I enabled trust-dns feature on musl builds because its resolver does not support TCP and might also miss other features since it is quite compact.

I've started a release build for this PR https://github.com/cargo-bins/cargo-binstall/actions/runs/2917842935 to see how it affects binary size.

If it's okay size wise we should just enable it by default, proper DNS resolution is the right thing to do, especially given the various issues with getaddrinfo

I've run the CI on both main and this PR.

The result is roughly 0.5M increase.

P.S. it seems that the past PRs have caused the bin size to increase by 1-2M, might be worth investigation.

Given that trust-dns only increase the binary size by 0.5M, I've enabled it by default.
Now we should have dnssec support using ring and dns over tls support for all targets.

Though trust-dns only supports dns over https if rustls is used, thus the binaries built for windows does not have
dns over https since the CI enables native tls feature for windows.

In the future, trust-dns will also support dns over quic (http3), which also only supports rustls.

@passcod Shall we enable rustls feature on windows?

I think so yes, that will also allow us to have consistent secure transport rules e.g. wintls not supporting 1.3 on some windows versions

Done!

Note that this is before compression.

I was comparing size before compression vs size after compression.

Hmm well, I think it's worth it for the feature set it adds.
