gallium: add flag PIPE_TRANSFER_MAP_PERMANENTLY
Please see the diff for further info. This paves the way for moving user buffer uploads out of drivers and should allow to clean up the mess in u_upload_mgr in the meantime. For now only allowed for buffers on r300 and r600. Acked-by: Christian König <[email protected]>
