- New ineffective_open_options had to be fixed.
- Now not raising an issue on missing `truncate` when `append(true)`
makes the intent clear.

Checks for the suspicious use of OpenOptions::create()
without an explicit OpenOptions::truncate().
create() alone will either create a new file or open an
existing file. If the file already exists, it will be
overwritten when written to, but the file will not be
truncated by default. If less data is written to the file
than it already contains, the remainder of the file will
remain unchanged, and the end of the file will contain old
data.
In most cases, one should either use `create_new` to ensure
the file is created from scratch, or ensure `truncate` is
called so that the truncation behaviour is explicit.
`truncate(true)` will ensure the file is entirely overwritten
with new data, whereas `truncate(false)` will explicitely
keep the default behavior.
```rust
use std::fs::OpenOptions;
OpenOptions::new().create(true).truncate(true);
```
The OpenTelemetry project's name is all one word (see https://opentelemetry.io),
so currently triggers a false positive in the `doc_markdown` lint.
The project is increasing rapidly in popularity, so it seems like a worthy
contender for inclusion in the default `doc_valid_idents` configuration.
I've also moved the existing "OpenDNS" entry earlier in the list, to restore
the alphabetical ordering of that "Open*" row.
The docs changes were generated using `cargo collect-metadata`.

[`useless_asref`]: check that the clone receiver is the parameter
Fixes#12135
There was no check for the receiver of the `clone` call in the map closure. This makes sure that it's a path to the parameter.

['arc_with_non_send_sync`] documentation edits
Arc's documentation uses the term "thread"; aligning to that terminology. Fix casing of "Rc".

Make `HirEqInterExpr::eq_block` take comments into account while checking if two blocks are equal
This PR:
- now makes `HirEqInterExpr::eq_block` take comments into account. Identical code with varying comments will no longer be considered equal.
- makes necessary adjustments to UI tests.
Closes#12044
**Lintcheck Changes**
- `match_same_arms` 53 => 52
- `if_same_then_else` 3 => 0
changelog: [`if_same_then_else`]: Blocks with different comments will no longer trigger this lint.
changelog: [`match_same_arms`]: Arms with different comments will no longer trigger this lint.

There are cases where the closure call is needed in some macros, this in
particular occurs when the closure has parameters. To handle this case,
we allow the lint when there are no parameters in the closure, or the
closure is outside a macro invocation.
fixes: #11274, #1553
changelog: FP: [`redundant_closure_call`] when closures with parameters
are passed in macros.
Improve help message for `search_is_some` lint
Fixes#11681.
Like mentioned in the issue, we tend to use the formulation "consider using", which we didn't in this case. I think it clears both the confusion and also makes help message more coherent overall.

Fix false positive in `PartialEq` check in `unconditional_recursion` lint
Fixes https://github.com/rust-lang/rust-clippy/issues/12133.
We needed to check for the type of the previous element <del>in case it's a field</del>.
EDIT: After some extra thoughts, no need to check if it's a field, just if it's the same type as `Self`.

Fix suggestion for `map_clone` lint on types implementing `Copy`

It was missing this check to suggest the correct method.

Remove giraffate from the reviewer rotation
I've been less active in Clippy recently because I'm so busy that I don't have time for maintaining Clippy in my spare time. So, I remove myself from the reviewer rotation once. I hope to come back again.
I'll reassign the PRs later.
changelog: none
One consequence is that errors returned by
`maybe_new_parser_from_source_str` now must be consumed, so a bunch of
places that previously ignored those errors now cancel them. (Most of
them explicitly dropped the errors before. I guess that was to indicate
"we are explicitly ignoring these", though I'm not 100% sure.)
