addressing universe/multiverse merges in +1 maintenance

[Matthias Klose]

With the feature and Debian import freeze approaching in about three weeks, I'd
like to propose to also address universe/multiverse merges in our +1 maintenance
tasks within these three weeks.  There's a lot untouched for more than one or
two years.

For merges of the main pocket, owned by the Foundations team, we had some time
addressed after a regular meeting to evaluate those merges, starting with the
oldest (and maybe scariest ones) first. Outcome of these were either removal
requests, or merges.  We have up to three +1 maintainers per day, so such an
evaluation could be done within a group as well.

Please make sure that a merge still builds (maybe keep a browser tab open), and
bonus points for a successful migration to the release pocket ;)
