mesa/es: Add OpenGL ES overlay.
This is primitive support for OpenGL ES. It uses a subset of mesa sources to build libesXgallium.a and libesXapi.a, where X is 1 for OpenGL ES 1.x, 2 for OpenGL ES 2.x. The static libraries serve the same purpose as libmesagallium.a and libglapi.a do for OpenGL. This is based on the work of opengl-es branch. Signed-off-by: Chia-I Wu <olvaffe@gmail.com>
