One of the links in the docs was being rendered as a literal
open-bracket followed by a single quote, instead of being transformed
into a link. Fix it to match the link earlier in the same paragraph.

`MethodSig` -> `FnSig` & Use it in `ItemKind::Fn`
In both AST & HIR, rename `MethodSig` to `FnSig` and then proceed to use it in `ItemKind::Fn` so that the overall structure is more regular.

miri: Rename to_{u,i}size to to_machine_{u,i}size
Having a function `to_usize` that does not return a (host) usize is somewhat confusing, so let's rename it.

rename Memory::get methods to get_raw to indicate their unchecked nature
Some recent Miri PRs started using these methods when they should not; this should discourage their use.
In fact we could make these methods private to the `interp` module as far as Miri is concerned -- with the exception of the `uninit` intrinsic which will hopefully go away soon. @bjorn3 @oli-obk does priroda need these methods? It would be great to be able to seal them away.
The code was previously suggesting `#[repr(C, packed, ...)]` for
incorrect uses of `repr` (e.g. `#[repr = "C"]`). This change suggests
the usage of `#[repr(C)]` instead.

ref #61286
Remove promotion candidate gathering and checking from `qualify_consts.rs`
This makes promotion candidate gathering and checking the exclusive domain of `promote_consts`, but the `QualifyAndPromoteConsts` pass is still responsible for both const-checking and creating promoted MIR fragments.
This should not be merged until the beta branches on Nov. 5.

In order that we can successfully later resolve paths in crates
which weren't loaded as a result of merely parsing the crate
we're documenting, we force the resolution of the path to each
crate before cloning the resolver to use later. Closes#66159

This makes `rustdoc` support `--extern-private` but treats it
the same as `--extern` which is useful for making the CLI more
similar to `rustc` to ease test suite integration.

rustc_target: inline abi::FloatTy into abi::Primitive.
This effectively undoes a small part of @oli-obk's #50967, now that the rest of the compiler doesn't use the `FloatTy` definition from `rustc_target`, post-#65884.
Improve math log documentation examples
using 2.0.log(2.0) in examples does not make it clear which is the base and number. This example makes it clear for programmers who take a glance at the example by following the calculation. It is more intuitive, and eliminates the need for executing the example in the playground.
rustc_metadata: Some reorganization of the module structure
The new structure of `rustc_metadata` (or rather its parts affected by the refactoring) is
```
├── lib.rs
└── rmeta
├── decoder
│ └── cstore_impl.rs
├── decoder.rs
├── encoder.rs
├── mod.rs
└── table.rs
```
(`schema` is renamed to `rmeta`.)
The code inside `rmeta` is pretty self-contained, so we can now privatize almost everything in this module instead of using `pub(crate)` which was necessary when all these modules accessed their neighbors in the old flat structure.
`encoder` and `decoder` work with structures defined by `rmeta`.
`table` is a part of `rmeta`.
`cstore_impl` actively uses decoder methods and exposes their results through very few public methods (`provide` and `_untracked` methods).

consistent handling of missing sysroot spans
Due to https://github.com/rust-lang/rust/issues/53081, sysroot spans (pointing to code in libcore/libstd/...) fails to print on some x86 runners. This consolidates the ignore directives for that and references the relevant issue.
I also did that for the generated derive-error-span tests -- but there the script and the tests were not entirely in sync any more since https://github.com/rust-lang/rust/pull/64151. Cc @estebank @varkor
Add `MaybeUninit` methods `uninit_array`, `slice_get_ref`, `slice_get_mut`
Eventually these will hopefully become the idiomatic way to work with partially-initialized stack buffers.
All methods are unstable. Note that `uninit_array` takes a type-level `const usize` parameter, so it is blocked (at least in its current form) on const generics.
Example:
```rust
use std::mem::MaybeUninit;
let input = b"Foo";
let f = u8::to_ascii_uppercase;
let mut buffer: [MaybeUninit<u8>; 32] = MaybeUninit::uninit_array();
let vec;
let output = if let Some(buffer) = buffer.get_mut(..input.len()) {
buffer.iter_mut().zip(input).for_each(|(a, b)| { a.write(f(b)); });
unsafe { MaybeUninit::slice_get_ref(buffer) }
} else {
vec = input.iter().map(f).collect::<Vec<u8>>();
&vec
};
assert_eq!(output, b"FOO");
```
Enhance the documentation of BufReader for potential data loss
This is (IMO) and enhancement of the `std::io::BufReader` documentation, that aims to highlight how relatively easy is to end up with data loss when improperly using an instance of this class.
This is following the issue I had figuring out why my application was loosing data, because I focused my attention on the word *multiple instances* of `BufReader` in its `struct` documentation, even if I ever only had one instance.
Link to the issue: https://github.com/tokio-rs/tokio/issues/1662
Stabilize --extern flag without a path.
This stabilizes the `--extern` flag without a path, implemented in #54116.
This flag is used to add a crate that may be found in the search path to the extern prelude. The intent of stabilizing this now is to change Cargo to emit this flag for `proc_macro` when building a proc-macro crate. This will allow the ability to elide `extern crate proc_macro;` for proc-macros, one of the few places where it is still necessary.
It is intended that Cargo may also use this flag for other cases in the future as part of the [std-aware work](https://github.com/rust-lang/wg-cargo-std-aware/). There will likely be some kind of syntax where users may declare dependencies on other crates (such as `alloc`), and Cargo will use this flag so that they may be used like any other crate. At this time there are no short-term plans to use it for anything other than proc-macro.
This will not help for non-proc-macro crates that use `proc_macro`, which I believe is not too common?
An alternate approach for proc-macro is to use the `meta` crate, but from my inquiries there doesn't appear to be anyone interested in pushing that forward. The `meta` crate also doesn't help with things like `alloc` or `test`.

Currently the `RUST_CONFIGURE_ARGS` variable apparently has a trailing
newline at the end of it due to the way it's configured in yaml. This
causes issues with MSVC's `install-clang.sh` step where the way the bash
syntax works out means that we drop the arg we're trying to add and it
doesn't actually get added!
The hopeful fix here is to tweak how we specify the yaml syntax to not
have a trailing newline, we'll see what CI says about this...
