osmux: add option to pad the circuit with dummy messages
Iridium is a satellite network which operates a GPRS-like that allows you to get speeds up to 128kbit/s. However, it takes from 5 to 6 secs to get the bandwidth allocated, so the conversation is garbled during the time. This patch uses the new dummy padding support in libosmo-netif that is controlled through the osmux osmux_xfrm_input_open_circuit(). This includes a new VTY option for osmux.
