0a9415cf apparently can tickle bugs in the GL stack where glGetString
returns NULL, presumably because the eglMakeCurrent() didn't manage to
actually install a dispatch table and you're hitting a stub function.
That's clearly not our bug, but if it happens we should at least not
crash. Notice this case and fail gently.

It is currently (ab)using the screen BlockHandler callback to do
this. But this can cause problems with other extension as their
block handlers might have executed before Composite's. And the
operations Composite does might result in them wanting to change
timeouts.
Practically this caused problems for TigerVNC's VNC extension which
failed to send out updates for Composite's screen updates.
wl_drm's protocol "device" event provides the path to the DRM device,
which may not be a render node, thus causing Xwayland to fall back to
DRM authentication which may fail if the user has switched to another
VT while Xwayland is starting.
Search for a render node corresponding to the given DRM device and try
to use it instead, as render nodes do not need DRM authentication and
Xwayland can make use of them if it can find one.

These are so close to identical that most DDXes implement one in terms
of the other. All the relevant cases can be distinguished by the error
code, so merge the functions together to make things simpler.

st/dri: add drisw image extension
That's pretty cool, but it means glamor now thinks it can initialize on
llvmpipe. This is almost certainly not what anyone wants, as glamor on
llvmpipe is pretty much uniformly slower than fb.
This fixes both Xorg and Xwayland to refuse glamor in such a setup.
Xephyr is left alone, both because glamor is not the default there and
because Xephyr+glamor+llvmpipe is one of the easier ways to get xts to
exercise glamor.
The (very small) downside of this change is that you lose DRI3 support.
This wouldn't have helped you very much (since an lp glamor blit is
slower than a pixman blit), but it would eliminate the PutImage overhead
for llvmpipe's glXSwapBuffers. A future change should add DRI3 support
for the fb-only case.

Future work: To properly support GLX_ARB_create_context in indirect mode, we
need to use wglCreateContextAttribsARB() rather than wglCreateContext(),
when attribs are provided, rather than just dropping attribs on the floor,
as we currently do.
That probably entails removing the deferred context creation and instead
using a temporary window, as direct WGL does.

It seems for some drivers, wglChoosePixelFormatARB() can fail when the

DGAShutdown() walks every screen and attempts to reset the mode. That's
maybe a reasonable thing to do, although the explicit loop is certainly
a bad smell.
In ddxGiveUp it's called after we've torn down the vga arbiter - and in
fact most of the rest of screen state - which is... very very bad. The
other place it's called is from the Control-Alt-BackSpace handler, where
we don't even attempt to do vga arb setup, and where in any case we're
going to escape the main loop eventually anyway.
Move all that cleanup work inside DGACloseScreen. This means it happens
earlier in server teardown than previously, but not in a way you're ever
going to be upset about.
