Use waf port group

[raimue (Rainer Müller)]

The waf port group​ is meant to simplify port using the waf build system.

I searched for existing ports and converted these to the new port group. I am attaching a patch for each port to this ticket. Please test these patches and if it works, commit them.

Unfortunately, some of these ports or its dependencies were already broken for me before making my changes, which is why I am not committing them right away even if the port is openmaintainer.
