Series updated with feedback from Ian. New tests added. The patches
are available in
http://cgit.freedesktop.org/~mattst88/piglit/log/?h=egl_khr_create_context2

The only test that fails is the invalid flag GL test, which
incorrectly creates contexts with bad flags. The GLES version of the
tests passes though.
