Bug fixes

- Fix support of 'inheritances' configuration parameter: only no-parent spec ("A:") was respected; Extend TestInheritance unit test;
- Change in test make and cmake files for older Julia releases (<1.9) that do not provide the pkgversion() function.
- Fix a bug in test/make.rules affecting set of CxxWrap release.
