octave: libinterp/dldfcn/audiodevinfo.cc annotate

annotate libinterp/dldfcn/audiodevinfo.cc @ 19547:c5b8a91baec6

avoid unnecessary use of pointer in audio code * audiodevinfo.cc (audioplayer::get_left): Return RowVector instead of pointer to RowVector. Method is now const. Change all uses. (audioplayer::get_right): Likewise. Handle case of single channel audio here. (portaudio_play_callback): Not here.
