It's not very usable since in the rare, but definitely existing case that
we don't have a current context, it will return NULL.
Presumably it will always be safe to use the dri screen the drawable was
created with for operations on that drawable.

Having two callbacks to manage a single int seems like an overkill.
Use a cached copy and update that when needed.

This implements a wait for glXWaitGL, glXCopySubBuffer, dri flush_front and
creation of fake front until all pending SwapBuffers have been committed to
hardware. Among other things this fixes piglit glx-copy-sub-buffers on dri3.

As of last commit, no invalid swap interval can be stored, so there's
no need to sanitize the values when reading them anymore.

If the application hasn't done any drawing since the last call, we
would reuse the same back buffer which was used for the previous swap,
which may not have completed yet. This could result in various issues
such as tearing or application hangs.
In the normal case, the behaviour is unchanged.

This is a DRI3 version of a change made for DRI2
(4d6d4f939e, "egl/dri2: implement query surface hook"),
that fixed failures in dEQP-EGL.functional.resize.surface_size.grow
and dEQP-EGL.functional.resize.surface_size.shrink.

This tries to mirrors the codepath taken by DRI2 in IntelSetTexBuffer2()
and fixes many applications when using DRI3:
- Totem with libva on hw-accelerated decoding
- obs-studio, using Window Capture (Xcomposite) as a Source
- gstreamer with VAAPI
v2:
- introduce get_dri_screen() in the dri3 loader's vtable (krh)

Always use 3 buffers when flipping. With only 2 buffers, we have to wait
for a flip to complete (which takes non-0 time even with asynchronous
flips) before we can start working on the next frame. We were previously
only using 2 buffers for flipping if the X server supports asynchronous
flips, even when we're not using asynchronous flips. This could result
in bad performance (the referenced bug report is an extreme case, where
the inter-frame stalls were preventing the GPU from reaching its maximum
clocks).
I couldn't measure any performance boost using 4 buffers with flipping.
Performance actually seemed to go down slightly, but that might have
been just noise.
Without flipping, a single back buffer is enough for swap interval 0,
but we need to use 2 back buffers when the swap interval is non-0,
otherwise we have to wait for the swap interval to pass before we can
start working on the next frame. This condition was previously reversed.

Without this, the X server may accumulate stale Present event contexts
if a client ends up creating and destroying DRI drawables for the same
window.
v2: Based on Chris Wilson's review:
* Use xcb_present_select_input_checked so that protocol errors
generated by old X servers can be handled gracefully
* Use xcb_discard_reply() instead of free(xcb_request_check())
Used to support EGL_KHR_image_pixmap.
