v2.0-alpha1: DNS-over-HTTPS Support

Merge pull request #23 from cherrot/feature-dns-over-https

DNS-over-HTTPS (DoH) Support

v1.7: additional resolver format

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: udp+tcp@114.114.114.114,tcp@127.0.0.0:5353,1.1.1.1
• See README and help for details

v1.6

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.
