This commit is two backports squashed into one to avoid regressions. python: *really* remove get_event_loop A prior commit, aa1ff990, switched away from using get_event_loop *by default*, but this is not good enough to avoid deprecation warnings as `asyncio.get_event_loop_policy().get_event_loop()` is *also* deprecated. Replace this mechanism with explicit calls to asyncio.get_new_loop() and revise the cleanup mechanisms in __del__ to match. python: avoid creating additional event loops per thread "Too hasty by far!", commit 21ce2ee4 attempted to avoid deprecated behavior altogether by calling new_event_loop() directly if there was no loop currently running, but this has the unfortunate side effect of potentially creating multiple event loops per thread if tests instantiate multiple QMP connections in a single thread. This behavior is apparently not well-defined and causes problems in some, but not all, combinations of Python interpreter version and platform environment. Partially revert to Daniel Berrange's original patch, which calls get_event_loop and simply suppresses the deprecation warning in Python<=3.13. This time, however, additionally register new loops created with new_event_loop() so that future calls to get_event_loop() will return the loop already created. Reported-by: Richard W.M.
