[Qemu-block] [PATCH v2 00/10] iotests: Fix some issues

[Max Reitz]

A couple of iotests for not-so-common formats/protocols are broken for
me, so this series fixes them.

The last patch in this series is not required, but it seemed like a good
thing to do to me.


There are more issues, but those should be fixed separately (and these
are only the ones I know of):
- 093 and 136 are flaky if the system is under load, I’ve reported this
  to Berto, and he seems to be working on it O:-)

- I’ve seen aborts in 169; Vladimir has sent patches for this, I’m just
  not sure yet who’s going to take them (the iotest patch is good, the
  QMP patch, well, is a QMP patch, so it isn’t my immediate territorry)

- 129 is broken because it uses BB throttling underneath block jobs;
  unfortunately at least the mirror job completely ignores that
  throttling (and has done so for a while), so we need to get something
  working with a filter node there.  But that’s not so easy, for a
  couple of reasons:
  (1) The commit job doesn’t work with that right now because it cannot
      deal with such a filter in the commit chain (I have to look at
      this in the context of my “Deal with filters” series)
  (2) Also, such a change results in a failed assertion:
      http://lists.nongnu.org/archive/html/qemu-block/2019-01/msg01006.html

Finally, note that tcp_chr_disconnect() has a bit of a problem with
running concurrently, so that causes tests to fail, too:

v2:
- Added a note to patch 1 that even with this patch, 237 will fail on
  Python 2.x [John]
- Put patch 5 (which fixes that) right after patch 1 [John]
- Added a note to patch 2 (which used to be patch 5) on what the exact
  issue is [John]
- Patch 6: Dropped the test for “bytes”, because you cannot use such
  objects like normal strings anyway [John?]
- Patch 9: Added
