clfilter: add a cache on repo for set of revision to filter for a given set.
Recomputing the filtered revisions at every access to changelog is far too
expensive. This changeset introduce a cache for this information. This cache is
hold by the repository (unfiltered repository) and invalidated when necessary.
This cache is not a protected attribute (leading _) because some logic that
invalidate it is not held by the local repo itself.
