Split gl_renderer_setup into two functions

Browse Source 
Part of the gl_renderer_setup function only deals with checking EGL
extensions and doesn't need to have a current context. This patch
moves these checks so that they are done during gl_renderer_create
instead of waiting until we have an output. We will need this in a
later patch because some of the EGL extensions will affect how we
create the EGLSurface.
