Extracted from expire_reflog_ent() a function that is solely
responsible for deciding whether a reflog entry should be expired. By
separating this "business logic" from the mechanics of actually
expiring entries, we are working towards the goal of encapsulating
reflog expiry within the refs API, with policy decided by a callback
function passed to it by its caller.
