Implement reading and writing atomically at certain offsets
These functions allow to read from and write to a file in one atomic
action from multiple threads, avoiding the race between the seek and the
read.
The functions are named `{read,write}_at` on non-Windows (which don't
change the file cursor), and `seek_{read,write}` on Windows (which
change the file cursor).

Use workspaces and switch to a single Cargo.lock.
This involves hacking the code used to run cargo test on various

be tested. This change implements a blacklist, since that will catch new

Fix rustbuild per-target musl root
In #36292, support was added to target musl libc for ARM targets using rustbuild. Specifically, that change allowed the addition of per-target `musl-root` options in the rustbuild `config.toml` so that multiple targets depending on musl could be built. However, that implementation contained a couple of omissions: the `musl-root` option was added to the config, but was never added to the TOML parsing, and therefore was not actually being loaded from `config.toml`. This PR rectifies that.
Using these changes and a heavily modified version of the buildbot Docker container, I have been able to build rust targeting `armv7-unknown-linux-musleabihf` and have successfully run the binaries on a Raspberry Pi 3. I'm also planning to test `arm-unknown-linux-musleabi` and `arm-unknown-linux-musleabihf` systems, but have no reason to believe that this change would not simply work on those targets.

Restore `DISCONNECTED` state in `oneshot::Packet::send`
Closes #32114
I'm not sure if this is the best approach, but the current action of swapping `DISCONNECTED` with `DATA` seems wrong. Additionally, it is strange that the `send` method (and others in the `oneshot` module) takes `&mut self` despite performing atomic operations, as this requires extra discipline to avoid data races and lets us use methods like `AtomicUsize::get_mut` instead of methods that require a memory ordering.

Refactoring/bugfixing around definitions for struct/variant constructors
https://github.com/rust-lang/rust/commit/d917c364ad0edfa441e5c219da1b00511b976789 separates definitions for struct/variant constructors living in value namespace from struct/variant type definitions.
https://github.com/rust-lang/rust/commit/adfb37827b3a52a83dd11d5781e5b492714a5d4c fixes cross-crate resolution of reexports reexporting half-items, like struct constructors without struct type or types without constructor. Such reexports can appear due to glob shadowing.
Resolution now is not affected by the order in which items and reexports are decoded from metadata (cc https://github.com/rust-lang/rust/issues/31337#issuecomment-183996263). `try_define` is not used during building reduced graph anymore.
500 lines of this PR are tests for this exotic situation, the remaining line diff count is actually negative! :)
https://github.com/rust-lang/rust/commit/c695d0c8756a87c0708b97b7e277b6a3f4712b97 (and partially https://github.com/rust-lang/rust/commit/aabf132de04643602ec17b6abab9e276366d9c6d) moves most of pattern resolution checks from typeck to resolve (except those checking for associated items), uses the same wording for pattern resolution error messages from both typeck and resolve and makes the messages more precise.
https://github.com/rust-lang/rust/commit/11e3524e5afa4ac1b04aece67fb683f078e63f37 fixes seemingly incorrectly set `NON_ZERO_SIZED` attributes for struct/variant ctors in const eval.
https://github.com/rust-lang/rust/commit/4586fea2531054d9b25f8663f1ba4b32b07c11c2 eliminates `ty::VariantKind` in favor of `def::CtorKind`. The logic is that variant kinds are irrelevant for types, they make sense only when we deal with constructor functions/constants. Despite that `VariantDefData` still keeps a copy of `CtorKind`, but it's used only for various kinds of pretty-printing (and for storing in metadata).
https://github.com/rust-lang/rust/commit/aabf132de04643602ec17b6abab9e276366d9c6d is mostly a cleanup of various impossible or improperly used definitions, and other small definition cleanups.

looks like LLVM's default armv7 target enables NEON so we'd otherwise have to
pass `-neon`, but we're already enabling armv7 with `+v7` supposedly, so let's
try just telling LLVM that the armv7 target is arm and then enable features
selectively.
