discovery: stop using nodemap for membership testing Nodemap is not aware of filtering so we need to ask the changelog itself if a node is known. This is probably a bit slower but such check does not dominated discovery time. This is necessary if we want to run discovery on filtered repo.

discovery: enforce filtering into revlogbaseddag._internalizeall One more step toward discovery running on filtered repo.

discovery: make revlogdag work on filtered repo The revlogdag class is a core part of discovery. We need its initialisation to exclude revision filtered out.

pull: run findcommon incoming on unfiltered repo The discovery is not yet ready for filtered repo. Pull was using filtered for its discovery which is wrong. It worked by dumb luck because discovery mainly use funtion that does not respect the filtering. Trying to makes discovery work on filtered repo revealed this bug.
