Use "unsigned int" instead of GLenum and GLuint, so we don't depend on
these types from opengl headers.  Drop all CONFIG_OPENGL #ifdefs from
console.h

ui/sdl2.h is included by ui/sdl2.c, ui/sdl2-2d.c, ui/sdl2-gl.c and
ui/sdl2-input.c, but none of those are compiled with OPENGL_CFLAGS
so this won't work if epoxy/gl.h isn't on the default include path,
I think.
