This adds native support for the RTCDataChannel properties: https://developer.mozilla.org/en-US/docs/Web/API/RTCDataChannel/bufferedAmount https://developer.mozilla.org/en-US/docs/Web/API/RTCDataChannel/bufferedAmountLowThreshold And the RTCDataChannel event: https://developer.mozilla.org/en-US/docs/Web/API/RTCDataChannel/onbufferedamountlow The old callback, NotifyOutgoingMessageBufferEmpty, is deprecated as it didn't work very well. It will not be triggered and will be removed as soon as all users of it are gone. There is a new callback, OnTotalBufferedAmountLow, that serves the same purpose but also allows setting an arbitrary limit when it should be triggered (See DcSctpOptions::total_buffered_amount_low_threshold).
