Subject: Support circular Requires loops

After the packages are parsed, pkg-config recurses through all the
required packages to generate one list. Before descending another level,
check to see if the package has already been handled and skip it. This
allows packages to require each other circularly by breaking the loop.

A test has been added resolving a two level deep circular dependency.
