I keep qemu VM event loop exiting synchronously but add code to avoid deadlock that can be caused by this approach. I guess it is worth having synchronous exiting of threads in this case to avoid crashes.
Patches that are already positively reviewed has appropriate 'Reviewed-by' lines.
Changes from v1: - rename stateShutdown to state stateShutdownPrepare - introduce net daemon shutdown callbacks - make some adjustments in terms of qemu per VM's event loop thread finishing - factor out net server shutdown facilities into distinct patch - increase shutdown timeout from 15s to 30s
