needless_collect: Lint cases with type annotations for indirect usage and recognize `BinaryHeap`
fixes#7110

Move all `sys::ext` modules to `os`
This PR moves all `sys::ext` modules to `os`, centralizing the location of all `os` code and simplifying the dependencies between `os` and `sys`.
Because this also removes all uses `cfg_if!` on publicly exported items, where after #81969 there were still a few left, this should properly work around https://github.com/rust-analyzer/rust-analyzer/issues/6038.

Update BARE_TRAIT_OBJECT and ELLIPSIS_INCLUSIVE_RANGE_PATTERNS to errors in Rust 2021
This addresses https://github.com/rust-lang/rust/pull/81244 by updating two lints to errors in the Rust 2021 edition.

[single_char_pattern] add strip_prefix and strip_suffix
Title says it all. Adjusted ui tests.
I added the second commit in case you don't like that I moved that table into `single_char_pattern.rs` directly. I don't see any reason why it shouldn't be in that file. It isn't used anywhere else.
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: add strip_prefix and strip_suffix to single_char_pattern lint
`Conf` macro improvements part 2
changelog: none
Follow-up to #7150
I made the default value required again for `define_Conf!` so that it can be parsed by the magic Python. I guess it's just as well for readability.

`Conf` macro improvements
changelog: Allow `default_trait_access` in macros
Mainly this is a change to use serde as in [Manually implementing Deserialize for a struct](https://serde.rs/deserialize-struct.html), which opens the door for a cleaner implementation overall.
* Allow `default_trait_access` in macros (tangential, but used in this PR)
* Deserialize into `TryConf { conf, errors }` instead of using a global `ERRORS` variable.
* Improve the `define_Conf!` macro
* Remove the redundant string literal `(name, "name", ..)`
* Support deprecated configs with `#[conf_deprecated(message)]`. Message shows in error.
* Make the default value optional. Use `Default::default()` if omitted.
* Invalid config value error now shows the key (see test output)
* Cleaner `impl Default for Conf` (no `toml::from_str("")`)
while_immutable_cond: check condition for mutation
This fixes#6689 by also checking the bindings mutated in the condition, whereas it was previously only checked in the loop body.

changelog: Fix FP in [`while_immutable_cond`] where mutation in the loop variable wasn't picked up.
`implicit_return` improvements
fixes: #6940
changelog: Fix `implicit_return` suggestion for async functions
changelog: Improve `implicit_return` suggestions when returning the result of a macro
changelog: Check for `break` expressions inside a loop which are then implicitly returned
changelog: Allow all diverging functions in `implicit_return`, not just panic functions
Implement RFC 1260 with feature_name `imported_main`.
This is the second extraction part of #84062 plus additional adjustments.
This (mostly) implements RFC 1260.
However there's still one test case failure in the extern crate case. Maybe `LocalDefId` doesn't work here? I'm not sure.

Remove leftover plugin conf_file code
changelog: none
Removes dead code that used to support the following syntax:
```rust
#![plugin(clippy(conf_file="path/to/clippy's/configuration"))]
```
RLS (and others?) will need to remove the `&[]` from `clippy_lints::read_conf(&[], sess)`.

Implement `x.py test src/tools/clippy --bless`
- Add clippy_dev to the rust workspace
Before, it would give an error that it wasn't either included or
excluded from the workspace:
```
error: current package believes it's in a workspace when it's not:
current: /home/joshua/rustc/src/tools/clippy/clippy_dev/Cargo.toml
workspace: /home/joshua/rustc/Cargo.toml
this may be fixable by adding `src/tools/clippy/clippy_dev` to the `workspace.members` array of the manifest located at: /home/joshua/rustc/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.
```
- Change clippy's copy of compiletest not to special-case
rust-lang/rust. Using OUT_DIR confused `clippy_dev` and it couldn't find
the test outputs. This is one of the reasons why `cargo dev bless` used
to silently do nothing (the others were that `CARGO_TARGET_DIR` and
`PROFILE` weren't set appropriately).
- Run clippy_dev on test failure
I tested this by removing a couple lines from a stderr file, and they
were correctly replaced.
- Fix clippy_dev warnings
Don't rebuild rustdoc and clippy after checking bootstrap
This works by unconditionally passing -Z unstable-options to the
compiler. This has no affect in practice since bootstrap doesn't use
`deny(rustc::internal)`.
Fixes https://github.com/rust-lang/rust/issues/82461.
