This adds a new script tools/check-version-history.py and a corresponding test when building in developer mode. It checks manpages (except dbus documentation which is handled by update-dbus-docs) for missing version history information. It also adds ignore lists based on version 183 (the version that our version annotations go back to). These can be augmented if we want to ignore other elements if it doesn't make sense for them to have version annotations.
