Test freedesktop-sdk 1.8 to ensure stability and maintain ABI
Milestone ID: 509260
We now have a runtime that can be used to run apps that rely on the old freedesktop 1.6 SDK. However this has only been confirmed from a small set of test cases, provided by individual users along the way.
This milestone will try to provide a clear way to track what tasks are needed to ensure we are providing a solid test environment and also track what measure we put in place to monitor ABI stability.
