Multiple item params are OK because we don't allow swizzles for them
(in case you do array access to hit their elements, for example). For
singles, though, using the swizzle can cut down on storage, we do want
to allow a swizzled use of another param.
Fixes OGLC texRect.c.

The pixel transfer rules state that we must set alpha to 1.0 in this case
which we can't easily do with the blitter. We can do to passes: one that
sets the alpha to 0xff and one that copies the RGB bits or we can just
use the 3D engine. Neither approach seems worth it for this case.

Commit 5d0e136eff54a34258b5adaeda4cb267831e8234 exposed a long-standing
bug in the glGetUniform*() code paths. We weren't properly decoding
the location parameter.
Fixes fd.o bug/regression 28344
Note: this patch should go into the 7.8 branch after the above-mentioned
commit.

This adds TFP support to the swrast driver, with this I can run gnome-shell inside Xephyr slowly. I've no idea why I did it, and g-s has other rendering issues under swrast, but it might be useful to hook up llvmpipe later. I've no idea if I even want to commit it at this point.
An enhanced version might just pass the pointer in the indirect rendering case
and avoid the memcpy.

This fixes an uninitialised value use in the dri2 st when doing TFP.
It uses the driContextPriv which isn't initialised at alloc time.

Fixes the assert (and buffer overrun):
glknots: intel_batchbuffer.c:164: _intel_batchbuffer_flush: Assertion
'used >= batch->buf->size' failed.

eglplatform.h no longer defines int32_t.

Those macros used by _mesa_init_shader_dispatch are not available when
FEATURE_GL is not defined.

This lets Mesa work like other OpenGL implementations with regard
to indexing uniform arrays. See comments for details.
Note: this is a candidate for the 7.8 branch.

Both softpipe and llvmpipe pass the piglit half float test.

We want to check the incoming renderbuffer format, not the (potentially
non-existant) current attachment.
Fixes segfault w/ fbotexture -ds2.
NOTE: this will be applied to the 7.8 branch too.

When generating or uploading a new (higher) mipmap level for an image,
we can need to allocate a miptree for a level greater than
texObj->MaxLevel.

This can happen when checking if a software fallback for a higher level
operation (such as GenerateMipmap) is needed.

We could potentially do this on G45 as well, though the units are
different. On 965, the timestamp is tied to hclk, which would make
supporting it harder.

This is a workaround for Ironlake errata. The emit_mi_flush is used
for a few purposes:
1) Flushing write caches for RTT (including blit to texture)
2) Pipe fencing for sync objects
3) Spamming cache flushes to track down cache flush bugs
Spamming cache flushes seems less important than following the docs,
and we should probably do that with a different mechanism than the one
for render cache flushes.

The es1 and es2 dispath table initialization code is generated from the
API XML files and we can't easily share the dispatch table code setup.
Keep the _mesa_init_shader_dispatch() part of the patch, but roll back
the static-ization of shader entrypoints so es1 and es2 dispatch
initialization still works.

Refactor the code for all the glGetVertexAttrib() functions.
