AudioDSP Extension Point Unit Tests

[AchimTuran]

Detailed Description

Within this issue unit tests will be written for AudioDSP V2.0.

Context

This issue will not directly be seen by end users of Kodi, but it will help to develop AudioDSP more quickly. Only the required parts will be used in tests and it is not required to run Kodi. Sure these test will only test the logic of AudioDSP and will not cover to deliver some real audio signals to the implementation.

Possible Implementation

So far I remember the Kodi project already used the Google Test framework, which I totally prefer to write my unit tests. Within this issue this question will be clarified.

Note: Team Kodi is considering this item, but we are not making any promises if and when it will be included.
