This commit is an implementation of [RFC 739][rfc] which adds a new `std::fs`
module to the standard library. This module provides much of the same
functionality as `std::old_io::fs` but it has many tweaked APIs as well as uses
the new `std::path` module.

This is in preparation for stabilization of the `IntoIterator` trait. All
implementations and references to `Iter` need to be renamed to `IntoIter`.

- add namespace
- add function parens
|
|
Update reference.md:
- derive() no longer supports Zero trait
- derive() now supports Copy trait

Fixes #21915
|
|
New functions, `slice::from_raw_parts` and `slice::from_raw_parts_mut`,
are added to implement the lifetime convention as agreed in rust-lang/rfcs#556.
The functions `slice::from_raw_buf` and `slice::from_raw_mut_buf` are
left deprecated for the time being.
Holding back on changing the signature of `std::ffi::c_str_to_bytes` as consensus in rust-lang/rfcs#592 is building to replace it with a composition of other functions.
Contribution to #21923.

This is 99% burning ints to the ground, but I also got rid of useless annotations or made code more \"idiomatic\" as I went along. Mostly changes in tests.

This was particularly helpful in the time just after OIBIT's
implementation to make sure things that were supposed to be Copy
continued to be, but it's now creates a lot of noise for types that
intentionally don't want to be Copy.

This also removes two erroneous re-exports of the Entry variants, and so is incidentally a [breaking-change], though presumably no one should have been using those.

The spelling corrections were made in both documentation comments and
regular comments.

- add `_SC_GETPW_R_SIZE_MAX` constant
- declare `struct passwd`
- convert `load_self` to `current_exe`
Note: OpenBSD don't provide system function to return a valuable Path
for `env::current_exe`. The implementation is currently based on the
value of `argv[0]`, which couldn't be used when executable is called via
PATH.

These were forgotten reexports from #21718
Closes #21929

`{` and `}` aren’t valid characters on ARM, so this makes Unicode characters render as, e.g., `$u38d$` instead of `$u{38d}`.
This also fixes a small bug where `)` (**r**ight **p**arenthesis) and `*` (**r**aw **p**ointer) would both mangle to `$RP$`, making `)` show up as `*` in backtraces.

Use [`rand`](https://crates.io/crates/rand) and [`derive_rand`](https://crates.io/crates/derive_rand) from crates.io.

Currently, if a `#![staged_api]` crate contains an exported item without a stability marker (or inherited stability),
the item is useless.
This change introduces a check to ensure that all exported items have a defined stability.
it also introduces the `unmarked_api` feature, which lets users import unmarked features. While this PR should in theory forbid these from existing,
in practice we can't be so sure; so this lets users bypass this check instead of having to wait for the library and/or compiler to be fixed (since otherwise this is a hard error).

This commit is an implementation of [RFC 576][rfc] which adds back the `std::io`
module to the standard library. No functionality in `std::old_io` has been
deprecated just yet, and the new `std::io` module is behind the same `io`
feature gate.
[rfc]: https://github.com/rust-lang/rfcs/pull/576
A good bit of functionality was copied over from `std::old_io`, but many tweaks
were required for the new method signatures. Behavior such as precisely when
buffered objects call to the underlying object may have been tweaked slightly in
the transition. All implementations were audited to use composition wherever
possible. For example the custom `pos` and `cap` cursors in `BufReader` were
removed in favor of just using `Cursor<Vec<u8>>`.
A few liberties were taken during this implementation which were not explicitly
spelled out in the RFC:
* The old `LineBufferedWriter` is now named `LineWriter`
* The internal representation of `Error` now favors OS error codes (a
0-allocation path) and contains a `Box` for extra semantic data.
* The io prelude currently reexports `Seek` as `NewSeek` to prevent conflicts
with the real prelude reexport of `old_io::Seek`
* The `chars` method was moved from `BufReadExt` to `ReadExt`.
* The `chars` iterator returns a custom error with a variant that explains that
the data was not valid UTF-8.
