Original commit message from CVS: * ext/faac/gstfaac.c: (gst_faac_class_init), (gst_faac_init), (gst_faac_sink_setcaps), (gst_faac_src_setcaps), (gst_faac_sink_event), (gst_faac_chain), (gst_faac_set_property), (gst_faac_get_property), (gst_faac_change_state): Gst09-ize code a little bit more: use gst_pad_alloc_buffer(), move event handling from chain function into an event function, add some locks here and there, do some cleanups; disable 32-bit integer and float input formats until we're sure that those actually work (couldn't play back the produced files with anything).
