Original commit message from CVS: * gst/elements/gsttee.c: (gst_tee_init), (gst_tee_request_new_pad): Remove usage of gst_pad_proxy_fixate. * gst/gstcaps.c: (gst_caps_append), (gst_caps_append_structure), (gst_caps_split_one), (gst_caps_replace): Add poisoning code. * gst/gstmarshal.list: Add pointer__pointer for fixate signal * gst/gstpad.c: (gst_real_pad_class_init), (_gst_real_pad_fixate_accumulator), (gst_pad_link_fixate), (_gst_pad_default_fixate_func), (gst_pad_proxy_fixate), (gst_pad_set_explicit_caps), (gst_pad_template_new): Add poisoning code. Add fixate signal on RealPad. Change set_explicit_caps() to take const GstCaps, like try_set_caps(). * gst/gstpad.h: * testsuite/caps/Makefile.am: * testsuite/caps/app_fixate.c: Add a test for the fixate signal
