The original code was non-working because the notication was never
setup correctly and resulted in a DSERR_INVALIDCALL. A proper fix
would look like:

         if( sys->p_notify )
         {
+            IDirectSoundBuffer_Stop( aout->sys->p_dsbuffer );
             DSBPOSITIONNOTIFY notif = {.dwOffset = aout->sys->i_write, .hEventNotify = sys->hnotify_evt } ;
             if( IDirectSoundNotify_SetNotificationPositions( sys->p_notify, 1, &notif ) ==  DS_OK )
             {
+                IDirectSoundBuffer_Play( aout->sys->p_dsbuffer, 0, 0, DSBPLAY_LOOPING );
                 WaitForSingleObject( sys->hnotify_evt, INFINITE );
                 IDirectSoundBuffer_Stop( aout->sys->p_dsbuffer );
             }

But fixing it makes the problem worse since the notification is setup
too late and thus the buffer will replay a full loop of the back
buffer during a drain.

With the reference counting stuff, the AVFrame structure is gone or
unreachable by the time the release function is called.

This will simplify later commits.

This can happen in some corner cases such as flushing (luckily the leak
would automatically be resolved when the device instance is released).

This reenables direct rendering with libavcodec in most cases.

Functions are provided to:

 * query the available equalizer presets
 * create a new default equalizer instance
 * create an equalizer instance from a preset
 * set individual equalizer band amplitudes
 * set equalizer pre-amplification
 * apply an equalizer to a media player

Equalizer settings can be applied whether media is playing or not,
and will automatically be retained when playing media subsequently.
