This requires avoiding `quote_...!` for constructing the parts of the
__test module, since that stringifies and reinterns the idents, losing
the special gensym'd nature of them. (#15962.)
I _think_ this is the right place to introduce strings. It's a bit hard to talk about without understanding pointers and ownership, but you need to have some idea of what's going on...
I wasn't 100% sure of what level of detail I wanted to go into things here. For example, 1:1 vs M:N tasks seems like a better distinction to leave to the Guide.
This does a few things:
- remove references to ~[] and the OwnedVector trait, which are both
obsolete
- correct the docs to say that this is the slice module, not the vec
module
- add a sentence pointing out that vectors are distinct from Vec
- remove documentation on Vec.
closes#15459
This leaves the `Share` trait at `std::kinds` via a `#[deprecated]` `pub use`
statement, but the `NoShare` struct is no longer part of `std::kinds::marker`
due to #12660 (the build cannot bootstrap otherwise).
All code referencing the `Share` trait should now reference the `Sync` trait,
and all code referencing the `NoShare` type should now reference the `NoSync`
type. The functionality and meaning of this trait have not changed, only the
naming.
Closes#16281

Made INVALID_HANDLE_VALUE actually a HANDLE.
Removed all useless casts during INVALID_HANDLE_VALUE comparisons.

Introduce syntax for lifetime bounds like `'b:'a`, meaning `'b outlives 'a`. Syntax currently does nothing but is needed for full fix to #5763. To use this syntax, the issue_5763_bootstrap feature guard is required.

Simplifying the code of methods: `nth`, `fold`, `rposition`, and iterators: `Filter`, `FilterMap`, `SkipWhile`.
```
before
test iter::bench_multiple_take ... bench: 15 ns/iter (+/- 0)
test iter::bench_rposition ... bench: 349 ns/iter (+/- 94)
test iter::bench_skip_while ... bench: 158 ns/iter (+/- 6)
after
test iter::bench_multiple_take ... bench: 15 ns/iter (+/- 0)
test iter::bench_rposition ... bench: 314 ns/iter (+/- 2)
test iter::bench_skip_while ... bench: 107 ns/iter (+/- 0)
```
@koalazen has the code for `Skip`.
Once #16011 is fixed, `min_max` could use a for loop.
