[PATCH 00/15] ref-transactions-reflog

[Ronnie Sahlberg]

List,

Please find a patch that updates the reflog handling to use transactions.
This patch series has previously been sent to the list but is now rebased on
the current content of next which contains ref changes we depend on in this
series.

This series converts the reflog handling and builtin/reflog.c to use
a transaction for both the ref as well as the reflog updates.
As a side effect of this it simplifies the reflog marshalling code so that we
only have one place where we marshall the entry.
It also means that we can remove several functions from the public api
towards the end of the series since we no longer need those functions.

This series can also be found at
