Subject: [PATCH 1/4] configure.ac: Add check for epoxy

Add a check for epoxy support (optional) so that we can use it instead
of libGL in eglinfo to create GLES contexts.

Subject: [PATCH 2/4] eglinfo: Use epoxy if available

If epoxy is available, use it instead of EGL directly.

The benefit if epoxy is that it will dlopen the EGL libs for
us automatically, which will come handy when we'll need to create
contexts.
