Use the ICMP error response facility
Add code in IPv6 to send ICMP packets while processing extension headers. Add some accounting in processing IPV6 Extension headers which allows us to report meaningful information back in ICMP parameter problem packets. IPv4 also needs to send a message when an unsupported protocol is requested. Add some tests to generate both ipv4 and ipv6 packets with various errors and check the responses. Add some new checkers and cleanup some inconsistencies in the messages in that file. Add new error types for the ICMPv4/6 generators. Fix a bug in the ICMPv4 generator that stopped it from generating "Unknown protocol" messages. Updates #2211 PiperOrigin-RevId: 334661716
