The Android EGL shim injects GL_EXT_debug_marker into the ES driver
EXTENSIONS string for the OpenGL ES 1.x and 2.0/3.0/3.1 drivers if
the extension is not already provided. This feature is used by
GLES_trace.
In Open GL ES 3.0 it became possible to query an indexed version of
the EXTENSIONS string via GetStringi(). NUM_EXTENSIONS Gets were
also added to the specification (taken from Open GL).
If the shim does not have to inject the extension, then there is no
problem, as glGetString() and glGetStringi() / NUM_EXTENSIONS will
be consistent. However, if the Android EGL shim injects the
extension, NUM_EXTENSIONS and GetStringi() will report one less
extension than is really available.
Consistency between these methods is tested by the dEQP framework
with the dEQP-GLES3.functional.state_query.string.extensions test.
If the driver does not provide GL_EXT_debug_marker, this test
fails.
This change wraps all of the affected entry points so that the
wrapped driver extensions are never visible directly to dEQP,
eliminating the inconsistency.
Enable ES 3.1 generation in glgen.py, and regenerate everything to add
support for that as well as these new extensions in the registry:
- EXT_copy_image
- EXT_draw_buffers_indexed
- EXT_geometry_shader
- EXT_gpu_shader5
- EXT_primitive_bounding_box
- EXT_shader_implicit_conversions
- EXT_shader_io_blocks
- EXT_tessellation_shader
- EXT_texture_border_clamp
- EXT_texture_buffer
- EXT_texture_cube_map_array
- EXT_texture_view

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)

We weren't using gl2_api.in, since gl3_api.in was a superset. And
gl3ext_api.in was empty, and Khronos has decided to keep it that way
(any GLES2/3/... extensions will be in gl2ext.h).
Since libGLES2.so will have all future backwards-compatible GLES APIs,
it makes sense to just use gl2_api.in and gl2ext_api.in to build its
contents. This changes renames gl3_api.in to gl2_api.in and updates
uses of it, and removes gl3ext_api.in and references.

This change has been made in Khronos SVN for GLES2 already, however it
is mildly controversial and discussion is on-going.
This change is necessary for Android because otherwise applications
cannot include both GLES2/gl2.h and GLES3/gl3.h as the glShaderSource()
prototype mismatches. Native programs may include framework headers
(which now include GLES3 headers only) but already have included GLES2
headers, creating an incompatibility.

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.
