Re: [sr-dev] [kamailio/kamailio] rfc5952#section-4.3 conformance: IPv6 address in lower case (#2488)

I have tested this update. The current `Kamailio` behavior as expected. ``` INVITE sip:+19163120077@example.com SIP/2.0 Record-Route: sip:[2600:1f18:40ed:da06:ae55:4e63:67e5:e60a];transport=tcp;r2=on;lr=on;ftag=daFBsTkhF Record-Route: sip:3.236.25.4;transport=tcp;r2=on;lr=on;ftag=daFBsTkhF Via: SIP/2.0/TCP [2600:1f18:40ed:da06:ae55:4e63:67e5:e60a];branch=z9hG4bK155b.223c92df834dbcc962418d2f49797a80.0;i=89 Via: SIP/2.0/TCP 192.168.2.10:41322;received=91.224.133.8;branch=z9hG4bK.YxTlXA4AD;rport=41322 From: "test" sip:6157778900@example.com;tag=daFBsTkhF To: sip:+19163120077@example.com ```

As I understand not chance to backport to `5.4`, `5.3` and `5.2` branches.
