Monomorphize less code in fs::{read|write}
Since the generic-ness is only for the as_refs, might as well have std just compile the important part once instead of on every use.
Fix search results interactions
The bug is visible when you search for "none": the second tab is empty and therefore it messes with the classes. Then when you try to use arrows on the third tab, it just crashes (because only 2 "search-results" are present and you're on tab 3).

Modify doctest's auto-`fn main()` to allow `Result`s
This lets the default `fn main()` ~~return `impl Termination`~~ unwrap Results, which allows the use of `?` in most tests without adding it manually. This fixes#56260
~~Blocked on `std::process::Termination` stabilization.~~
Using `Termination` would have been cleaner, but this should work OK.
rustdoc: Don't modify library path for doctests
It shouldn't be needed anymore because doctests are no longer compiled with `prefer-dynamic` (since #54939).

This keeps the slice based iteration and updates the iterator
state after each slice. It also uses a loop to reduce the amount
of code.
This uses unsafe code, so some thorough review would be
appreciated.
ci: fix docker cache hash collision
#58416 uncovered a bug in our caching for docker images: if the image `foo` pulls files from the image `bar` and a file in `bar` changed, the hash of `foo` will be the same even though it should be different. In that PR's case, `dist-i686-linux` pulls scripts from `dist-x86_64-linux`, and the PR only changed those scripts, causing an hash collision for `dist-i686-linux`.
We have to fix this, since the image will be rebuilt every time bors switches from testing master to testing beta/stable (and when it switches back), making CI way more painful than it currently is.
The approach used by this PR is to just include all the files in `src/ci/docker` in the hash. It's a bit heavy-handed and it will cause a rebuild of all the images every time a single image changes, but it's the best I can think of.

Before this commit the hash used to cache docker images was calculated
from the image's files and the files in the scripts/ directory. This
worked fine when all the files used by an image were in those
directories, but some images pull files from other images, causing hash
collisions in some cases.
This commit changes the hash to include the files of all the docker
images, causing a rebuild of all the images when a single one changes.
That's a bit heavy-handed, but we have no way to track which files an
image pulls in and hash collisions are really painful to deal with.
