dpkg let packages disappear then they have no files any longer and
nothing depends on them. We need to collect this as dpkg as well as
APT doesn't know beforehand that the package will disappear, so the
only possible option is to tell the user afterwards about it.
To enhance the experience we also try to forward the auto-install
flag so the disappear-causer(s) are not autoremoved next time -
for the transfer to happen the disappeared version needs to depend
on the package the flag should be forwarded to and this package
needs to declare a Replaces on the disappeared package.
