Luckily, Cargo doesn't mind circular dev-dependencies and we can patch
to ensure it's using the same version. We can also leave this as a
`git = "..."` dependency if we want, since it's a dev dependency.
- Added the `bindgen-ctru-sys` to be able to use `ParseCallbacks` when generating the bindings.
- Updated `doxygen-rs` to 0.4, which has a faster engine and more extensible internal (even though there are some regressions).
- Removes the `docstring-to-rustdoc` package because it is no longer needed.
All of our 3DS changes have been upstreamed. If in the future we need
to use the fork again, we can edit the top-level Cargo.toml and adjust
the patches (replace upstream with fork).
We don't want duplicate ctru-sys crates in the dependency graph. Same
for libc. We can patch them here to avoid any issues.
Now that we don't have duplicate ctru-sys crates, we can add back the
links field. This field is important because it warns us when there are
two crates linking to the same library (ex. duplicate ctru-sys crates).
