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.
