Add NetBSD keyword.

Revert r1.4.
The changes are minimal and they cause redraw problems (as reported by
Maxim Devaev on port-sparc).

more xf86RamDac.h vs xf86Cursor.h.

Add some acceleration using the P9100 quad and blit commands:
- for solid fill (quad)
- for pixmap copy (blit) when source and destination pitch are the same

Don't nest comments.

Don't define MaxClip and junk twice, fixing build with -fno-common.

Add support for EXA, so that the pnozz driver works again with Xorg.
Note, that only minimal acceleration is currently supported.

Thanks to macallan for the pointers to get this working.

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.

#include <sys/ioctl.h>

fix the function name.

apply some GET_ABI_MAJOR() and avoid compile errors

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.
