I ended up with the gentle chainsaw approach on this, no comparison code
means nothing to convert.
The comparisons on header and dependency set objects are awfully ambiguous
(and the mapping is plain weird in case of rpm.ds), I figured its better
just rip it. For header version comparisons there's rpm.versionCompare()
which has clear enough semantics, and provides a way to write compatible
code. For rpm.ds there's no compatible way, but AFAIK nobody is actually
using the comparisons. If somebody does, we'll hear sooner or later...
