std: remove a workaround for privacy limitations
`std::thread::Thread` implements a non-exported `NewThread` trait to allow for internal-only use of `Thread::new`. Nowadays we have `pub(crate)`, which accomplishes the same thing but much more idiomatically.
Rustdoc handles this correctly (I checked and I didn't see `Thread::new` on the rustdoc entry for `Thread` with this change), and the stage1 `rustc` emits the correct error still (I'm assuming that the stage1 compiler uses my `libstd`?):
```
$ ./build/x86_64-apple-darwin/stage1/bin/rustc test.rs
error: method `new` is private
--> test.rs:4:18

4 | let thread = thread::Thread::new(None);

error: aborting due to previous error
```

Add doc examples for `OsStr`, `OsString`.

Update usages of 'OSX' (and other old names) to 'macOS'.
As of last year with version 'Sierra', the Mac operating system is now
called 'macOS'.

Remove function invokation parens from documentation links.
This was never established as a convention we should follow in the 'More
API Documentation Conventions' RFC:

Leftovers from #39594; From<Box> impls
These are a few more impls that follow the same reasoning as those from #39594.
What's included:
* `From<Box<str>> for String`
* `From<Box<[T]>> for Vec<T>`
* `From<Box<CStr>> for CString`
* `From<Box<OsStr>> for OsString`
* `From<Box<Path>> for PathBuf`
* `Into<Box<str>> for String`
* `Into<Box<[T]>> for Vec<T>`
* `Into<Box<CStr>> for CString`
* `Into<Box<OsStr>> for OsString`
* `Into<Box<Path>> for PathBuf`
* `<Box<CStr>>::into_c_string`
* `<Box<OsStr>>::into_os_string`
* `<Box<Path>>::into_path_buf`
* Tracking issue for latter three methods + three from previous PR.
Currently, the opposite direction isn't doable with `From` (only `Into`) because of the separation between `liballoc` and `libcollections`. I'm holding off on those for a later PR.

OsString::shrink_to_fit.
Considering how the other capacity-related methods are there, I found it odd that this one wasn't included.
Will create a tracking issue once I get an OK on this.

Distinguish the ways `CStr::from_bytes_with_nul` can fail

This change introduces a Dockerfile and script which builds a complete
Fuchsia toolchain which can be used to build Rust distribution for
Fuchsia. We only support cross-compiling at the moment, hence only
setting the target.

clarify docs for Args and ArgsOs
The args() and args_os() docs include a line about how the first element
is usually the program name. Include that line in the struct docs too.
|

Reduce size overhead of adaptative hashmap
Exposes a boolean flag in RawTable and use it instead of a bool field in HashMap.
Taking a bit from capacity or length would make overflow handling tricky.
Fixes: #40042

these belong to a previous iteration of the sanitizer implementation

Reduce std_unicode’s public API
* Only keep one copy of the `UTF8_CHAR_WIDTH` table instead of one of each of libcore and libstd_unicode.
* Move the `utf8_char_width` function to `core::str` under the `str_internals` unstable feature.
* Remove `std_unicode::str::is_utf16`. It was only accessible through the `#[unstable]` crate std_unicode. It has never been used in the compiler or standard library since 47e7a05 added it in 2012 “for OS API interop”. It can be replaced with a one-liner:
```rust
fn is_utf16(slice: &[u16]) -> bool {
std::char::decode_utf16(s).all(|r| r.is_ok())
}
```

std::process for fuchsia: updated to latest liblaunchpad
Our liblaunchpad changed a bit and so fuchsia's std::process impl needs to change a bit.

added Error and Display impl for std::ffi::FromBytesWithNulError
Fixes #39925.
This is my first PR, so I wasn't quite sure about the stability annotation.

Example for how to provide stdin using std::process::Command
Spawning a child process and writing to its stdin is a bit tricky due to
`as_mut` and having to use a limited borrow. An example for this might
help newer users.

Improve backtrace formating while panicking.
Fixes #37783.
Done:
- Fix alignment of file paths for better readability
- `RUST_BACKTRACE=full` prints all the informations (current behaviour)
- `RUST_BACKTRACE=(short|yes)` is the default and does:
- Skip irrelevant frames at the beginning and the end
- Remove function address
- Remove the current directory from the absolute paths
- Remove `::hfabe6541873` at the end of the symbols
- `RUST_BACKTRACE=(0|no)` disables the backtrace.
- `RUST_BACKTRACE=<everything else>` is equivalent to `short` for
backward compatibility.
- doc
- More uniform printing across platforms.
Removed, TODO in a new PR:
- Remove path prefix for libraries and libstd
Example of short backtrace:
```rust
fn fail() {
panic!();
}
fn main() {
let closure = || fail();
closure();
}
```
Short:
```
thread 'main' panicked at 'explicit panic', t.rs:2
Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
stack backtrace:
0: t::fail
at ./t.rs:2
1: t::main::{{closure}}
at ./t.rs:6
2: t::main
at ./t.rs:7
```
Full:
```
thread 'main' panicked at 'This function never returns!', t.rs:2
