Reimplement the `bisect_log` shell function in C and also add `--bisect-log` subcommand to `git bisect--helper` to call it from git-bisect.sh .
Using `--bisect-log` 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 will be called by some other method.
