repair: implement requirements checking for upgrades This commit introduces functionality for upgrading a repository in place. The first part that's implemented is testing for upgrade "compatibility." This is done by examining repository requirements. There are 5 functions returning sets of requirements that control upgrading. Why so many functions? Mainly to support extensions. Functions are easier to monkeypatch than module variables. Astute readers will see that we don't support "manifestv2" and "treemanifest" requirements in the upgrade mechanism. I don't have a great answer for why other than this is a complex set of patches and I don't want to deal with the complexity of these experimental features just yet. We can teach the upgrade mechanism about them later, once the basic upgrade mechanism is in place. This commit also introduces the "upgraderepo" function. This will be our main routine for performing an in-place upgrade. Currently, it just implements requirements checking. The structure of some code in this function may look a bit weird (e.g. the inline function that is only called once). But this will make sense after future commits.
