Options 

* modules/video_output/directx/directx.c: fixed the "refresh" button for the --directx-device option.
* modules/demux/dts.c: implemented DEMUX_GET_TIME and DEMUX_GET_LENGTH.
* modules/access/cdda.c: got rid of the cdda demux and add a wav header at the beginning of the data.
   This allows to correctly support DTS audio cd (demux will detect what kind of CD it is).
* modules/demux/wav.c: code cleanup and fixed seeking.
