There was no explicit support for x86/64 architecture in EGL/GLES wrappers.
This resulted either in failures or sub-optimal implementation of the wrapper functions.

Import GLES headers from Khronos SVN r26322:
https://cvs.khronos.org/svn/repos/registry/trunk/public/gles/api
There are many non-functional whitespace and parameter name changes
included here. These were introduced upstream when converting from the
old .spec registry to the new XML registry.
There are also some new extensions added. Unfortunately there isn't a
version of the XML that matches the headers the previous versions of
the *.in files were generated from, so I can't separate out the
non-functional changes from the new extensions (other than temporarily
hacking them out of the XML). See below for a list.
Finally, I had to hack the official glext.h. Khronos hasn't updated
the official GLES1 headers since switching to the XML registry, and
there is one critical difference: a "const void**" parameter in the
official header is "const void* const*" in the registry. I changed the
header to avoid build errors with code generated from the registry.
Dependencies on the *.in files required manually updating some
GLES_trace/ files as well:
- gltrace_api.{h,cpp} must be manually re-generated using
tools/genapi.py.
- New GL prototypes must be manually added to gltrace.proto.
- gltrace.pb.{h,cpp} must be regenerated using aprotoc (see dev.make)

in the common case this saves one instructions per jump
(which will help with the i-cache).
this change also gets rid of the "use slow tls" option,
which was useless. So at least now architectures that don't have
assembly bindings will perform much better.

this simplify our EGL wrapper implementation a lot.
This wrapping is no longer needed now that we can only
support a single underlaying EGL implementation.

This extension is always added to the GL_EXTENSIONS
extension string for the current GL context, regardless
of if it's supported by the h/w driver.
The extension itself will be handled by GLES_trace (eventually),
when GLES_trace is not enabled, it'll result to a no-op.
If the h/w implementation has this extension, we'll call that version
instead of our dummy version.

it turns out that we cannot return INVALID_OPERATION from glGetError() because the
GL spec says that it must be called in a loop until it returns GL_NO_ERROR.
now, we always return 0 from GL functions called from a thread with no
context bound. This means that glGetError() will return NO_ERROR in this case,
which is better than returning a random value (which could trap the app in a loop).
if this happens in the main thread of a process, we LOG an error message once.

glEGLImageTargetRenderbufferOES() pass the wrapped EGLImage
to the implementation, rather than the unwrapped one.

Adds support for formerly-unimplemented methods:
glCurrentPaletteMatrixOES
glLoadPaletteFromModelViewMatrixOES
glMatrixIndexPointerOES
glWeightPointerOES
The bulk of the changes are related to implementing the two PointerOES
methods, which are implemented pretty much the same way as the existing
Pointer methods were implemented.
This change also changes the way glPointSizePointerOES is implemented,
making it act like all the other Pointer methods. (Previously it was
not handling non-direct-buffer arguments correctly.)
Fixes bug 2308625 "Support matrix palette skinning
in JSR239 and related APIs"
Also updated GLLogWraper to fix two bugs in GLLogWrapper that were
discovered while testing matrix palette skinning support:
a) Handle trying to print the contents of null-but-enabled buffers.
(It's not legal to draw with null-but-enabled buffers, and
in fact some OpenGL drivers will crash if you try to render in this
state, but there's no reason the GLLogWrapper should crash while trying
to debug this situation.
b) Don't read off the end of a vertex buffer with non-zero position when
printing the entire contents of the vertex buffer. Now we only print from
the current position to the end of the buffer.
Instead of using a different function pointer table for ES 1.x and ES 2.x,
we use a single one that is the union (sort|uniq) of both tables. Two
instances of this table are initialized with pointers to GL ES 1.x and GL ES 2.x
entry-points.
When a context is created, we store its version number and when it is bound to a
thread we set the approruiate table based on the stored version.
This introduce no penalty while dispatching gl calls to the right API version.
