* ./modules/gui/macosx/aout.m: cleaned up the code, removed intf dep. 

  * ./src/misc/darwin_specific.m: fixed segfault (o_enumerator was being
                                  released twice) and memory leak.

    Bonne Ann�e!

* MacOSXSoundOption
* Each audio device can give several sound options: there might be several

* as an option.
* We record format and channels, since these attributes are requirements
* from the user and the aout should deliver what the user wants. This
* selection is basically done when the user chooses the output option.
* We do not record sample rate and bit depth, since these attributes are
* tied to the media source, and the device format that matches these media
* formats best should be selected. This selection is done when the aout
* module is created with a certain stream, and asks the asystm for a device.
