This function will call installed block probes before triggering any
installed data probes.
The function proceeds calling the chain function on the peer pad and returns
the value from that function. If pad has no peer, #GST_FLOW_NOT_LINKED will
be returned. If the peer pad does not have any installed chainlist function
every group buffer of the list will be merged into a normal #GstBuffer and
chained via gst.pad.Pad.chain.
In all cases, success or failure, the caller loses its reference to list
after calling this function.
Pushes a buffer list to the peer of pad.
