i965: Don't call abort() on an unknown device.

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
tried to initialize us (possibly the X server) can't continue via
fallback paths.  We already have a more polite mechanism - failing to
create the context.  So, just use that.

While we're at it, improve the error message.

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.

i965/fs: Simplify FS_OPCODE_SET_OMASK stride mashing a bit.

In the first case, we can simply call stride(mask, 16, 8, 2) rather than
creating a new register with a different stride, then immediately
changing it a second time.

In the second case, the stride was already what we wanted, so we can
just use mask without any changes at all.

mesa: Fix MESA_FORMAT_Z24_UNORM_S8_UINT vs. X8_UINT mix-up.

In commit eeed49f5f290793870c60b5b635b977a732a1eb4, Mark accidentally
renamed MESA_FORMAT_S8_Z24 to MESA_FORMAT_Z24_UNORM_X8_UINT and
MESA_FORMAT_X8_Z24 to MESA_FORMAT_Z24_UNORM_S8_UINT, reversing their
sense.  The commit message was correct, but what sed commands actually
got run didn't match that.

This patch swaps the two enum names, reversing them.  This should undo
the damage, but might break things if people have manually fixed a few
instances in the meantime...

Mark's commit also failed to mention renames:
s/MESA_FORMAT_ARGB2101010_UINT\b/MESA_FORMAT_B10G10R10A2_UINT/g
s/MESA_FORMAT_ABGR2101010\b/MESA_FORMAT_R10G10B10A2_UNORM/g
but those seem okay.
