This is a fairly simple special case of --default-eetting. We must
set both "theme" and "use-system-theme".
Providing it separately enables us to document a way to set the theme
without expoosing the individual settings keywords, which are quite
complex.

We just plumb through what the user tells us.
This is flagged as unstable, mostly because I don't understand the
compatibility rules that rustdoc obeys for local storage data, and how
error handling of invalid data works.
We collect() the needed HashMap from Vec of Vecs of (key, value)
pairs, so that there is a nice place to add new more-specific options.
It would have been possible to use Extend::extend but doing it this
way ensures that all the used inputs are (and will stay) right next to
each other.

rustdoc has various user-configurable preferences. These are recorded
in web Local Storage (where available). But we want to provide a way
to configure the default default, including for when web storage is
not available.
getSettingValue is the function responsible for looking up these
settings. Here we make it fall back some in-DOM data, which
ultimately comes from RenderOptions.default_settings.
Using HTML data atrtributes is fairly convenient here, dsspite the
need to transform between snake and kebab case to avoid the DOM
converting kebab case to camel case (!)
We cache the element and dataset lookup in a global variable, to
ensure that getSettingValue remains fast.
The DOM representation has to be in an element which precedes the
inclusion of storage.js. That means it has to be in the <head> and we
should not use an empty <div> as the container (although most browsers
will accept that). An empty <script> element provides a convenient
and harmless container object. <meta> would be another possibility
but runs a greater risk of having unwanted behaviours on weird
browsers.
We trust the RenderOptions not to contain unhelpful setting names,
which don't fit nicely into an HTML attribute. It's awkward to quote
dataset keys.

Implement -Z function-sections=yes|no
This lets rustc users tweak whether all functions should be put in their own TEXT section, using whatever default value the target defines if the flag is missing.
I'm having fun experimenting with musl libc and trying to implement the start symbol in Rust, that means avoiding code that requires relocations, and AFAIK putting everything in its own section makes the toolchain generate `GOTPCREL` relocations for symbols that could use plain old PC-relative addressing (at least on `x86_64`) if they were all in the same section.
Currently, storage.js and main.js have many open-coded calls to
getCurrentValue for "rustdoc-" values, but these are settings and
should be handled by getSettingValue.
So make getSettingValue part of storage.js (where everyone can call
it) and use it everywhere.
No functional change yet. We are going to make getSettingValue do
something more sophisticated in a moment.

Add checksums cache to build-manifest
During the release process we're currently calculating the SHA256 of each file three times:
1. In `build-manifest`, to fill the `hash = "f00"` keys of the manifests.
2. In `promote-release`, to generate the `.sha256` files.
3. In `promote-release`, to generate the `.asc` GPG signatures.
Calculations 1. and 2. could be merged into a single one if there was a way for `build-manifest` to pass the checksums it generated over to `promote-release`. Unfortunately calculation 3. can't be merged as GPG requires extra metadata to be hashed.
This PR adds support for merging 1. and 2. by creating the `BUILD_MANIFEST_CHECKSUM_CACHE` environment variable, which points to a JSON file storing a cache of all the calculated checksums. `build-manifest` will load it at startup and avoid generating existing checksums, and it will dump its internal checksums cache into it when it exits successfully.
This PR also allows to run `build-manifest` multiple times without the need to wait for checksums to be calculated in the following invocations. The speedup will allow to work torwards a fix for https://github.com/rust-lang/promote-release/issues/15 without impacting the release process duration nor our storage costs.
This PR can be reviewed commit-by-commit.
r? `@Mark-Simulacrum`
This commit adds to the generated manifest all files we ship that are
not rustup components, namely:
* Source code tarballs (rustc-{channel}-src.tar.xz)
* Windows installers (rust-{channel}-{target}.msi)
* macOS installers (rust-{channel}-{target}.pkg)
Those files are included in a new "artifacts" table of the manifest, to
avoid interfering with existing rustup installations.
Iterate over the smaller list
If there are two lists of different sizes,
iterating over the smaller list and then
looking up in the larger list is cheaper
than vice versa, because lookups scale
sublinearly.
resolve: private fields in tuple struct ctor diag
Fixes#75906.
This PR improves the diagnostic emitted when a tuple struct is being constructed which has private fields so that private fields are labelled and the message is improved.

Add const_fn in generics test
Adds a test that constant functions in generic parameters work properly. I was surprised this works, but I also to turbofish the constant in main, otherwise it didn't infer properly:
```
let v: ConstU32<3> = ...
```
Did not work as I expected, which I can highlight in the test if that's the intended behaviour.

Tweak invalid `fn` header and body parsing
* Rely on regular "expected"/"found" parser error for `fn`, fix#77115
* Recover empty `fn` bodies when encountering `}`
* Recover trailing `>` in return types
* Recover from non-type in array type `[<BAD TOKEN>; LEN]`
check object safety of generic constants
As `Self` can only be effectively used in constants with `const_evaluatable_checked` this should not matter outside of it.

Move "mutable thing in const" check from interning to validity
This moves the check for mutable things (such as `UnsafeCell` or `&mut`) in a`const` from interning to validity. That means we can give more targeted error messages (pointing out *where* the problem lies), and we can simplify interning a bit.
Also fix the interning mode used for promoteds in statics.

Suggest calling await on method call and field access
When encountering a failing method or field resolution on a `Future`,
look at the `Output` and try the same operation on it. If successful,
suggest calling `.await` on the `Future`.
This had already been introduced in #72784, but at some point they
stopped working.
Built on top of #78214, only last commit is relevant.

Uplift `temporary-cstring-as-ptr` lint from `clippy` into rustc
The general consensus seems to be that this lint covers a common enough mistake to warrant inclusion in rustc.
The diagnostic message might need some tweaking, as I'm not sure the use of second-person perspective matches the rest of rustc, but I'd like to hear others' thoughts on that.
(cc #53224).
