ofono-{call,origin}: Send DTMF tones for active calls

Browse Source 
The oFono DTMF support doesn't match our model; you can only send
tones to the network and not to a particular call.  The telephony
standards dictate that only a single call can be active at a time so
we just get the call to emit a "tone" signal if the call is in the
active state and get the origin to listen for the signal.
