make this compile with new Xorg

in 24bit write a linear colour map into the DAC.
Now colours look right.

Still needs testing in 8 bit.

Add NetBSD-specific bits. Now this driver works on my R5k Indy with 24bit
Newport graphics board.

Xorg's driver for Newport / NG1 graphics boards found in SGI Indy and others.
