Rollup merge of #78476 - RalfJung:btree-alias, r=Mark-Simulacrum
fix some incorrect aliasing in the BTree

This line is wrong:
```
ptr::copy(slice.as_ptr().add(idx), slice.as_mut_ptr().add(idx + 1), slice.len() - idx);
```
When `slice.as_mut_ptr()` is called, that creates a mutable reference to the entire slice, which invalidates the raw pointer previously returned by `slice.as_ptr()`. (Miri currently misses this because raw pointers are not tracked properly.)

Rollup merge of #78437 - ssomers:btree_no_ord_at_node_level, r=Mark-Simulacrum
BTreeMap: stop mistaking node for an orderly place

A second mistake in #77612 was to ignore the node module's rightful comment "this module doesn't care whether the entries are sorted". And there's a much simpler way to visit the keys in order, if you check this separately from a single pass checking everything.

Rollup merge of #78026 - sunfishcode:symlink-hard-link, r=dtolnay
Define `fs::hard_link` to not follow symlinks.

POSIX leaves it [implementation-defined] whether `link` follows symlinks.
In practice, for example, on Linux it does not and on FreeBSD it does.
So, switch to `linkat`, so that we can pick a behavior rather than
depending on OS defaults.

Pick the option to not follow symlinks. This is somewhat arbitrary, but
seems the less surprising choice because hard linking is a very
low-level feature which requires the source and destination to be on
the same mounted filesystem, and following a symbolic link could end
up in a different mounted filesystem.

Rollup merge of #77640 - ethanboxx:int_error_matching_attempt_2, r=KodrAus
Refactor IntErrorKind to avoid "underflow" terminology

This PR is a continuation of #76455

# Changes

- `Overflow` renamed to `PosOverflow` and `Underflow` renamed to `NegOverflow` after discussion in #76455
- Changed some of the parsing code to return `InvalidDigit` rather than `Empty` for strings "+" and "-". https://users.rust-lang.org/t/misleading-error-in-str-parse-for-int-types/49178
- Carry the problem `char` with the `InvalidDigit` variant.
- Necessary changes were made to the compiler as it depends on `int_error_matching`.
- Redid tests to match on specific errors.

Correct unsigned equivalent of isize to be usize

See [#74913 (comment)](https://github.com/rust-lang/rust/issues/74913#issuecomment-722334456) for why this matters. Apparently it hasn't been used anywhere else, though CI will tell for sure.

Rollup merge of #76227 - CDirkx:const-poll, r=KodrAus
Stabilize `Poll::is_ready` and `is_pending` as const

Insta-stabilize the methods `is_ready` and `is_pending` of `std::task::Poll` as const, in the same way as [PR#76198](https://github.com/rust-lang/rust/pull/76198).

Possible because of the recent stabilization of const control flow.

Part of #76225.
