merge xf86-video-nouveau 1.0.18

initial import of xf86-video-nouveau-1.0.18

more xf86SetModeDefaultName( after xf86CVTMode()

various updates to build against xorg-server 21.1.3.

- avoid a const issue with an expanded __UNCONST().
- cope with renamed member names
- deal with "xf86RamDac.h" going away (now use "xf86Cursor.h")

merge xf86-video-nouveau 1.0.17 and xprop 1.2.5.

initial import of xf86-video-nouveau-1.0.17

put drmmode_udev_notify() under HAVE_LIBUDEV.

merge xf86-video-nouveau 1.0.16.

initial import of xf86-video-nouveau-1.0.16

Put all the ugly include order dependent stuff in a separate file
and arrange for that to be included first where needed.

Explicitly include the headers in the right sequence to make the magic happen,
explaining why.

Use _XTYPEDEF_POINTER directly to determine if the typedef is available.

fix various errors and warnings with xorg-server 1.20:

- no Error() in scope
- more wakeup/blockhandler ABI changes
- more notify fd API changes
- more xf86CursorResetCursor changes
- lots of char* -> const char*
- fix ati kms config.h now HAVE_XF86_CURSOR_RESET_CURSOR is available
- another xf86GetOS() is removed fix
- OsBlockSIGIO() etc, -> old, but still around API until properly converted
- don't free const char * data owned by some other system

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

various updates for xorg-server 1.20. some of these are work-in-progress,
the xsrc build is broken for most ports currently.

- xf86DisableRandR() is gone
- use HAVE_NOTIFY_FD like other modern drivers in compat-api.h
- pRotatedPixmap is done
- some PixmanPtr is now DrawablePtr (this one is all over problem with many
consumers, and perhaps the major breakage point currently.)
