Added links to types in from_utf8 description
References #29375. Link to types mentioned in the documentation for `from_utf8` (`str`, `&[u8`], etc). Paragraphs were reformatted to keep any one line from being excessively long, but are otherwise unchanged.
Added links to from_utf8 methods in Utf8Error
Referencing #29375. Linked the `from_utf8` methods for both `String` and `str` in the description. Also linked the `u8` to its documentation
Add links and some examples to std::sync::mpsc docs
Addresses part of #29377
r? @steveklabnik
I took a stab at adding links to the `std::sync::mpsc` docs, and I also wrote a few examples.
Edit: Whoops, typed in `?r` instead of `r?`.
rustc: Stabilize the `#![windows_subsystem]` attribute
This commit stabilizes the `#![windows_subsystem]` attribute which is a
conservative exposure of the `/SUBSYSTEM` linker flag on Widnows platforms. This
is useful for creating applications as well as console programs.
Closes#37499
Point at last valid token on failed `expect_one_of`
```rust
error: expected one of `.`, `;`, `?`, `}`, or an operator, found `)`
--> $DIR/token-error-correct-3.rs:29:9
|
25 | foo()
| - expected one of `.`, `;`, `?`, `}`, or an operator after this
...
29 | } else {
| ^ unexpected token
```
Fix#32540.
travis: Split all dist builders in two
Previously we would use one builder on Travis to produce two sets of host
compilers for two different targets. Unfortunately though we've recently
increased how much we're building for each target so this is starting to take
unnecessarily long (#40804). This commit splits the dist builders in two by
ensuring that we only dist one target on each builder, which should take a much
shorter amount of time. This should also unblock other work such as landing the
RLS (#40584).

* Change `utf8` variable names to `non_ascii` to be more clear, since
ASCII and UTF-8 are compatible.
* Fix `EscapeDefault` struct description to follow the typical iterator
method format with a link to the generating function.
* Add more `escape_default` examples to cover every case mentioned in
the function description itself.
travis: Compile OSX releases with Xcode 7
Unfortunately what we're using right now, Xcode 8.2, cannot compile LLVM for OSX
10.7. We've done this historically and Gecko would like to maintain this
compabitiliby. This commit moves our release builders for OSX to using Xcode 7
which can compile LLVM for 10.7.
The builders running tests continue to use Xcode 8.2, however, because the LLDB
version with Xcode 7, 350, is blacklisted in running our LLDB tests. To continue
running LLDB tests we'll stick with Xcode 8.2.
Test sort algorithms using a random cmp function
This ensures that sorting using a broken comparison function doesn't panic nor fail in some other way (especially not segfault).

Add helpful hint in io docs about how ? is not allowed in main()
This is my effort to help alleviate the confusion caused by the error message:
```rust
error[E0277]: the trait bound `(): std::ops::Carrier` is not satisfied
--> hello_world.rs:72:5
|
72 | io::stdin().read_line(&mut d_input)?;
| ------------------------------------

= note: required by `std::ops::Carrier::from_error`
error: aborting due to previous error
```
This has been discussed at length in https://github.com/rust-lang/rust/issues/35946, but I figured it would be helpful to mention in the docs.
Reading user input is one of the first things beginners will look up in the docs, so my thinking was they'd see this warning here and not have to deal with the [tricky error message](https://blog.rust-lang.org/2017/03/02/lang-ergonomics.html).
If you think this isn't the right place to put this in the docs, that's understandable, I'm open to suggestions for putting it elsewhere or removing it entirely.
