discovery: add extinct changesets to outgoing.excluded...

discovery: add extinct changesets to outgoing.excluded Before this change, push would incorrectly fast-path the bundle generation when extinct changesets are involved, because they are not added to outgoing.excluded. The reason to do so are related to outgoing.excluded being assumed to contain only secret changesets by scmutil.nochangesfound(), when displaying warnings like: changes found (ignored 9 secret changesets) Still, outgoing.excluded seems like a good API to report the extinct changesets instead of dedicated code and nothing in the docstring indicates it to be bound to secret changesets. This patch adds extinct changesets to outgoing.excluded and fixes scmutil.nochangesfound() to filter the excluded node list. Original version and test by Pierre-Yves.David@ens-lyon.org
