The function returns #GST_FLOW_FLUSHING if the pad was flushing.
If @pad was not negotiated properly with a CAPS event, this function
returns #GST_FLOW_NOT_NEGOTIATED.
The function proceeds calling the chainlist function installed on @pad (see
gst_pad_set_chain_list_function()) and the return value of that function is
returned to the caller. #GST_FLOW_NOT_SUPPORTED is returned if @pad has no
chainlist function.
In all cases, success or failure, the caller loses its reference to @list
after calling this function.
Chain a bufferlist to @pad.
