[PATCH] winegstreamer: Fix YUV->RGB conversion by copying colorimetry information.

[Akihiro Sagawa]

This patch adds a new GStreamer element called yuvfixup, which copies
colorimetry information from its super upstream source to its sink.
By using yuvfixup element, the colorimetry informaiton match on
videoconvert's sink pad and its source pad. Thus, we can avoid
expensive YUV matrix conversions and do YUV->RGB conversion with matrix.
