RTCDataChannel.senddocuments that it throws when the message cannot be queued, but the nativeSendresult was ignored, so a message sent before the channel opened or after it closed was silently dropped. libwebrtc returns false in exactly those cases, and when the send queue overflows. The result is now checked and a rejected send throws, which makes the documented behavior real. Callers that send during teardown and relied on the silent drop will now see the exception.
