• Merge v2ray-core 5.20.0 changes.
• Fix some issues about IP certificate and SNI.
• Fix DNS over HTTPS "V is not in context" panic.
• Support dialing TLS with ECH config on client side. Please note that the traffic of HTTPS queries does not go through the routing component. Currently Go does not support ECH on server side, so a server supporting the TLS stack of CloudFlare's Go fork (e.g. sing-box) or a server written in other languages is needed.
• Remove the asynctimerchan=1 workaround. Go 1.23.2 should have fixed the timer bug that causes quic-go and other libraries broken.
• Let h2 (a.k.a. http) transport also support HTTP3.
• Experimentally support splithttp browser dialer.
