This series extends the iou-zcrx selftests to be multithreaded while preserving existing single-threaded tests.
Patches 1 and 2 are prep fixes/cleanups. Patch 3 refactors the server's global state. Patches 4 and 5 add the multithreaded client and server. Finally, patch 6 adds the python side multithreaded test case.
