osmux: introduce osmux_xfrm_input_open_circuit()
This new function allows you to create a circuit on an existing input handle.
We don't create the circuit anymore from the first packet seen, instead the
client application is in full control of opening and closing the circuit.
This change includes a new feature to pad a circuit until we see the first
packet that contains voice data. This is useful to preallocate bandwidth on
satellite links such as Iridium/OpenPort.
