* count_ones/zeros, trailing_ones/zeros return u32, not usize
* rotate_left/right take u32, not usize
* RADIX, MANTISSA_DIGITS, DIGITS, BITS, BYTES are u32, not usize
Doesn't touch pow because there's another PR for it.

* The lint visitor's visit_ty method did not recurse, and had a
reference to the now closed #10894
* The newly enabled recursion has only affected the `deprectated` lint
which now detects uses of deprecated items in trait impls and
function return types
* Renamed some references to `CowString` and `CowVec` to `Cow<str>` and
`Cow<[T]>`, respectively, which appear outside of the crate which
defines them
* Replaced a few instances of `InvariantType<T>` with
`PhantomData<Cell<T>>`
* Disabled the `deprecated` lint in several places that
reference/implement traits on deprecated items which will get cleaned
up in the future
* Disabled the `exceeding_bitshifts` lint for
compile-fail/huge-array-simple test so it doesn't shadow the expected
error on 32bit systems
* Unfortunately, this means that if a library declares
`#![deny(deprecated)]` and marks anything as deprecated, it will have
to disable the lint for any uses of said item, e.g. any impl the now
deprecated item
For any library that denies deprecated items but has deprecated items
of its own, this is a [breaking-change]

This commits blanket marks the API of the `std::process` module as `#[stable]`.
The module's API is very similar to the old `std::old_io::process` API and has
generally had quite a bit of time to bake both before and after the new module
landed.

This changes the type of some public constants/statics in libunicode.
Notably some `&'static &'static [(char, char)]` have changed
to `&'static [(char, char)]`. The regexp crate seems to be the
sole user of these, yet this is technically a [breaking-change]

This is an implementation of RFC 899 and adds stdio functionality to the new
`std::io` module. Details of the API can be found on the RFC, but from a high
level:
* `io::{stdin, stdout, stderr}` constructors are now available. There are also
`*_raw` variants for unbuffered and unlocked access.
* All handles are globally shared (excluding raw variants).
* The stderr handle is no longer buffered.
* All handles can be explicitly locked (excluding the raw variants).
The `print!` and `println!` machinery has not yet been hooked up to these
streams just yet. The `std::fmt::output` module has also not yet been
implemented as part of this commit.

The one modification made to the API is that `Stdio::capture` is now named
`stdio::piped`.

some commits in OpenBSD base have corrected a problem of stack position.
Now, we can adjust more accurately the page guard in rust.

This is leftover from #21843
If you still have `|&:| {}` closures in your code, simply remove the `&:` part.

Now that the `std::env` module has had some time to bake this commit marks most
of its APIs as `#[stable]`. Some notable APIs that are **not** stable (and still
use the same `env` feature gate) are:
* `{set,get}_exit_status` - there are still questions about whether this is the
right interface for setting/getting the exit status of a process.
* `page_size` - this may change location in the future or perhaps name as well.
This also effectively closes #22122 as the variants of `VarError` are
`#[stable]` now. (this is done intentionally)

Fixes #20978 for supported platforms (i.e. non-Android POSIX).
This uses `backtrace_pcinfo` to inspect the DWARF debug info and list the file and line pairs for given stack frame. Such pair is not unique due to the presence of inlined functions and the updated routine correctly handles this case. The code is modelled after libbacktrace's `backtrace_full` routine.
There is one known issue with this approach. Macros, when invoked, take over the current frame and shadows the file and line pair which has invoked a macro. In particular, this makes many panicking
macros a bit harder to inspect. This really is a debuginfo problem, and the backtrace routine should print them correctly with a correct debuginfo.
Some example trace:
```

- Fixed a couple of dead code warnings in std::sys::backtrace.
- Made `backtrace-debuginfo` test a no-op on non-Linux platforms.
- `backtrace-debuginfo` is no longer tested on pretty-rpass.

This patch contains a couple time fixes to make Rust compile on Bitrig again. This does not affect OpenBSD.

We were recording stability attributes applied to fields in the
compiler, and even annotating it in the libs, but the compiler didn't
actually do the checks to give errors/warnings in user crates.

Implements `Debug` for `RwLock` and `arc::Weak` in the same way it is implemented for `rc::Weak` (basically copy & paste).
The lack of this implementation prevents the automatic implementation of `Debug` for structs containing members of these types.

Instead of allocating the same ports for ipv4 and ipv6 tests, instead draw all
ports from the same pool. Some tests connect to just "localhost" on a particular
port which may accidentally be interacting with other tests as the ipv-what-ness
isn't specified with the string "localhost"
Relevant logs:
* [Deadlock of the `net::tcp::tests::listen_localhost` test][mac]
* [Failure of the `fast_rebind` test][win1]
* [Failure of `multiple_connect_interleaved_lazy_schedule_ip4`][win2]

The Path/PathBuf pair already implements the required `Borrow`/`ToOwned` traits and can be used in a `Cow` pointer, so why not?
