[PATCHv7 0/9] atomic pushes

The patch 
        [PATCH 4/7] receive-pack.c: receive-pack.c: use a single ref_transaction for atomic pushes
was dropped and redone as 3 separate patches. This wasn't just done for doing it,
but the end result has also changed. We have more smaller functions doing
one thing instead of these larger functions. Thanks for the ideas, Eric!

Also the advertisement of the atomic capabilites was moved to a later new patch in this series. This helps when you want to bisect this series later. Thanks Michael for pointing this out!

Thanks, Stefan
