[PATCHv12 00/10] atomic pushes

There wasn't discussion within the last 24 hours and we were discussing only about minor changes. Changes compared to v9 (the last time I completely sent the series) is only found in the first 2 patches, where we had a back and forth about naming the method warn_if_skipped_connectivity_check and its behavior. I'm mainly sending this as a whole series, so Junio can pick it up easier as opposed to finding the latest version of each patch himself.

This patch series adds a flag to git push to update the remote refs atomically. This series applies on top of origin/mh/reflog-expire It can also be found at https://github.com/stefanbeller/git/tree/atomic-push-v12

Any comment is welcome!

Thanks, Stefan
