rust/src/test/rustdoc-ui/reference-links.rs, branch 1.52.1

Rename rustdoc lints to be a tool lint instead of built-in.

2021-03-02T00:29:15+00:00

- Rename `broken_intra_doc_links` to `rustdoc::broken_intra_doc_links` - Ensure that the old lint names still work and give deprecation errors - Register lints even when running doctests Otherwise, all `rustdoc::` lints would be ignored. - Register all existing lints as removed This unfortunately doesn't work with `register_renamed` because tool lints have not yet been registered when rustc is running. For similar reasons, `check_backwards_compat` doesn't work either. Call `register_removed` directly instead. - Fix fallout + Rustdoc lints for compiler/ + Rustdoc lints for library/ Note that this does *not* suggest `rustdoc::broken_intra_doc_links` for `rustdoc::intra_doc_link_resolution_failure`, since there was no time when the latter was valid.

Only report reference-style link errors once

This caused a diagnostic regression, originally it was: ``` warning: unresolved link to `std::process::Comman` --> link.rs:3:10 | 3 | //! [a]: std::process::Comman | ^^^^^^^^^^^^^^^^^^^^ no item named `Comman` in module `process` | = note: `#[warn(broken_intra_doc_links)]` on by default ``` but after that PR rustdoc now displays ``` warning: unresolved link to `std::process::Comman` --> link.rs:1:14 | 1 | //! Links to [a] [link][a] | ^^^ no item named `Comman` in module `process` | = note: `#[warn(broken_intra_doc_links)]` on by default ``` which IMO is much less clear.
