[PATCH 0/2] fetch: implement support for atomic reference updates

Hi,

this is a short patch series to implement support for atomic reference updates for git-fetch(1). It's similar to `git push --atomic`, only that it applies to the local side. That is the fetch will either succeed and update all remote references or it will fail and update none.
