qemu-iotests: do not buffer the test output 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.

iotests: Make 245 faster and more reliable Sometimes, 245 fails for me because some stream job has already finished while the test expects it to still be active. (With -c none, it fails basically every time.) The most reliable way to fix this is to simply set auto_finalize=false so the job will remain in the block graph as long as we need it. This allows us to drop the rate limiting, too, which makes the test faster. The only problem with this is that there is a single place that yields a different error message depending on whether the stream job is still copying data (so COR is enabled) or not (COR has been disabled, but the job still has the WRITE_UNCHANGED permission on the target node). We can easily address that by expecting either error message. Note that we do not need auto_finalize=false (or rate limiting) for the active commit job, because It never completes without an explicit block-job-complete anyway.

iotests: use python logging for iotests.log() We can turn logging on/off globally instead of per-function. Remove use_log from run_job, and use python logging to turn on diffable output when we run through a script entry point. iotest 245 changes output order due to buffering reasons. An extended note on python logging: A NullHandler is added to `qemu.iotests` to stop output from being generated if this code is used as a library without configuring logging. A NullHandler is only needed at the root, so a duplicate handler is not needed for `qemu.iotests.diff_io`. When logging is not configured, messages at the 'WARNING' levels or above are printed with default settings. The NullHandler stops this from occurring, which is considered good hygiene for code used as a library. See https://docs.python.org/3/howto/logging.html#library-config When logging is actually enabled (always at the behest of an explicit call by a client script), a root logger is implicitly created at the root, which allows messages to propagate upwards and be handled/emitted from the root logger with default settings. When we want iotest logging, we attach a handler to the qemu.iotests.diff_io logger and disable propagation to avoid possible double-printing. For more information on python logging infrastructure, I highly recommend downloading the pip package `logging_tree`, which provides convenient visualizations of the hierarchical logging configuration under different circumstances. See https://pypi.org/project/logging_tree/ for more information.
