merge xf86-video-tdfx 1.5.0.

initial import of xf86-video-tdfx-1.5.0

mostly fix amd64 xorg-server 1.20 builds:

- avoid bswap_16 etc defines for now. ends up with code-in-decl
- more ABI_VERSION 23 fixes (BlockHandler/WakeHandler) including re-fix
from previous
- more Notify API
- more shadowUpdatePackedWeak() removal
- remove fd_set handling from intel driver (part of ABI_VERSION 23)
- cope better with PixMap/Drawable separation in new server
- remove support for maxHValue and maxVValue (XXX?)
- hide drmmode_udev_notify() when not building udev
- comment out nouveau 'wfb' support, xorg-server 1.20 only supplies
either 'wfb' or 'fb' interface, not both, and we choose 'fb'
- define 'pointer' in nv_proto.h rather than relying upon Xdefs.h
- normalise the value of _XTYPEDEF_POINTER
- EGL is broken (missing) in xsrc currently
