Allen Webb 5e185834fc sys_util: Add scoped_signal_handler. ... This adds a scoped signal handler struct that performs some basic checks to avoid accidental replacement of an existing handler and cleanup when the handler goes out of scope. Also, adds scoped_signal_handler::wait_for_interrupt() which blocks until SIGINT is received (e.g. via Ctrl-C).
