StunServer is updated to ensure registring for receiving packet from the socket is happening on the same thread as where the packets are recevied. Bug: webrtc:15368, webrtc:11943 Change-Id: I94cc3a47278d5489de7f170c8d43015d1551c437 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/328120 Commit-Queue: Per Kjellander <perkj@webrtc.org> Reviewed-by: Jonas Oreland <jonaso@webrtc.org> Reviewed-by: Harald Alvestrand <hta@webrtc.org> Cr-Commit-Position: refs/heads/main@{#41219}
