This PR stabilizes the `#[diagnostic]` attribute namespace and a minimal
option of the `#[diagnostic::on_unimplemented]` attribute.
The `#[diagnostic]` attribute namespace is meant to provide a home for
attribute that allow users to influence error messages emitted by the
compiler. The compiler is not guaranteed to use any of this hints,
however it should accept any (non-)existing attribute in this namespace
and potentially emit lint-warnings for unused attributes and options.
This is meant to allow discarding certain attributes/options in the
future to allow fundamental changes to the compiler without the need to
keep then non-meaningful options working.
The `#[diagnostic::on_unimplemented]` attribute is allowed to appear
on a trait definition. This allows crate authors to hint the compiler
to emit a specific error message if a certain trait is not implemented.
For the `#[diagnostic::on_unimplemented]` attribute the following
options are implemented:
* `message` which provides the text for the top level error message
* `label` which provides the text for the label shown inline in the
broken code in the error message
* `note` which provides additional notes.
The `note` option can appear several times, which results in several
note messages being emitted. If any of the other options appears several
times the first occurrence of the relevant option specifies the actually
used value. Any other occurrence generates an lint warning. For any
other non-existing option a lint-warning is generated.
All three options accept a text as argument. This text is allowed to
contain format parameters referring to generic argument or `Self` by
name via the `{Self}` or `{NameOfGenericArgument}` syntax. For any
non-existing argument a lint warning is generated.

Since around GitoxideLabs/gitoxide#1536, fuzzing is broken for `gitoxide` due to an error related to `serde`. As shown there and in GitoxideLabs/gitoxide#1596, the error is: error[E0658]: `#[diagnostic]` attribute name space is experimental --> /rust/registry/src/index.crates.io-6f17d22bba15001f/serde-1.0.210/src/de/mod.rs:536:5 | 536 | diagnostic::on_unimplemented( | ^^^^^^^^^^ | = note: see issue #111996 <rust-lang/rust#111996> for more information = help: add `#![feature(diagnostic_namespace)]` to the crate attributes to enable = note: this compiler was built on 2024-02-11; consider upgrading it if it is out of date Since rust-lang/rust#111996 is closed as completed, and similar errors appear to have been fixed in oss-fuzz for other projects by using the latest nightly toolchain, this makes the same change for `gitoxide` as was made in - google#12404 for `starlark-rust` - google#12409 for `rhai` See also google#12410.
