* Update the channel of this release
* Update the bootstrap compiler to the dev artifacts
* Fix compile for last-minute backports
|

Also remove a number of `stage0` annotations and such

Add Box::leak<'a>(Box<T>) -> &'a mut T where T: 'a
Adds:
```rust
impl<T: ?Sized> Box<T> {
pub fn leak<'a>(b: Box<T>) -> &'a mut T where T: 'a {
unsafe { &mut *Box::into_raw(b) }
}
}
```
which is useful for when you just want to put some stuff on the heap and then have a reference to it for the remainder of the program.

Improve raw Box conversions
This PR has two goals:
- Reduce use of `mem::transmute` in `Box` conversions
I understand that `mem::transmute`-ing non `#[repr(C)]` types is implementation-defined behavior. This may not matter within the reference implementation of Rust, but I believe it's important to remain consistent. For example, I noticed that `str::from_utf8_unchecked` went from using `mem::transmute` to using pointer casts.
- Make `Box` pointer conversions more straightforward regarding `Unique`

Provides a reasonable interface for Box::from_raw implementation.
Does not get around the requirement of mem::transmute for converting
back and forth between Unique and Box.
|
|
Same reasons as commit 904133e1e28b690e2bbd101b719509aa897539a0.
|
|
Seems to cause this error: "Cannot handle boxed::Box<[u8]> represented
as TyLayout".
|
|
|
|
Makes use of conversions via Unique.

This fixes headings reading "Unsafety" and "Example", they should be
"Safety" and "Examples" according to RFC 1574.

Like #43008 (f668999), but _much more aggressive_.

These show up in rustdoc so need to be correct.

This PR is an implementation of [RFC 1974] which specifies a new method of
defining a global allocator for a program. This obsoletes the old
`#![allocator]` attribute and also removes support for it.
[RFC 1974]: https://github.com/rust-lang/rfcs/pull/197
The new `#[global_allocator]` attribute solves many issues encountered with the
`#![allocator]` attribute such as composition and restrictions on the crate
graph itself. The compiler now has much more control over the ABI of the
allocator and how it's implemented, allowing much more freedom in terms of how
this feature is implemented.

Replaced by adding extra imports, adding hidden code (`# ...`), modifying
examples to be runnable (sorry Homura), specifying non-Rust code, and
converting to should_panic, no_run, or compile_fail.
Remaining "```ignore"s received an explanation why they are being ignored.

These were found by running tidy on stable versions of rust and finding
features stabilised with the wrong version numbers.

This commit updates the version number to 1.17.0 as we're not on that version of
the nightly compiler, and at the same time this updates src/stage0.txt to
bootstrap from freshly minted beta compiler and beta Cargo.

Forward more ExactSizeIterator methods and `is_empty` edits
- Forward ExactSizeIterator methods in more places, like `&mut I` and `Box<I>` iterator impls.
- Improve `VecDeque::is_empty` itself (see commit 4)
- All the collections iterators now have `len` or `is_empty` forwarded if doing so is a benefit. In the remaining cases, they already use a simple size hint (using something like a stored `usize` value), which is sufficient for the default implementation of len and is_empty.

It is an unnecessary restriction; nth neither needs self to be sized
nor needs to be exempted from the trait object.
It increases the utility of the nth method, because type specific
implementations are available through `&mut I` or through an iterator
trait object.
It is a backwards compatible change due to the special cases of the
`where Self: Sized` bound; it was already optional to include this bound
in `Iterator` implementations.

This can be confusing for newcomers, especially due to the argument
name "this".
