[PATCH v21 00/19] Use ref transactions

[Ronnie Sahlberg <sahlberg@google.com>]

List, Jun

Here is a resend of the first part of the ref transactions patches.
This new series consists of the first 19 patches in the series and
have been reviewed by mhagger.
This series should be good to go now.

I will resend the remaining part of the series separately once I have addressed
Michaels concerns.


Version 21:
 -- split the patch series in two. These are the first 19 patches that
    are now reviewed by mhagger.

  refs.c: add a strbuf argument to ref_transaction_commit for error
