src,lib: make ^C print a JS stack trace

If terminating the process with ctrl-c / SIGINT, prints a JS stacktrace
leading up to the currently executing code.

The feature would be enabled under option `--trace-sigint`.

Conditions of no stacktrace on sigint:

- has (an) active sigint listener(s);
- main thread is idle (i.e. uv polling), a message instead of stacktrace
  would be printed.
