Implements an alternative to PortAudio on Windows which uses Windows Audio Session API (WASAPI) and related Core Audio APIs such as Multimedia Device (MMDevice) API.

Commits the C source code of a refining of the automatic audio device selection to pick up devices from the same hardware.

Modifies automatic audio device selection to attempt to pick up capture and playback/notify from the same hardware. Fixes warnings. Adds javadocs.

- Removes the DirectSound support from PortAudio in order to prevent issues with bad audio quality.
- Attempts to recognize USB PortAudio devices on Windows as such, ignores the virtual Microsoft Sound Mapper devices to avoid user confusion. Contributed by Vincent Lucas.

Improves device selection via portaudio for MacOSX (hostapi coreaudio): adds the possibility to get the device transport type (USB, bluetooth, etc.) and an unique identifier. Corrects problems when: loading the same device twice (for the moment only for the same hostapi), a new plugged device is selected during a call or if the selected device is unchanged.

Improves sound device selection: automatically switches to new plugged device, remember user preferences in a list.
