initial import of xf86-video-ati-22.0.0

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")

fix a couple of issues found while testing new drm.

- actually check the return value of radeon_bo_open() in a three places
- for create_pixmap_for_fbcon(), release the bo when jumping to
'out_free_fb'. fixes memory leak.

Avoid multiple definitions of the same variable.

When adding an FB, don't assume that the front buffer is a radeon buffer
(it could be GBM managed instead).

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

avoid using GBM_BO_USE_LINEAR if it isn't defined.

cope with HAS_DIRTYTRACKING_ROTATION issues
