If we don't recognize the PCI ID, we can't reasonably load the driver.
However, calling abort() is quite rude - it means the application that

glsl: Add locking to builtin_builder singleton

Consider a multithreaded program with two contexts A and B, and the
following scenario:

1. Context A calls initialize(), which allocates mem_ctx and starts
   building built-ins.
2. Context B calls initialize(), which sees mem_ctx != NULL and assumes
   everything is already set up.  It returns.
3. Context B calls find(), which fails to find the built-in since it
   hasn't been created yet.
4. Context A finally finishes initializing the built-ins.

This will break at step 3.  Adding a lock ensures that subsequent
callers of initialize() will wait until initialization is actually
complete.

Similarly, if any thread calls release while another thread is still
initializing, or calling find(), the mem_ctx/shader would get free'd while
from under it, leading to corruption or use-after-free crashes.

Fixes sporadic failures in Piglit's glx-multithread-shader-compile.

glx: Pass NULL DRI drawables into the DRI driver for None GLX drawables

GLX_ARB_create_context allows making a GLX context current with None
drawable and readables, but this was never implemented correctly in GLX.
We would create a __DRIdrawable for the None GLX drawable and pass that
to the DRI driver and that would somehow work.  Now it's somehow broken.

The way this should have worked is that we pass a NULL DRI drawable
to the DRI driver when the GLX user calls glXMakeContextCurrent()
with None for drawable and readables.

vdpau: flush the context before exporting the surface v2

Bugzilla (bug needs XBMC changes as well):
https://bugs.freedesktop.org/show_bug.cgi?id=73191

When VL uploads vertex buffers, it uses PIPE_TRANSFER_DONTBLOCK, which always
flushes the context in the winsys if the buffer being mapped is busy. Since
I added handling of DISCARD_RANGE, DONTBLOCK has had no effect when combined
with DISCARD_RANGE and I think the context isn't flushed anywhere else,
so no commands are submitted to the GPU until the IB is full, which takes
a lot of frames.

Using DISCARD_RANGE is not the only way to trigger this bug. The other way
is to reallocate the vertex buffer before every upload.

BTW, I'm not sure if this is the right place for flushing, but it does fix
the bug.

v2 (chk): move the flush to the right place.
