Creates a new #GstCaps as a copy of the old @caps. The new caps will have a
refcount of 1, owned by the caller. The structures are copied as well.
Note that this function is the semantic equivalent of a gst_caps_ref()
followed by a gst_caps_make_writable(). If you only want to hold on to a
reference to the data, you should use gst_caps_ref().
When you are finished with the caps, call gst_caps_unref() on it.
