The kernel can quite happily send a SIGBUS whenever we read from an bo
(due to oom), so catch it and handle it.

Instead track what we explicitly want to discard for the next operation,
so that we don't have to copy back the whole buffer if we have to
replace the shadow and intend to overwrite it all.

After a window resize or redirection, the DRI2BufferPtr become stale but
it may take a while for the Client to notice and reconfigure. Just
skip touching stale backbuffers and let the Client catch up.

We cannot simply compare against the crtc->shadow_bo for all our needs,
so pass in exactly the setup we want and apply that. In particular this
is required when flipping away from the single CRTC setup on secondary
pipes.

/usr/include/xorg/os.h around line 579 reads:

However strndup is already defined by glibc, and this redefine causes a
compile error.
This gets triggered because backlight.c does:

If we migrate the pixmap to the GPU, use the GPU bo. This may fix an issue
where we might end up using the CPU bo in a rare circumstance.

libdrm is a little lax and does not allocate sufficient space for us to

Unlike GLXWindows, GLXPixmaps are rendered directly into, without a
staging copy. Therefore we must treat those carefully when exported and
clear our hints everytime control passes back to the Client.

The region here has yet to be clipped, and so the only valid is-clipped
hint is from the flags computed from the PolyRect extents. Make sure we
use those when determining whether it is valid to discard damage.
