Adding NetAudio sample server with simple connection to a sample generator class and example code in NetAudioTest

Updating some more interfaces and retrating default options where interface is not used by external user

Refactoring. And fixing problem with ring buffer size in NetAudioStream initialization. Was giving an overhead of 3x the capacity ...

Client wartet nicht mehr, beide senden einfach => running, aber nicht optimal.latenz kann noch durch verbesserung verringert werden, da die warte zeit von 1mszu lang ist,

Client-initialized close is accepted by server and client waits for acknowledge before closing connection

Fixing little bug in channel patching of net audio test (modulo was used in a wrong way to create alternating indices)

implemented parameter setting for server when connection a data source
switching to vista output stream (works with concurrent writes from different threads)
