Move the core logic used to replay commits into "libgit.a" so that it can be easily reused by other commands. It will be used in a subsequent commit where we're about to introduce a new git-history(1) command. Note that with this change we have no sign-comparison warnings anymore, and neither do we depend on `the_repository`.
