            Use dlopen notes again

This requires updated dlopen-notes. A version dependency is introduced.

The levels of various dendencies were adjusted, see comments.

The motivation for this change is to make management of the dependencies
(Requires, Recommends, Suggests). Previously, we had to adjust the
depencencies whenever things were converted to dlopen, or the list
of libraries used was changed. This was tedious and hard to get right.
Now we have good metadata provided by upstream, so we mostly rely on
that only only do some overrides downstream.
