* fix: Synchronize peer logging with a channel We were depending on the close mutex to properly report connection state. This ensures the RTC connection is properly closed before returning. * Disable pion logging * Remove buffer * Try ICE servers * Remove flushed * Add diagram explaining handshake * Fix candidate accept ordering * Add debug logging to peerbroker * Fix send ordering * Lock adding ICE candidate * Add test for negotiating out of order * Reduce connection to a single negotiation channel * Improve test times by pre-installing Terraform * Lock remote session description being applied * Organize conn * Revert to multi-channel setup * Properly close ICE gatherer * Improve comments * Try removing buffered candidates * Buffer local and remote messages * Log dTLS transport state * Add pion logging
