Explicit facilities in bzrlib for different-model repositories.

Registered by Robert Collins on 2006-08-21

As we upgrade bzr's data model we need to keep interoperating with old format repositories, and for somethings like testaments and bundles we need an exact representation of the objects for that model. We should add a small, constrained facility to bzrlib to allow getting an old model of a Revision and RevisionTree, but have the entire codebase be built around the latest data model. This reduces the opportunity for serious bugs, because rather than having conditional code in multiple places, only points-of-conversion will need to know there have ever been multiple models.
