[Mesa-dev] [PATCH 1/4] mesa: Make more consistent use of _mesa_is_{user, winsys}_fbo()

A lot of code was still differentiating between between winsys and
user fbos by testing the fbo's name against zero. This converts
everything in core mesa, the state tracker, and src/mesa/program over
to use _mesa_is_user_fbo() and _mesa_is_winsys_fbo().
