Finish Adding Functional Tests

[bashwork]

Finish adding the functional tests for all the server code and finish the unit test for the remainder of the server/client code.

Make sure that we are also using correct reference implementations (jamod, modpoll, etc) for each test:

• sync/async server
• sync/async client
• special contexts

Closing this for now.

We have to rework the whole test scenario, since it has grown a bit chaotic to say the least.
