wayland: Destroy frame callback when destroying surface

If a frame callback is not destroyed when destroying a surface, its
handler function will be invoked if the surface was destroyed after the
callback was requested but before it was invoked, causing a write on
free:ed memory.

This can happen if eglDestroySurface() is called shortly after
eglSwapBuffers().

Note: This is a candidate for stable branches.

glsl_to_tgsi: fix dst register for texturing fetches.

I've no idea why there isn't a piglit that triggers this behaviour,
but while enabling TBOs for softpipe and r600g, I noticed all the
integer tests failed. I tracked it back to the TXF returning a float
when it should be returning an int. This fixed it and I haven't
seen any regressions in a full piglit run on softpipe.

i965/fs: Add support for global copy propagation.

It is common for complicated shaders, particularly code-generated ones, to
have a big array of uniforms or attributes, and a prologue in the shader that
dereferences from the big array to more informatively-named local variables.
Then there will be some small control flow operation (like a ? : statement),
and then use of those informatively-named variables.  We were emitting extra
MOVs in these cases, because copy propagation couldn't reach across control
flow.

Instead, implement dataflow analysis on the output of the first copy
propagation pass and re-run it to propagate those extra MOVs out.

On one future Steam release, reduces VS+FS instruction count from 42837 to
41437.  No statistically significant performance difference (n=48), though, at
least at the low resolution I'm running it at.

shader-db results:

total instructions in shared programs: 722170 -> 702545 (-2.72%)
instructions in affected programs:     260618 -> 240993 (-7.53%)

Some shaders do get hurt by up to 2 instructions, because a choice to copy
propagate instead of coalesce or something like that results in a dead write
sticking around.  Given that we already have instances of those instructions
in the affected programs (particularly unigine), we should just improve dead
code elimination to fix the problem.
i965: Fix slow leak of brw->wm.compile_data->store

We were successfully freeing our compile data at context destroy, but until
then we were allocating a new store every compile without freeing it.

r600g: clarify const buffer numbering and handling

For cube map arrays I'll need another driver private constant
buffer, and looking forward to UBOs. So clean up with some
defines, that can be modified when adding cube map array and ubos
later.

r600g: fix lod bias/explicit lod with cube maps.

While developing cube map array support I found that we didn't

I've submitted a test to piglit to check for this, and this
fixes explicit lod and lod bias with cube maps.

gallium: add defines/shader opcode for texture cube map array

This just adds the texture target and capability along
with 3 new opcodes required to support this extension.

As this extension requires some texture opcodes with samp + 5 args,
we need to use another src register, this is only required
for TEX, TXL and TXB opcodes to implement this spec.

TEX2 is required for shadow cube map arrays
TXL2 is required for cube map array sampler + explicit lod
TXB2 is required for cube map array sampler + lod bias
