Also add a subcommand `--bisect-autostart` to `git bisect--helper` be called from `bisect_state()` from git-bisect.sh . Using `--bisect-autostart` subcommand is a temporary measure to port shell function to C so as to use the existing test suite. As more functions are ported, this subcommand will be retired and bisect_autostart() will be called directly by `bisect_state()`.
