Creates a new Caps as a copy of the old this.
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.
