* OpenVPN's main init-run-cleanup loop.

* - Outer loop, run at startup and then once per \c SIGHUP:
* - Level 1 initialization
* - Inner loop, run at startup and then once per \c SIGUSR1:
* - Call event loop function depending on client or server mode:
* - \c tunnel_point_to_point()
* - \c tunnel_server()
* - Level 1 cleanup
* - Once-per-process cleanup.
*
* @param argc - Commandline argument count.
* @param argv - Commandline argument values.
