This series conflicts with the first part of Max' "BlockBackend and
media" series which I already merged to my tree. I tried to resolve the
conflict while applying, but while it doesn't seem really hard to do,
it's a bit more involved than what I'm willing to do while applying.
So I'm afraid I have to request another rebase.
