Gochinadns Versions Save

Resolvers can now be passed in format: protocol[+protocol]@ip:port (where protocol is udp or tcp) This change is backwards compatible with ChinaDNS. If you use GoChinaDNS as a ChinaDNS drop-in you don't have to change anything if you don't want to use this feature.

• ip:port format still accepted, will default to udp+tcp@ip:port (same as before)
• Rightmost protocol is the (optional) fallback protocol
• Can mix and match formats
• Example: [email protected],[email protected]:5353,1.1.1.1
• See README and help for details

Many thanks to @beanslel 's work. Now we have a CI !?

Details:

• Update dependencies and update go to 1.15
• Remove default address for trusted-servers
• Update the latest version number in the binary file (print it with -V)
• Include mini binaries for embedded architectures (UPX compressed), can be useful for devices with limited storage such as routers.

Fix race conditions.

Fix nil pointer panic by copying dns message before mutate it.

Improve robustness

Do not panic when no resolvers available. Robustness goes first.
