When users are inserting new objects into the stream, we cannot make as
many assumptions and need to do more careful checks for whether commits
become empty or not.

There are a number of things not present in "normal" imports that we
nevertheless support and need to be tested:
* broken timezone adjustment (+051800->+0261; observed in the wild
in real repos, and adjustment prevents fast-import from dying)
* commits missing an author (observed in the wild in a real repo;
just sets author to committer)
* optional additional linefeeds in the input allowed by
git-fast-import but usually not written by git-fast-export
* progress and checkpoint objects
* progress, checkpoint, and 'everything' callbacks

Python wants filenames with underscores instead of hyphens and with a
.py extension. We really want the main file named git-filter-repo, but
we can add a git_filter_repo.py symlink. Doing so dramatically
simplifies the steps needed to import it as a library in external python
scripts.
