Warn if an item coming from more recent version than MSRV is used
Part of https://github.com/rust-lang/rust-clippy/issues/6324.
~~Currently, the lint is not working for the simple reason that the `stable` attribute is not kept in dependencies. I'll send a PR to rustc to see if they'd be okay with keeping it.~~
EDIT: There was actually a `lookup_stability` function providing this information, so all good now!

bump version to 1.77 and run cargo collect-metadata
Change `,` to `;` in `conf.rs`
expending lint [`blocks_in_if_conditions`] to check match expr as well
closes: #11814
changelog: rename lint `blocks_in_if_conditions` to [`blocks_in_conditions`] and expand it to check blocks in match scrutinees
Now `declare_interior_mutable_const` and `borrow_interior_mutable_const` respect the `ignore-interior-mutability` configuration entry
Fix#10537
changelog: Now `declare_interior_mutable_const` and `borrow_interior_mutable_const` respect the `ignore-interior-mutability` configuration entry
Deserialize `Msrv` directly in `Conf`
Gives the error a span pointing to the invalid config value
Also puts `Conf` itself in the `OnceLock` rather than just the `Msrv` for [the `register_late_mod_pass` work](https://github.com/rust-lang/rust/pull/116731) since it will be used from two different callbacks
changelog: none
side effect for `enum_variants`:
use .first() instead of .get(0) in enum_variants lint
move to_camel_case to str_util module
move module, enum and struct name repetitions check to a single file `item_name_repetitions`
rename enum_variants threshold config option
changelog: Now `declare_interior_mutable_const` and `borrow_interior_mutable_const` respect the `ignore-interior-mutability` configuration entry

`impl_trait_in_params` now supports impls and traits
Before this PR, the lint `impl_trait_in_params`. This PR gives the lint support for functions in impls and traits. (Also, some pretty heavy refactor)
fixes#11548
changelog:[`impl_trait_in_params`] now supports `impl` blocks and functions in traits
fix fp when [`undocumented_unsafe_blocks`] not able to detect comment on globally defined const/static variables
fixes: #11246
changelog: fix detection on global variables for [`undocumented_unsafe_blocks`]
Add config flag for reborrows in explicit_iter_loop
This PR adds a config flag for enforcing explicit into iter lint for reborrowed values. The config flag, `enforce_iter_loop_reborrow`, can be added to clippy.toml files to enable the linting behaviour. By default the reborrow lint is disabled.
fixes: #11074
changelog: [`explicit_iter_loop`]: add config flag `enforce_iter_loop_reborrow` to disable reborrow linting by default
This commit adds a config flag for enforcing explicit into iter lint
for reborrowed values. The config flag, enforce_iter_loop_reborrow, can be
added to clippy.toml files to enable the linting behaviour. By default
the lint is not enabled.
"try this" -> "try"
Current help messages contain a mix of "try", "try this", and one "try this instead". In the spirit of #10631, this PR adopts the first, as it is the most concise.
It also updates the `lint_message_conventions` test to catch cases of "try this".
(Aside: #10120 unfairly contained multiple changes in one PR. I am trying to break that PR up into smaller pieces.)
changelog: Make help messages more concise ("try this" -> "try").
Add `needless_if` lint
first off: Sorry about the large diff. Seems a ton of tests do this (understandably so).
this is basically everything I wanted in #10868, while it doesn't lint *all* unnecessary empty blocks, it lints needless if statements; which are basically the crux of the issue (for me) anyway. I've committed code that includes this far too many times 😅 hopefully clippy can help me out soon
closes#10868
changelog: New lint [`needless_if`]
Add spans to `clippy.toml` error messages
Adds spans to errors and warnings encountered when parsing `clippy.toml`.
changelog: Errors and warnings generated when parsing `clippy.toml` now point to the location in the TOML file the error/warning occurred.
Add configuration for `semicolon_block` lints
Does exactly what it says on the tin, suggests moving a block's final semicolon inside if it's multiline and outside if it's singleline.
I don't really like how this is implemented so I'm not too sure if this is ready yet. Alas, it might be ok.
