Preserve value of send_silence_when_idle if possible In commit 55d01d3defed4bfdc74704dbea0da9548a97a979 we set send_silence_when_idle to -1 rather than 400 when SRTP is engaged. But this left no way to enable white noise silence when desired. When SRTP is engaged we can't simply not send RTP because it breaks too many devices. So we need to prevent send_silence_when_idle from being unset or being set to zero. This change allows it to be set to other values so as to feed white noise rather than all zeros into the codec.
