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

merge xf86-video-amdgpu-1.3.0, xf86-video-ati-7.9.0,
xf86-video-nouveau-1.0.15, and xf86-video-openchrome-0.6.0.

Since CARD32 and uint32_t don't necessarily use the same underlaying
type, e.g. on i386, add an explicit cast as well.

Fix format strings.
