[Rpm-maint] [rpm-software-management/rpm] Version range dependency (#159)

[Florian Festi]

Further examination yields that libsolv already supports a way of dealing with this: REL_WITH which is represented in libsolvs dependency language as "+" and we probably want to represent in RPM as "with".

The semantic of the with operator is both sides need to be matched by the same package. For ease of  implementation nesting of "and" terms is not supported (as they would yield tuples of packages as solution). "or" clauses are suppoerted, though. "if" and "if" "else" clauses should be supported but this needs further investigation.

I have POC patch extending the rich deps parser in RPM to allow "with" and to check and reject "and" nested in "with" clauses. The - more complicated - part of actually checking if there is a single package matching is still missing though. In the patch "with" is treated like "and".
