- Implement `field_reassign_with_default` as a `LateLintPass`
- Avoid triggering `default_trait_access` on a span already linted by
`field_reassigned_with_default`
- Merge `default_trait_access` and `field_reassign_with_default` into
`Default`

- Fixes#568
std::format and core::write macros' docs linked to core::fmt for format string reference, even though only std::fmt has format string documentation and the link titles were std::fmt.
Constantify more BTreeMap and BTreeSet functions
Just because we can:
- `BTreeMap::len`
- `BTreeMap::is_empty`
- `BTreeSet::len`
- `BTreeSet::is_empty`
Note that I put the `const` under `const_btree_new`, because I don't think their is a need to create another feature flag for that.

x.py setup: Create config.toml in the current directory, not the top-level directory

make exp_m1 and ln_1p examples more representative of use
With this PR, the examples for `exp_m1` would fail if `x.exp() - 1.0` is used instead of `x.exp_m1()`, and the examples for `ln_1p` would fail if `(x + 1.0).ln()` is used instead of `x.ln_1p()`.
Add std::panic::panic_any.
The discussion of #67984 lead to the conclusion that there should be a macro or function separate from `std::panic!()` for throwing arbitrary payloads, to make it possible to deprecate or disallow (in edition 2021) `std::panic!(arbitrary_payload)`.
Alternative names:
- `panic_with!(..)`
- ~~`start_unwind(..)`~~ (panicking doesn't always unwind)
- `throw!(..)`
- `panic_throwing!(..)`
- `panic_with_value(..)`
- `panic_value(..)`
- `panic_with(..)`
- `panic_box(..)`
- `panic(..)`
The equivalent (private, unstable) function in `libstd` is called `std::panicking::begin_panic`.
I suggest `panic_any`, because it allows for any (`Any + Send`) type.
_Tracking issue: #78500_
This is mostly motivated by docs.rs. It's really weird
when arrow keys work in the top dropdown menu, but don't work
in other dropdown menus on the same page.
Disable and enable when not specifically explained were not clear to me
as an English language speaker, but I was able to figure it out fairly
easily due to the examples having A/W, which I assumed meant `allow` and
`warn`. I removed both words to be sure it was clear as well as
extending the note on what deny means. It now includes a statement on
exactly what each word means.
