[PATCH v4 0/7] ref-transaction-send-pack

Hi,

This series has been posted before[1], but is now rebased on the previous ref-transaction-rename.

It can also be found at github[2] and googlesource[3]

This series finishes the transaction work to provide atomic pushes. With this series we can now perform atomic pushes to a repository.

Version 2:
- Reordered the capabilities we send so that agent= remains the last
  capability listed.
- Reworded the paragraph for atomic push in git-send-pack.txt
- Dropped the patch for receive.preferatomicpush

Version 3:
- Fix a typo in a commit message.

Version 4:
* As Ronnie announced to change employers soon, he'll have only limited
  time to work on git in the near future. As this is a rather large patch
  series, he is handing this work over to me. That's why I'm sending the
  patches this time.

Thanks, Stefan
