Subject: 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.
