dri3 allows us to send handle of a texture directly to X
so this patch allows a state tracker to directly send its
texture to X to be used as back buffer and avoids extra
copying
v2: use clip width/height to display a portion of the surface
v3: remove redundant variables, fix wrapping, rename variables
handle vaapi path
v3.1: we need clip_width/height for every frame so we don't need
to maintain it for each buffer instead use a global variable
v4: In case of single gpu we can cache the buffers as applications
use constant number of buffer and we can avoid calls to present
extension for every frame

Andy & Leo did you guys already had a chance to test it? To me it looks
like this should work now.
Well there is still the tearing issue from loosing pageflips.
Maybe different GPUs don't see this. I can fix by forcing perf but I
just tested dal and it's not even fixable running that.
I guess that may not count as an issue with these patches as such if
xorg/xf86-video-amdgpu can work around, but it's a very noticeable
regression until that happens.
