[PATCHv6 0/7] atomic pushes

[Stefan Beller <sbeller@google.com>]

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 github[1].

This series incorporates all suggestions by Eric. Most changes appear in
patch 4/7 as it is a complete rewrite compared to v5 of this patch series.
5/7 is new to the series and cleans up the rewrite by moving the function
execute_command around.

Any comments are welcome!

Thanks,
Stefan
