gst_pad_get_internal_links() is not thread safe. If pads are removed from a
running element (like a tee), it can cause a crash when it tries to push an
event onto a no-longer-existing pad.

I propose adding a gst_pad_iterate_internal_links() that returns a GstIterator*
and is thread-safe.

I'm attaching a sample implementation.
