This is for https://github.com/mikedilger/resolv-rs/issues/11, where the end goal is to publish the 0.4 version of these crates.
The first step IMO is to publish the libresolv-sys crate. I've made some changes to make packaging work (and clean things up along the way):

Use the bindgen crate as a build dependency instead of requiring users to have the bindgen CLI installed. This makes the crate much easier to build and prevents lines like this in CI scripts: github.com/deshaw/srv-rs@ecf0a86560/.github/workflows/rust.yml (L36)
- Unignore lib.rs to make this work
Fix all the lints in build.rs
Specify an edition of 2021 (somewhat arbitrary) to prevent Cargo from defaulting to the ancient 2015 edition
Create a workspace and add libresolv-sys to it

Before (doesn't package):

> cargo package
   Packaging libresolv-sys v0.4.0 (/tmp/resolv-rs/libresolv-sys)
warning: ignoring library `libresolv_sys` as `lib.rs` is not included in the published package
error: failed to prepare local package for uploading

Caused by:
  no targets specified in the manifest
  either src/lib.rs, src/main.rs, a [lib] section, or [[bin]] section must be present

After (packaging works!):

> cargo package
   Packaging libresolv-sys v0.4.0 (/tmp/resolv-rs/libresolv-sys)
    Updating crates.io index
    Packaged 10 files, 15.3KiB (4.6KiB compressed)
   Verifying libresolv-sys v0.4.0 (/tmp/resolv-rs/libresolv-sys)
   Compiling clang-sys v1.8.1
   Compiling regex-automata v0.4.14
   Compiling libloading v0.8.9
   Compiling bindgen v0.72.1
   Compiling regex v1.12.3
   Compiling libresolv-sys v0.4.0 (/tmp/resolv-rs/target/package/libresolv-sys-0.4.0)
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 9.23s

If you want I can add you as another maintainer on crates.io. If so, let me know your handle there.
