b796c1d614 Updated unicode escape documentation to match current implementation.
Unicode escapes were changed in [this
RFC](28aeb3c391/text/0446-es6-unicode-escapes.md)
to use the ES6 \u{00FFFF} syntax with a variable number of digits from
1-6, eliminating the need for two different syntaxes for unicode
literals.

e8489d3cc7 Auto merge of #21792 - nikomatsakis:orphan-ordered-first, r=aturon
Update the coherence rules to "covered first" -- the first type parameter to contain either a local type or a type parameter must contain only covered type parameters.

1935bbd913 Make use of a binary operator's RHS type for LHS inference
For "symmetric" binary operators, meaning the types of two side must be
equal, if the type of LHS doesn't know yet but RHS does, use that as an
hint to infer LHS' type.

ac1a03d742 rollup merge of #21718: alexcrichton/stabilize-from-str
This commits adds an associated type to the `FromStr` trait representing an
error payload for parses which do not succeed. The previous return value,
`Option<Self>` did not allow for this form of payload. After the associated type
was added, the following attributes were applied:

* `FromStr` is now stable
* `FromStr::Err` is now stable
* `FromStr::from_str` is now stable
* `StrExt::parse` is now stable
* `FromStr for bool` is now stable
* `FromStr for $float` is now stable
* `FromStr for $integral` is now stable
* Errors returned from stable `FromStr` implementations are stable
* Errors implement `Display` and `Error` (both impl blocks being `#[stable]`)

I really am not sure I'm doing this right, so here goes nothing...

Also testing this isn't easy. I don't have any other *nix boxes besides a Linux one.

Test code:

```rust
use std::thread;
use std::io::timer::sleep;
use std::time::duration::Duration;

fn make_thread<'a>(i: i64) -> thread::JoinGuard<'a, ()>
{
	thread::Builder::new().name(format!("MyThread{}", i).to_string()).scoped(move ||
	{
		println!("Start: {}", i);
		sleep(Duration::seconds(i));
		println!("End: {}", i);
	})
}

fn main()
{
	let mut guards = vec![make_thread(3)];

	for i in 4i64..16
	{
		guards.push(make_thread(i));
	}
}
```

GDB output on my machine:

b446c5b679 rollup merge of #21495: richo/unexported-unmangled-lint
The usecase is that functions made visible to systems outside of the
rust ecosystem require the symbol to be visible.

This adds a lint for functions that are not exported, but also not mangled.

It has some gotchas:

[ ]: There is fallout in core that needs taking care of
[ ]: I'm not convinced the error message is correct
[ ]: It has no tests

~~However, there's an underlying issue which I'd like feedback on- which is that my belief that that non-pub functions would not have their symbols exported, however that seems not to be the case in the first case that this lint turned up in rustc (`rust_fail`), which intuition suggests has been working.~~

This seems to be a separate bug in rust, wherein the symbols are exported in binaries, but not in rlibs or dylibs. This lint would catch that case.

341e858bd8 rollup merge of #20790: japaric/for-loops
As per [RFC #235][rfc], you can now do:

[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0235-collections-conventions.md#intoiterator-and-iterable

``` rust
let mut v = vec![1];

// iterate over immutable references
for x in &v {
    assert_eq!(x, &1);
}

// iterate over mutable references
for x in &mut v {
    assert_eq!(x, &mut 1);
}

// iterate over values, this consumes `v`
for x in v {
    assert_eq!(x, 1);
}
```

[breaking-change]s

For loops now "consume" (move) the iterator, this breaks iterating over mutable references to iterators, and also breaks multiple iterations over the same iterator:

``` rust
fn foo(mut it: &mut Iter) {  // `Iter` implements `Iterator`
    for x in it { .. }  //~ error: `&mut Iter` doesn't implement Iterator
}

fn bar() {
    for x in it { .. }  //~ note: `it` moved here
    for x in it { .. }  //~ error: `it` has been moved
}
```

Both cases can be fixed using the `by_ref()` adapter to create an iterator from the mutable reference:

``` rust
fn foo(mut it: &mut Iter) {
    for x in it.by_ref() { .. }
}

fn bar() {
    for x in it.by_ref() { .. }
    for x in it { .. }
}
```

This PR also makes iterator non-implicitly copyable, as this was source of subtle bugs in the libraries. You can still use `clone()` to explictly copy the iterator.

Finally, since the for loops are implemented in the frontend and use global paths to `IntoIterator`, `Iterator` and `Option` variants, users of the `core` crate will have to use add an `std` module to the root of their crate to be able to use for loops:

``` rust
#![no_std]

extern crate core;

fn main() {
    for x in 0..10 {}
}

#[doc(hidden)]
mod std {
    // these imports are needed to use for-loops
    pub use core::iter;
    pub use core::option;
}
```
