add -Zexport-executable-symbols to unstable book
This flag has been extremely useful to me, but it's hard to discover. The text contains a bunch of terms that hopefully a search engine will pick up on when someone searches for this functionality.
Clippy Fix array-size-threshold config deserialization error
Complementary PR to https://github.com/rust-lang/rust/pull/108673 in order to also get this into the **next** beta.

Support allocations with non-Box<[u8]> bytes
This is prep work for allowing miri to support passing pointers to C code, which will require `Allocation`s to be correctly aligned. Currently, it just makes `Allocation` generic and plumbs the necessary changes through the right places.
The follow-up to this will be adding a type in the miri interpreter which correctly aligns the bytes, using that for the Miri engine, then allowing Miri to pass pointers into these allocations to C calls.
Based off of #100467, credit to ```@emarteca``` for the code

Highlight whole expression for E0599
Fixes#108603
This adds a secondary label to highlight the whole expression leading to the error. It also prevents empty labels being recognised as 'unexpected' by compiletest - otherwise, tests with NOTE annotations would pick up empty labels.

Restrict `#[rustc_box]` to `Box::new` calls
Currently, `#[rustc_box]` can be applied to any call expression with a single argument. This PR only allows it to be applied to calls to `Box::new`
Add support for QNX Neutrino to standard library
This change:
- adds standard library support for QNX Neutrino (7.1).
- upgrades `libc` to version `0.2.139` which supports QNX Neutrino
`@gh-tr`
⚠️ Backtraces on QNX require https://github.com/rust-lang/backtrace-rs/pull/507 which is not yet merged! (But everything else works without these changes) ⚠️
Tested mainly with a x86_64 virtual machine (see qnx-nto.md) and partially with an aarch64 hardware (some tests fail due to constrained resources).
Make `x doc --open` work on every book
Before this PR, the `--open` flag had to be configured explicitly for every book, and most of them didn't configure it, resulting in the flag silently failing in all but two books.
In this PR, the code to check for the `--open` flag is in the underlying `RustbookSrc` step rather than all the individual steps. This is done by passing the parent step as a field of `RustbookSrc`, so that we can check for the correct step in `maybe_open_in_browser`.
This was part of a larger change that in the end wasn't worth it. Still, I think it could be useful as-is.

Remove `from` lang item
It was probably a leftover from the old `?` desugaring but anyways, it's unused now except for clippy, which can just use a diagnostics item.
