bisect--helper: reimplement `bisect_log` shell function in C
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.
