    gallium: fix some render to texture bugs
    
    Before, we were sometimes rendering into a stale texture because
    st_finalize_texture() would discard the old texture and create a new one.
    
    Moved st_update_framebuffer atom after texture validation so that we
    can create a new renderbuffer surface if the texture changes.
    
    Also, split texture validation into two parts: finalize_textures and
    update_textures.  Do finalize_textures first to avoid getting into the
    situtation where we're doing a pipe->surface_copy() mid-way through
    state validation.
    
    Some debug code still in place, but disabled...

    mesa: add texturing to thread test
    
    Run with -t to enable texture mapping.
    Press 't' to update the texture image.  When the texture is changed in one
    thread it should also get updated in the other threads since textures are
    shared by all contexts.
