[Mesa-dev] [PATCH 13/13] mesa: Support more glGet enums for ES3

[Matt Turner]

From: Chad Versace <chad.versace at linux.intel.com>

For glGetIntegerv, add support for the following in an OpenGL ES 3.0
context:
    GL_MAJOR_VERSION
    GL_MINOR_VERSION
    GL_NUM_EXTENSIONS

See Table 6.29 of the OpenGL ES 3.0 spec.

Fixes error GL_INVALID_ENUM in piglit egl-create-context-verify-gl-flavor,
testcase for OpenGL ES 3.0.
