A patch implementing the requested feature

Even though the caps GST_VIDEO_CAPS_RGB_16 and GST_VIDEO_CAPS_RGB_15 are
defined in gst-libs/gst/video/video.h, there is incomplete support for these
formats.

For instance, calling gst_video_format_parse_caps with one of these caps will
fail.

I suggest adding better support for these formats.  I include a patch that
implements this support.

It basically imply:
- adding 4 new video formats to the GstVideoFormat enum, which are
GST_VIDEO_FORMAT_{RGB,BGR}{15,16}
- adding 2 new caps, which are GST_VIDEO_CAPS_BGR_{15,16}
- adding the supporting code in gst-libs/gst/video/video.c in the different
gst_video_format_* functions
