The default illumos shell ("sh" in the default PATH) is ksh93, rather
than bash, and does not support constructs like "local" that came from
bash.  The bootstrap function for invoking "install.sh" scripts should
use "bash" explicitly there to avoid issues.

This switches from JS-generated toggles to using the HTML <details> tag
for expanding and collapsing entries in the "Implementors" section.

These were made public in 3105bcf. This
is so long ago I doubt anyone remembers why they're public. No one uses
them, including in-tree tools.

It's always `tcx.crate_name(LOCAL_CRATE)`, it doesn't need to be passed
in separately.

Using `fuse` on an iterator that incorrectly implements
`FusedIterator` does not fuse the iterator. This commit adds a
note about this in the documentation of this method to increase
awareness about this potential issue (esp. when relying on fuse
in unsafe code).

implement `TrustedRandomAccess` for `Take` iterator adapter

`TrustedRandomAccess` requires the iterator length to fit within `usize`. `take(n)` only constrains the upper bound of an iterator. So if the inner is `TrustedRandomAccess` (which already implies a finite length) then so can be `Take`.

bootstrap: use bash on illumos to run install scripts

The default illumos shell ("sh" in the default PATH) is ksh93, rather
than bash, and does not support constructs like "local" that came from
bash.  The bootstrap function for invoking "install.sh" scripts should
use "bash" explicitly there to avoid issues.

Use details tag for trait implementors.

Part of rust-lang#83332 and following on from rust-lang#83337 and rust-lang#83355.

This removes one category of JS-generated toggles (implementors), and replaces them with a `<details>` tag. This simplifies the JS, and fixes some bugs where things that were supposed to be hidden by the toggle were not hidden. Compare https://hoffman-andrews.com/rust/details-implementors/std/io/trait.Read.html#impl-Read vs https://doc.rust-lang.org/nightly/std/io/trait.Read.html#implementors.

This introduces a `left: -23px` to put the toggle in the correct place, matching the current style for `.collapse-toggle`.

It's worth noting this introduces a slight behavior change: since the entire line is now a `<summary>`, any part of the line is clickable. So for instance, in `impl Read for File`, clicking `impl` or `for` will collapse / expand the docs. Clicking `Read` or `File` still links to the appropriate documentation as before.

Make a few functions private

These were made public in 3105bcf. This
is so long ago I doubt anyone remembers why they're public. No one outside rustc_session uses
them, including in-tree tools.
