signal_handler_unregister() calls sigaction() with uninitializing sa_flags in the struct sigaction. Make sure sa_flags is always initialized in signal_handler_unregister() by initializing the struct sigaction when declaring it. Also add the initialization to signal_handler_register() even if there are no know bugs in there because correctness is then obvious from the code itself.
