A number of functions/methods have been moved or renamed to align
better with rust standard conventions.
std::reflect::MovePtrAdaptor => MovePtrAdaptor::new
debug::reflect::MovePtrAdaptor => MovePtrAdaptor::new
std::repr::ReprVisitor => ReprVisitor::new
debug::repr::ReprVisitor => ReprVisitor::new
rustuv::homing::HomingIO.go_to_IO_home => go_to_io_home

We already have into_string(), but it was implemented in terms of
into_owned(). Flip it around and deprecate into_owned().
Remove a few spurious calls to .into_owned() that existed in libregex
and librustdoc.
This commit shuffles around some of the `rand` code, along with some
reorganization. The new state of the world is as follows:
* The librand crate now only depends on libcore. This interface is experimental.
* The standard library has a new module, `std::rand`. This interface will
eventually become stable.
Unfortunately, this entailed more of a breaking change than just shuffling some
names around. The following breaking changes were made to the rand library:
* Rng::gen_vec() was removed. This has been replaced with Rng::gen_iter() which
will return an infinite stream of random values. Previous behavior can be
regained with `rng.gen_iter().take(n).collect()`
* Rng::gen_ascii_str() was removed. This has been replaced with
Rng::gen_ascii_chars() which will return an infinite stream of random ascii
characters. Similarly to gen_iter(), previous behavior can be emulated with
`rng.gen_ascii_chars().take(n).collect()`
* {IsaacRng, Isaac64Rng, XorShiftRng}::new() have all been removed. These all
relied on being able to use an OSRng for seeding, but this is no longer
available in librand (where these types are defined). To retain the same
functionality, these types now implement the `Rand` trait so they can be
generated with a random seed from another random number generator. This allows
the stdlib to use an OSRng to create seeded instances of these RNGs.
* Rand implementations for `Box<T>` and `@T` were removed. These seemed to be
pretty rare in the codebase, and it allows for librand to not depend on
liballoc. Additionally, other pointer types like Rc<T> and Arc<T> were not
supported. If this is undesirable, librand can depend on liballoc and regain
these implementations.
* The WeightedChoice structure is no longer built with a `Vec<Weighted<T>>`,
but rather a `&mut [Weighted<T>]`. This means that the WeightedChoice
structure now has a lifetime associated with it.
* The `sample` method on `Rng` has been moved to a top-level function in the
`rand` module due to its dependence on `Vec`.

This commit moves reflection (as well as the {:?} format modifier) to a new
libdebug crate, all of which is marked experimental.
This is a breaking change because it now requires the debug crate to be
explicitly linked if the :? format qualifier is used. This means that any code
using this feature will have to add `extern crate debug;` to the top of the
crate. Any code relying on reflection will also need to do this.

With the test runner using ::std::os::args(), and std::std::os now being
a re-export of realstd::os, there's no more need for realstd stuff
mucking up rt::args.
Remove the one test of os::args(), as it's not very useful and it won't
work anymore now that rt::args doesn't use realstd.
As part of the libstd facade (cc #13851), rustdoc is taught to inline documentation across crate boundaries through the usage of a `pub use` statement. This is done to allow libstd to maintain the facade that it is a standalone library with a defined public interface (allowing us to shuffle around what's underneath it).

Paper over privacy issues with Deref by changing field names.
Types that implement Deref can cause weird error messages due to their
private fields conflicting with a field of the type they deref to, e.g.,
previously
struct Foo { x: int }
let a: Arc<Foo> = ...;
println!("{}", a.x);
would complain the the `x` field of `Arc` was private (since Arc has a
private field called `x`) rather than just ignoring it.
This patch doesn't fix that issue, but does mean one would have to write
`a._ptr` to hit the same error message, which seems far less
common. (This patch `_`-prefixes all private fields of
`Deref`-implementing types.)

Some functions implemented for the Ascii struct have the same functionality as other functions implemented for the normal chars. For consistency, I think they should have the same name, so I renamed the functions in Ascii to match the names in the Char trait.
* Renamed `to_lower` to `to_lowercase`
* Renamed `to_upper` to `to_uppercase`
* Renamed `is_alpha` to `is_alphabetic`
* Renamed `is_alnum` to `is_alphanumeric`
* Renamed `is_lower` to `is_lowercase`
* Renamed `is_upper` to `is_uppercase`

On some systems (iOS for example) mutex is represented by opaque data structure which doesn't play well with simple data copy. Therefore mutex should be initialized from magic static value and filled by OS only when it landed RC.
Initially written for iOS but since landing iOS support might require quite a lot of time I think it is better to split parts which aren't directly related to iOS and merge them in

The span on a inner doc-comment would point to the next token, e.g. the span for the `a` line points to the `b` line, and the span of `b` points to the `fn`.
```rust

fn bar() {}

One of the long-term goals of the libstd facade is to move the collections
library underneath the standard library. This would imply that libcollections
today would invert its dependency with libstd.
One of the primary blockers for doing this is the HashMap collection. Of its two
major dependencies, hashing and randomness, this commit is the first step in
dealing with hashing.
When moving the hash module beneath libstd, it must break its primary dependence
on the io::Writer trait (used as the hashing state). The proposed strategy for
breaking this dependence is taking a similar path as core::fmt, which is to have
the hash module define its own "writer trait". This trait would be similar to
std::io::Writer, except that it would not return errors and it would have fewer
convenience methods.
The Hash trait today has its type parameter behind a feature gate (default type
parameters), so this pending change will likely break no code which hasn't opted
in to the feature gate. The SipState struct will lose its implementation of
io::Writer, but it will regain similar methods for dealing with writing data.
This change specifically prepares for the hash migration by modifying
deriving(Hash) to use the std:#️⃣:Writer bound instead of the std::io::Writer
bound. This bound is currently wired to std::io::Writer, but after a snapshot it
will have no need to be wired to the io writer trait.
