transaction: make entries a private attribute (API)...

transaction: make entries a private attribute (API) This attribute is tracking changes to append-only files. It is an implementation detail and should not be exposed as part of the public interface. But code in repair was accessing it, so it seemingly does belong as part of the public API. But that code in repair is making assumptions about how storage works and is grossly wrong when alternate storage backends are in play. We'll need some kind of "strip" API at the storage layer that knows how to handle things in a storage-agnostic manner. I don't think accessing a private attribute on the transaction is any worse than what this code is already doing. So I'm fine with violating the abstraction for transactions. And with this change, all per-instance attributes on transaction have been made private except for "changes" and "hookargs." Both are used by multiple consumers and look like they need to be part of the public interface. .. api:: Various attributes of ``transaction.transaction`` are now ``_`` prefixed to indicate they shouldn't be used by external consumers.
