Roll mesa 457812d9:9731cb9

This rolls to a version of our mesa library that does not have the
CL, GLES2, EGL or VG headers.  We should never use CL/VG headers, we
should always use GLES2 and EGL headers from khronos.

Here's a super belated follow up to the mesa GLES2 etc header deletion patch.  I
landed the patch to the mesa repo, this attempts to roll the DEPS.  May the
tryjobs be in our favor...

LGTM if it compiles. Looks like there are some remaining issues.

It's trying to build parts of mesa that implement some apis on top of gles1.
Pretty sure we don't use these, but it's hard to know for sure...

LGTM in principle (once it compiles)

[jamesr, 2014-09-27 20:39:36]

PS1 (pure roll) did not compile on windows and mac due to errors in the OpenGL
ES 1.0 conversion routines and the querymatrix implementation
(http://www.khronos.org/registry/gles/extensions/OES/OES_query_matrix.txt).  We
never use either of these, so PS2 simply excludes those files from the gyp
build.  This appears to be working fine according to the trybots.  It seems a
little dodgy to just remove these, but the es1 conversion stuff is definitely
never used and querymatrix when compiled in provides symbols that we do not
export any bindings to so I'm pretty sure it is safe.

PTAL just to be sure.

LGTM after the fact. It is difficult to figure out how to carve off unused
pieces of Mesa.
