Remove "execute" bit from lock file permissions
Previously, flock would set the "execute" bit on Rust lock files. That makes no sense.
This patch clears the "execute" bit on Rust lock files.
See issue #102531.
Add `Box<[T; N]>: TryFrom<Vec<T>>`
We have `[T; N]: TryFrom<Vec<T>>` (#76310) and `Box<[T; N]>: TryFrom<Box<[T]>>`, but not this combination.
`vec.into_boxed_slice().try_into()` isn't quite a replacement for this, as that'll reallocate unnecessarily in the error case.
**Insta-stable, so needs an FCP**
(I tried to make this work with `, A`, but that's disallowed because of `#[fundamental]` https://github.com/rust-lang/rust/issues/29635#issuecomment-1247598385)

Do not register placeholder `RegionOutlives` obligations when `considering_regions` is false
**NOTE:** I'm kinda just putting this up for discussion. I'm not certain this is correct...?
This was introduced in [`608625d`](608625dae9 (diff-6e54b18681342ec725d75591dbf384ad08cd73df29db00485fe51b4e90f76ff7R361)).
Interestingly, we only check `data.has_placeholders()` for `RegionOutlives`, and not for `TypeOutlives`... why? For the record, that different treatment between `RegionOutlives` and `TypeOutlives` is why the fix "The compiling succeeds when all `'a : 'b` are replaced with `&'a () : 'b`" in #100689 _"works"_, but it seems like an implementation detail considering this.
Also, why do we care about placeholder regions being registered if `considering_regions` is false? It doesn't seem to affect any UI tests, for example.

remote-test-server: Show command line arguments
The user of remote-test-server should get at least some minimal command line help as this is often started manually.

* Since it's used exclusively on source pages, no need to explicitly
select.
* No need to hide it when the sidebar is open, since it fills the whole
page.

Clarify the possible return values of `len_utf16`
`char::len_utf16` always return 1 or 2. Clarify this in the docs, in the same way as `char::len_utf8`.
Documentation BTreeMap::append's behavior for already existing keys
`BTreeMap::append` overwrites existing values with new ones. This commit adds explicit documentation for that.
