Calls gst_pad_get_allowed_caps() for every other pad belonging to the
same element as pad, and returns the intersection of the results.
This function is useful as a default getcaps function for an element
that can handle any stream format, but requires all its pads to have
the same caps. Two such elements are tee and aggregator.
