* 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)?;
| ------------------------------------
| |
| the trait `std::ops::Carrier` is not implemented for `()`
| in this macro invocation
|
= 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.

Improve the docs for the write and writeln macros
This change reduces duplication by linking the documentation for
`writeln!` to `write!`. It also restructures the `write!` documentation
to read in a more logical manner (I hope; feedback would be welcome).

Implement all PartialOrd methods for Reverse
When making a forwarding wrapper we must in general forward all methods,
so that we use the type's own `lt` for example instead of the default.
Example important case: f32's partial_cmp does several operations but
its lt is a primitive.
Follow up on #40720
adding debug in consume_body function
When in debug_assertions=true mode, the function consume_body lacks some debug output, which makes it harder to follow the control flow. This commit adds this needed debug.
Add example to std::process::abort
This is a first step in order to complete this issue: https://github.com/rust-lang/rust/issues/29370
I submitted this PR with the help of @steveklabnik More info here: https://github.com/rust-lang/rust/issues/29370#issuecomment-290089330
It's my first PR on Rust, I'm learning how to contribute: Should I ping someone? I will post another PR with a more complicated example soon, I prefer send it separately (cause maybe I made some mistakes).
Implement AsRawFd/IntoRawFd for RawFd
This is useful to build os abstraction like the nix crate does.
It allows to define functions, which accepts generic arguments
of data structures convertible to RawFd, including RawFd itself.
For example:
```
fn write<FD: AsRawFd>(fd: FD, buf: &[u8]) -> Result<usize>
write(file, buf);
```
instead of:
```
fn write(fd: RawFd, buf: &[u8]) -> Result<usize>
write(file.as_raw_fd(), buf);
```
