Instead of buffering the test output into a StringIO, patch it on
the fly by wrapping sys.stdout's write method. This can be
done unconditionally, even if using -d, which makes execute_unittest
a bit simpler.

The recent changes that brought RCU delayed device deletion,
broke few tests and this test breakage went unnoticed.
Fix this test by rewriting it in python
(which allows to wait for DEVICE_DELETED events before continuing).

This makes use of qdev_prop_drive_iothread for scsi-disk so that the
disk can be attached to a node that is already in the target AioContext.
We need to check that the HBA actually supports iothreads, otherwise
scsi-disk must make sure that the node is already in the main
AioContext.
This changes the error message for conflicting iothread settings.
Previously, virtio-scsi produced the error message, now it comes from
blk_set_aio_context(). Update a test case accordingly.

The NBD server uses an AioContext notifier, so it can tolerate that its
BlockBackend is switched to a different AioContext. Before we start
actually calling bdrv_try_set_aio_context(), which checks for
consistency, outside of test cases, we need to make sure that the NBD
server actually allows this.
