Second round of the new Windows ADM is now ready for review. Main changes are: Supports internal (automatic) restart of audio streams when an active audio stream disconnects (happens when a device is removed). Adds support for IAudioClient3 and IAudioClient2 for platforms which supports it (>Win8 and >Win10). Modifies the threading model to support restart "from the inside" on the native audio thread. Adds two new test methods for the ADM to emulate restart events or stream-switch events. Adds two new test methods to support rate conversion to ensure that audio can be tested in loopback even if devices runs at different sample rates. Added initial components for low-latency support. Verified that it works but disabled it with a flag for now.
