clfilter: make localpeer use a repo with "unserved" filter

This changeset installs a broad filter on most repos used for
serving. This removes the need to use the `visiblehead`/`visiblebranchmap`
functions, and ensures that changesets we should not serve are in
fact never served.

We do not use filtering on hgweb yet, as there is still a number
of issues to solve there.
