Hi all!

I decided to post v14 myself, to show how to keep the test with parallel
stream jobs.

So, main addition in v14 is "bottom" argument for stream job. Next week
I'll send a follow-up with deprecation for old "base" API.

Also, I already finished my work on updating permissions, so that we
don't need ".active"-like things to add/drop filters, still, as v14 is
a lot bigger than v2, and I believe this this v14 is closer to be
merged, so I'd better resend my
  "[PATCH v2 00/36] block: update graph permissions update", basing on
this v14 (and reworking filter drop/remove).

05: fix bdrv_is_allocated_above() usage
09: merge change from further commit which uses unfiltered_bs for bdrv_find_backing_image
10: new
11: new
12: new, splitted from last commit to simplify it a bit
13: - pass bottom option to filter always (who know, may be base will appear during the job)
    - keep test test_stream_parallel in 30 iotest
    - rework changes in 245 iotest
