Update release documentation
When updating the beta branch, we want to reset, instead of rebase. Otherwise we might produce again new commits on the beta branch, that aren't on the master branch.

Rename tables to typecheck_result()
While working on #6130, I noticed that part of the documentation was updated to use `LateContext::typeck_results`, but the paragraph still referred to the old `tables` field of `LateContext`.

Clippy dev subcommand to build and serve website
This PR adds `clippy dev serve` which will pop open a browser with a local rendered 'ALL the Clippy Lints' website, and re-render as you edit stuff.

clippy_lints: Do not warn against Box parameter in C FFI
changelog: [`boxed_local`]: don't lint in `extern fn` arguments
Fixes#5542.
When using C FFI, to handle pointers in parameters it is needed to
declare them as `Box` in its Rust-side signature. However, the current
linter warns against the usage of Box stating that "local variable
doesn't need to be boxed here".
This commit fixes it by ignoring functions whose Abi is C.
Downgrade string_lit_as_bytes to nursery
Between #1402 (regarding `to_owned`) and #4494 (regarding `impl Read`), as well as other confusion I've seen hit in my work codebase involving string_lit_as_bytes (`"...".as_bytes().into()`), I don't think this lint is at a quality to be enabled by default.
I would consider re-enabling this lint after it is updated to understand when the surrounding type information is sufficient to unsize `b"..."` to &\[u8\] without causing a type error.
As currently implemented, this lint is pushing people to write `&b"_"[..]` which is not an improvement over `"_".as_bytes()` as far as I am concerned.

changelog: Remove string_lit_as_bytes from default set of enabled lints
RunCompiler::new takes non-optional params, and optional
params can be set using set_*field_name* method.
finally `run` will forward all fields to `run_compiler`.
Fix unicode regexen with bytes::Regex
fixes#6005
The rationale for this is that since we wrote that lint, `bytes::Regex` was extended to be able to use unicode character classes.

changelog: [`invalid_regex`]: allow unicode character classes in bytes regex.
Fixes#5542.

declare them as `Box` in its Rust-side signature. However, the current

Downgrade rc_buffer to restriction
I think Arc\<Vec\<T\>\> and Arc\<String\> and similar are a totally reasonable data structure, as observed by others in the comments on [#6044](https://github.com/rust-lang/rust-clippy/pull/6044#event-3799579830) as well. Doing `Arc::make_mut(&mut self.vec).push(...)` or `Arc::make_mut(&mut self.string).push_str("...")` is a terrific and well performing copy-on-write pattern. Linting this with an enabled-by-default <kbd>performance</kbd> lint strikes me as an unacceptable false positive balance.
As of #6090 the documentation of this lint now contains:
> **Known problems:** This pattern can be desirable ...
which should indicate that we shouldn't be linting against correct, reasonable, well-performing patterns with an enabled-by-default lint.
Mentioning #6044, #6090.

Reinstate test for forbid(clippy::restriction)
In [this commit](5747c15961) coming from rust-lang/rust (#6126) the test for `#![forbid(clippy::restriction)]` was removed because some restriction lints were being allowed after the forbid.
This change reinstates the test for `forbid` by using a separate file.

Fix LitKind's byte buffer to use refcounted slice
While working on adding a new lint for clippy (see https://github.com/rust-lang/rust-clippy/pull/6044) for avoiding shared ownership of "mutable buffer" types (such as using `Rc<Vec<T>>` instead of `Rc<[T]>`), I noticed a type exported from rustc_ast and used by clippy gets caught by the lint. This PR fixes the exported type.
This PR includes the actual change to clippy too, but I will open a PR directly against clippy for that part (although it will currently fail to build there).
