block: Make more BlockDriver definitions static

Most block driver implementations don't have any reason for their BlockDriver to be public. The only exceptions are bdrv_file, bdrv_raw and bdrv_qcow2, which are actually used in other source files. Make all other BlockDriver definitions static if they aren't yet.
