  iothread: include id in thread name

This makes it easier to find the desired thread.  Use "IO" plus the id;
even with the 14 character limit on the thread name, enough of the id should
be readable (e.g. "IO iothreadNNN" with three characters for the number).

  block: Don't wait serialising for non-COR read requests

The assertion problem was noticed in 06c3916b35a, but it wasn't
completely fixed, because even though the req is not marked as
serialising, it still gets serialised by wait_serialising_requests
against other serialising requests, which could lead to the same
assertion failure.

Fix it by even more explicitly skipping the serialising for this
specific case.

  iotests: Add regresion test case for write notifier assertion failure

The idea is to let the top level bs have a big request alignment with
blkdebug, so that the aio_write request issued from monitor will be
serialised. This tests that QEMU doesn't crash upon the read request
from the backup job's write notifier, which is a very special case of
"reentrant" request.
