 In order to get my new TracDarcs plugin working, I had to apply
 [http://artiemestieri.tn.it/~lele/projects/trac-darcs/trac-api-2866.patch
 this patch] that

  1. Fixes #2731
  1. Adds an "hash" field to the `revision` table
  1. Moves the actual insertion of the cache data from the
 `CachedRepository` class to the `Changeset` one

 Point 3 allows the backend to augment the cached data as needed, simply by
 overriding a `Changeset` method (see
 [http://artiemestieri.tn.it/~lele/projects/trac-
 darcs/tracdarcs/changeset.py for example]).

 Of course, I could have reimplemented the whole `sync()` machinery in a
 subclass of `CachedRepository`, but DRY approach suggests that's not the
 right way.
