Don't auto-hide inherent impls even if `rustdoc-collapse == true`.
This PR changes the auto-collapse behavior when a page is first loaded:
* Inherent impls will never be collapsed by default (new behavior).
* Trait impls will always be collapsed by default, same as before.
* Other items are collapsed according to localStorage, same as before.
This should be much more useful since there is no hint what the content of a collapsed inherent impl would be (try to collapse everything in https://doc.rust-lang.org/std/vec/struct.Vec.html and guess where a method like `try_reserve` or `splice` would be).
Manually clicking the global [-]/[+] will still collapse/expand everything.
Replace `core::iter::AlwaysOk<T>` by `Result<T, !>`
#43278 has been fixed, so we don't need this struct anymore.
(Actually we don't even need `.unwrap()` thanks to `#![feature(exhaustive_patterns)]`)
Make parse_seq_to_end and parse_path public
(see SergioBenitez/Rocket#660, rust-lang/rust#51265)
Rocket currently uses `parse_seq_to_end` and `parse_path` in its codegen macros. Assuming I tested correctly, this is the minimal set of methods that are currently necessary to build Rocket again. I would be happy to add documentation of this and Rocket's other usages, if desired.
Fix for $crate var normalization in proc macro for externally defined macros
Fixes#51331, a bug that has existed in at least *some* form for a year and a half.
The PR includes the addition of a `fold_qpath` method to `syntax::fold::Folder`. Overriding this method is useful for folds that modify paths in a way that invalidates indices (insertion or removal of a component), as it provides the opportunity to update `qself.position` in `<A as B>::C` paths. I added it because the bugfix is messy without it.
(unfortunately, grepping around the codebase, I did not see anything else that could use it.)
Make span_fatal and parse_block public
span_fatal and parse_block were made private in #51265. These methods are used in stainless.

[futures] add a few blanket impls to std
these were defined in the futures crate, but with the core definitions moving to std these would need to move too.
