    gallium: fix some surface usage bugs
    
    When a surface is created with GPU_WRITE that really means "GPU render"
    and that can involve reads (blending).  Set surface usage to
    PIPE_BUFFER_USAGE_CPU_READ + WRITE.  Fixes progs/demos/lodbias demo.
    
    Also, mark texture as 'modified' when mapped for writing so that the tile
    cache can know when to freshen a cached tile.  Fixes glTexSubImage2D().
