[Development] abandoning stale changes on gerrit

[Oswald Buddenhagen]

moin *,

5.0 is out and the 5.1 feature freeze isn't that far off any more.
seems like the best time for some serious house cleaning.
therefore i'd like to urge everyone to give their pending changes which
haven't seen activity for a long time a honest look.
please explicitly mark the ones you still want to work on by adding a
comment. everything which has no indication of (planned) activity in a
few weeks will be abandoned by administrative action.
if you are an ex-troll/-nokian, please also check the dashboard of your
alter ego.
if you are a maintainer, give identified drive-by contributors a ping.
i'd also like to encourage everyone to adopt orphaned changes they have
an interest in.

regards
