v7:
01: A complete reversion of the commit c624b015bf14f "block/stream:
introduce a bottom node" doesn't make a sense as the patch
"stream: Deal with filters" replaces the concept of the
'bottom node' with the one of the 'base_overlay' and the
'above_base', introduced by Max in the series "block: Deal with
filters".
02: #include "block/block-copy.h" was removed.
The extra "state->active = true" was dropped.
The comment about the bdrv_child_refresh_perms() supplied.
03: "filter_node_name = NULL" dropped in the qmp_block_stream().
04: The comment to the commit was extended with an explanation of
why the test case 'test_stream_parallel' was removed.
Due to the v6 review, the initial "char *base_fmt" is kept for
the final backing file change no more. I urge to keep it.
