Added threads functions to APRSDPluginBase

Browse Source 
This patch updates the APRSDPluginBase class to include
standard methods for allowing plugins to create, start, stop
threads that the plugin might need/use.  Also update the aprsd-dev
to correctly start the threads and stop them for testing plugin
functionality.
Also added more unit tests and fake objects for unit tests.
