C library defering selection of GL API and window system until runtime

Waffle is a C library that allows deferring the selection of GL API and window system until runtime. For example, on Linux, Waffle enables an application to select X11/EGL with an OpenGL 3.3 core profile, Wayland with OpenGL ES2, and other window system / API combinations. Waffle's immediate goal is to enable Piglit, Mesa's OpenGL test suite, to test multiple GL flavors.
