[PATCH 0/5] use packed refs for ref-transactions

This is a small patch series that continues ontop of the ref-transactions-rename series I posted earlier today.

This series expands the use of the packed refs file to make multi-ref updates much more atomic. Additionally it allows us to continue pushing external caller to use transactions instead of accessing (packed) refs directly which allows us to remove a whole bunch of refs functions from the public api.

After this series there is no real need any more to expose that packed refs even exist to external callers.

This series is built ontop of the previous series that was posted earlier
today as :

  refs.c: move reflog updates into its own function

    one ref

  refs.c: make repack_without_refs static
  refs.c: make the *_packed_refs functions static
