a=openpgp; fpr=57CE4C7F6375710FCB65C6063ED59F248E468C7F The reference backends obtain the committer information from `git_committer_info(0)` when adding a reflog. The upcoming patches introduce support for migrating reflogs between the reference backends. This requires an interface to creating reflogs, including custom committer information. Add a new field `committer_info` to the `ref_update` struct, which is then used by the reference backends. If there is no `committer_info` provided, the reference backends default to using `git_committer_info(0)`. The field itself cannot be set to `git_committer_info(0)` since the values are dynamic and must be obtained right when the reflog is being committed.
