rebase: ensure rebase does not revive extinct revision

Here, we exclude hidden changesets from a rebase operation. If we
don't, a rewritten version of the hidden changesets will be created
by rebase. Those rewritten versions won't be hidden and will likely
conflict with other rewriting or revive pruned changeset. Moreover,
rewriting hidden revisions will surprise the user.

This change would not be necessary if changelog filtering were
already in core. But it's fairly cheap and helps to increase the
test-suite for such filtering.

Once changelog level filtering is added, hidden changes will be
automatically excluded or included according to the global --hidden
flags. Plain ignoring them is good enough for now.
