This patch series is available also from
https://github.com/rsahlberg/git/tree/ref-transactions-next
and is based on
https://github.com/rsahlberg/git/tree/ref-transactions
This is a preview of the direction for the transaction work and finished
converting also reflog handling to transactions. This greatly simplifies
both the implementation of rename_ref in refs.c as well as reflog.c
This patch series is not fully finished and can not be applied until
the previous series is merged. Once this series is finished we will be
in pretty good shape to start experimenting with alternative refs backends
such as a TDB database.
