Fix negotiation.
* gst/adder/gstadder.c: (gst_adder_link), (gst_adder_init),
(gst_adder_request_new_pad): Fix negotiation.
* gst/goom/gstgoom.c: (gst_goom_init), (gst_goom_src_fixate):
Add a fixate function.

Completely rewrite the negotiation.  Doesn't quite work yet,
due to some buffer-frames problem.
