mesa: fix maximum allowed proxy texture size condition
width, height parameter in glTexImage2D() includes: texture image
width + 2 * border (if any). So when doing the texture size check
in _mesa_test_proxy_teximage() width and height should not exceed
maximum supported size for target texture type + 2 * border.
i.e. 1 << (ctx->Const.MaxTextureLevels - 1) + 2 * border
Texture border is anyway stripped out before it is given to intel
or gallium drivers.
This patch fixes Intel oglconform test case:
max_values negative.textureSize.textureCube
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=44970
Note: This is a candidate for mesa 8.0 branch.

NOTE: Compared to ff2497d this does not install the default drirc.
The pre-automake build system is sufficiently braindamaged to make
this exceptionally difficult.

commit 728bda08d85813eeda12ae52e0893a37533ba02c
Author: Eric Anholt <e...@anholt.net>
Date: Sat Jan 28 11:43:22 2012 -0800
glsl: Throw the required error when a case label is a non-constant.
It's not quite spelled out in the spec text, but the grammar indicates
that only constant values are allowed as switch() case labels (and
only constant values make sense, anyway).
Fixes piglit
glsl-1.30/compiler/switch-statement/switch-case-uniform-int.vert.
NOTE: This is a candidate for the 8.0 branch.

glsl: Save and restore the whole switch state for nesting.
This stuffs them all in a struct for sanity. Fixes piglit
