[Previously](e5da6a71a6),
the `Any` trait was split into a private portion and an (empty) public
portion, in order to hide the implementation strategy used for
downcasting. However, the [new
rules](e9ad12c0ca)
for privacy forbid `AnyPrivate` from actually being private.
This patch thus reverts the introduction of `AnyPrivate`.
Although this is unlikely to break any real code, it removes a public
trait and is therefore a:
[breaking-change]
This bound is already implicit through the AnyPrivate trait,
but since it is not explicit, you still have to write Box<Any + 'static>,
even though Any can only be 'static.
Introducing the 'static bound here makes this bound explicit, making
Box<Any> legal.

This commit is another in the series of vector slice API
stabilization. The focus here is the *mutable* slice API.
Largely, this API inherits the stability attributes [previously
assigned](https://github.com/rust-lang/rust/pull/16332) to the analogous
methods on immutable slides. It also adds comments to a few `unstable`
attributes that were previously missing them.
In addition, the commit adds several `_mut` variants of APIs that were
missing:
- `init_mut`
- `head_mut`
- `tail_mut`
- `splitn_mut`
- `rsplitn_mut`
Some of the unsafe APIs -- `unsafe_set`, `init_elem`, and `copy_memory`
-- were deprecated in favor of working through `as_mut_ptr`, to simplify
the API surface.
Due to deprecations, this is a:
[breaking-change]
Moves the vast majority of builtin bound checking out of type contents and into the trait system.
This is a preliminary step for a lot of follow-on work:
- opt-in builtin types, obviously
- generalized where clauses, because TypeContents has this notion that a type parameter has a single set of builtin kinds, but with where clauses it depends on context
- generalized coherence, because this adds support for recursive trait selection
Unfortunately I wasn't able to completely remove Type Contents from the front-end checking in this PR. It's still used by EUV to decide what gets moved and what doesn't.

Intended to prevent each user to write his own partial_min/max, possibly differing in slight details. @sfackler encouraged to PR this on IRC.
(Let's hope this works... First PR.)
OrdIterator: the doc says that values must implement `PartialOrd`, while the implementation is only for `Ord` values. It looks like this initially got out of sync in 4e1c215. Removed the doc sentence entirely since it seems redundant.
MultiplicativeIterator: Fixed weird sentence.
