replay: add helper to put entry into mapped_commits

The function replay_revisions() in replay.c is rather lengthy. Extract
the logic to put a commit entry into mapped_commits into a helper
function put_mapped_commit().

While at it, rename mapped_commit() to get_mapped_commit() to pair with
this new function.
