Subject: debvm-create: move functionality into support files
The benefit of this change is that we don't have to escape that much. As
a consequence, it becomes easier to put more code into the customization
hooks, which have access to installed package versions. Thus we can
reduce the use of DEBVER and thus improve working with snapshot.d.o.
