ccd6513c67 Additional doc links and explanation of Wake.
This is intended to clarify:

* That `Wake` exists and can be used instead of `RawWaker`.
* How to construct a `Waker` when you are looking at `Wake`
  (which was previously only documented in the example).

038c6e046c refactor: make waker mandatory.
This also removes
* impl From<&Context> for ContextBuilder
* Context::try_waker()

The from implementation is removed because now that
wakers are always supported, there are less incentives
to override the current context. Before, the incentive
was to add Waker support to a reactor that didn't have
any.

additional advice on how to `#[cfg]` for it.

Rollup merge of #79285 - yoshuawuyts:stabilize-arc_mutate_strong_count, r=m-ou-se
Stabilize Arc::{increment,decrement}_strong_count

Tracking issue: https://github.com/rust-lang/rust/issues/71983

Stabilizes `Arc::{incr,decr}_strong_count`, enabling unsafely incrementing an decrementing the Arc strong count directly with fewer gotchas. This API was first introduced on nightly six months ago, and has not seen any changes since. The initial PR showed two existing pieces of code that would benefit from this API, and included a change inside the stdlib to use this.

Given the small surface area, predictable use, and no changes since introduction, I'd like to propose we stabilize this.

c819a4c025 Don't mark ineffective_unstable_trait_impl as an internal lint
It's not an internal lint:
- It's not in the rustc::internal lint group
- It's on unconditionally, because it actually lints `staged_api`, not
  the compiler

This fixes a bug where `#[deny(rustc::internal)]` would warn that
`rustc::internal` was an unknown lint.
