PSA: Extra validation for TURN and STUN URLs in Chromium M110

[gui...@webrtc.org]

Starting on milestone 110, Chromium will perform stricter validation of TURN and STUN URLs passed to the constructor of an RTCPeerConnection. More specifically, STUN URLs will not support a query section, and TURN URLs will support only a transport parameter in their query section.

This aligns Chromium with the corresponding specifications[1,2]

The following are examples of URLs that were accepted before that will no longer be valid:

• turn:example.org?x=y
• stun:example.org?transport=udp

Best regards,
GU
