[RFC PATCH v2 1/2] bisect: split out replay file parsing

[Adam Dinwoodie <adam@dinwoodie.org>]

In order to allow a git bisect log file to be replayed without using all
the surrounding code to do things like clean the repository state, split
out the file-parsing part of bisect_replay into a separate function.
