Original commit message from CVS: * sys/directsound/gstdirectsoundsink.h: * sys/directsound/gstdirectsoundsink.c: Add an attenuation property that will directly attenuate the directsound buffer. Change the size of the directsound secondary buffer to a half second. Add more debug logs. Add a lock to protect dsound buffer write access. Fix a bad implementation of reset. * sys/directsound/gstdirectdrawsink.c: * sys/directsound/gstdirectdrawsink.h: Add a keep_aspect_ratio property. Do not use overlay if not supported. Add more debug logs. Remove overwrite of WM_ERASEBKGND message handling. It was not redrawing border when keep_aspect_ratio was enabled. * win32/common/config.h: update version waiting an auto-generated config.h
