Corrects deadloack between the CoreAudio AudioDeviceStop function and the stream processing callback.

Adds stream capture and render via CoreAudio for MacOSX. This is a first version which needs more testing. The default audio system on MacOSX is still PortAudio.

Addresses issues with hotplugging and playback device selections during calls in the Windows Audio Session API (WASAPI) integration when acoustic echo cancellation (AEC) is enabled.

Handles hotplugging and playback device selections during calls in the Windows Audio Session API (WASAPI) integration when acoustic echo cancellation (AEC) is enabled.

Implements acoustic echo cancellation (AEC) in the integration of Windows Audio Session API (WASAPI) using the Voice Capture DSP in source (as opposed to filter) mode.

Fixes issues with the Renderer implementation using Windows Audio Session API (WASAPI) related to the playback and/or notify device selections being set to 'none'.

Allows opening the CaptureDevice implementation using Windows Audio Session API (WASAPI) when the playback device selection is set to 'none'.

Allows disabling the playback mid-stream when running Windows Audio Session API (WASAPI) without acoustic echo cancellation.

Fixes an issue in the Windows Audio Session API (WASAPI) integration which could cause the audio capture to fail on certain devices if acoustic echo cancellation is enabled.

Fixes a problem with the Renderer implementation of Windows Audio Session API (WASAPI) which could cause loss of playback after switching the playback device during a call.

Adds volume to RFC4733 dtmf packets and handling of an account property to change default value. Changes the default minimum tone duration.

Commits the fix of a bug in the acoustic echo cancellation (AEC) of Windows Audio Session API (WASAPI).on behalf of Charles Stedman.

Attempts to optimize and improve the acoustic echo cancellation (AEC) with Windows Audio Session API (WASAPI).

Enables libjitsi to programmatically override the default settings on various properties of the Voice Capture DSP that implements acoustic echo cancellation (AEC) on Windows.

Fixes (i.e. implements a workaroundfor) an issue which would cause the acoustic echo cancellation (AEC) voice capture DMO to go into endlessly calling IMediaBuffer::SetLength.

Commits work in progress on implementing acoustic echo cancellation (AEC) on Windows using Voice Capture DSP.
