Adding specification of more protocols

[ben221199]

This pull request adds specifications of more protocols than only dnsaddr.

I think this pull request should be merged when I have added more, but now it is already possible to see the changes and talk about improvements.

Very much appreciated! Thanks for the help here!

To prevent any of the discussions on one protocol to block merging another, I would suggest to use separate pull requests for each. That is not a strong opinion though.

I think that adding the basis using this pull request is fine. We can add more information for a specific protocol using other pull requests.

@mxinden Also, can you tell me what the binary format of dns, dns4, dns6 and dnsaddr is? Is it already defined? If not, I would suggest the FQDN format with a length-byte for every label.

Also, I have made some other pull requests on this and on other repositories. Hope someone can take a look at those too.

Hope I understand your question correctly @ben221199. As far as I know it is just the utf-8 byte representation.

w.write_all(encode::usize(bytes.len(), &mut encode::usize_buffer()))?;

This code above will prefix the data with an unsigned byte, yes.

Are the implementations in this organization authoritive at the moment, or is it still possible to alter the binary format at this time?

[ben221199]

Okay, I think I added enough protocols for now. I think that, except for maybe some slight changes, this pull request can be merged.

They are used in many production systems, thus I would say yes.

Above suggestions are applied.
