suggests `is_some_and` over `map().unwrap`
changelog: Enhancement: [`option_map_unwrap_or`] now considers the [`msrv`] config when creating the suggestion.
* modified option_map_unwrap_or lint to recognise when an `Option<T>` is mapped to an `Option<bool>` with false being used when `None` is detected; suggests the use of `is_some_and` instead
* msrv is set to 1.70.0 for this lint; when `is_some_and` was stabilised

[`question_mark`]: don't lint inside of `try` block
Fixes#8628.
Diff looks a bit noisy because I had to move the two functions into an impl, because they now need to access the structs `try_block_depth` field to see if they're inside a try block.

[`option_if_let_else`]: suggest `.as_ref()` if scrutinee is of type `&Option<_>`
Fixes#10729
`Option::map_or` takes ownership, so if matching on an `&Option<_>`, we need to suggest `.as_ref()` before calling `map_or` to get the same effect and to not cause a borrowck error.
changelog: [`option_if_let_else`]: suggest `.as_ref()`/`.as_mut()` if scrutinee is of type `&Option<_>`/`&mut Option<_>`
[`unused_async`]: don't lint if function is part of a trait
Fixes#10459.
We shouldn't lint if the function is part of a trait, because the user won't be able to easily remove the `async`, as this will then not match with the function signature in the trait definition

New lints ['`needless_pub_self`], [`pub_with_shorthand`] and [`pub_without_shorthand`]
Closes#10963Closes#10964
changelog: New lints ['`needless_pub_self`], [`pub_with_shorthand`] and [`pub_without_shorthand`]
Use substring matching for TESTNAME
Restores the previous behaviour of matching using a substring match rather than needing a full match

Add `BLESS` for compile-test and some cleanup
changelog: none
Allows passing the environment variable `BLESS` to bless tests, which is useful when you want to bless internal tests - `BLESS= cargo uitest -Finternal`
Also updates a place in the docs referring to `cargo dev bless` and removes some unused test deps
New lint [`needless_raw_string_hashes`]
Emits a warning when there are an extraneous number of hashes(?) around a raw string literal, for example `r##"I'm a "raw string literal"!"##` or `cr#"crunb"#`
Closes#10882
I think this could also fit in `style` as well, rather than `complexity`.
changelog: Add [`needless_raw_string_hashes`] and [`needless_raw_string`] lints
Don't lint code from external macros for 8 lints
Fixes#11008
changelog: [`unneeded_field_pattern`], [`redundant_pattern`], [`uneeded_wildcard_pattern`], [`double_neg`], [`separated_literal_suffix`], [`unseparated_literal_suffix`], [`mixed_case_hex_literals`], [`zero_prefixed_literal`]: Don't lint code from external macros
(wow, that's one hell of a changelog for such a small change...)
Port clippy away from compiletest to ui_test
Reasons to do this:
* runs completely on stable Rust
* is easier to extend with new features
* has its own dogfood test suite, so changes can be tested in [the `ui_test` repo](https://github.com/oli-obk/ui_test)
* supports dependencies from crates.io without having to manually fiddle with command line flags
* supports `ui-cargo`, `ui`, `ui-toml` out of the box, no need to find and run the tests ourselves
One thing that is a big difference to `compiletest` is that if a test emits *any* error, you need to mark all of them with `//~ ERROR:` annotations. Since many clippy tests did not have annotations, I changed many lints to be `warn` in their test so that only the `stderr` output is tested.
TODO:
* [ ] check that this still works as a subtree in the rustc repo
changelog: none
<!-- changelog_checked -->
Note: at present the latest changes needed for clippy are only available as a git dependency, but I expect to publish a new crates.io version soon
