All of the enum components had a redundant 'Type' specifier: TypeSymlink, TypeDirectory, TypeFile. This change removes them, replacing them with a namespace: FileType::Symlink, FileType::Directory, and FileType::RegularFile.
RegularFile is used instead of just File, as File by itself could be mistakenly thought of as referring to the struct.

This patch merges the `libsync` crate into `libstd`, undoing part of the
facade. This is in preparation for ultimately merging `librustrt`, as
well as the upcoming rewrite of `sync`.
Because this removes the `libsync` crate, it is a:

However, all uses of `libsync` should be able to reroute through
`std::sync` and `std::comm` instead.
Just like we do with AsSlice
This comes in handy when dealing with iterator-centric APIs (`IntoIterator`!) and you want to receive an `Iterator<S> where S: Str` argument. Without this PR, e.g. you can't receive `&["a", "b"].iter()` instead you'll have to type `&["a", "b"].iter().map(|&x| x)` (A similar thing happens with `&[String]`).

This commit removes the `std::local_data` module in favor of a new `std::thread_local`
module providing thread local storage. The module provides two variants of TLS:
one which owns its contents and one which is based on scoped references. Each
implementation has pros and cons listed in the documentation.
Both flavors have accessors through a function called `with` which yield a
reference to a closure provided. Both flavors also panic if a reference cannot
be yielded and provide a function to test whether an access would panic or not.
This is an implementation of [RFC 461][rfc] and full details can be found in
that RFC.
This is a breaking change due to the removal of the `std::local_data` module.
All users can migrate to the new tls system like so:
thread_local!(static FOO: Rc<RefCell<Option<T>>> = Rc::new(RefCell::new(None)))
The old `local_data` module inherently contained the `Rc<RefCell<Option<T>>>` as
an implementation detail which must now be explicitly stated by users.

Whilst browsing the source for BinaryHeap, I saw a FIXME for implementing into_iter. I think, since the BinaryHeap is represented internally using just a Vec, just calling into_iter() on the BinaryHeap's data should be sufficient to do what we want here. If this actually isn't the right approach (e.g., I should write a struct MoveItems and appropriate implementation for BinaryHeap instead), let me know and I'll happily rework this.
Both of the tests that I have added pass. This is my first contribution to Rust, so please let me know any ways I can improve this PR!

A single impl supports all of `[T]`, `Vec<T>` and `CVec<T>`.
Once `Iterable` is implemented, we will prefer it to `SlicePrelude`.
But the `with_capacity()` part might become tricky.
This change applies the conventions to unwrap listed in [RFC 430][rfc] to rename
non-failing `unwrap` methods to `into_inner`. This is a breaking change, but all
`unwrap` methods are retained as `#[deprecated]` for the near future. To update
code rename `unwrap` method calls to `into_inner`.

This PR:
- makes rustdoc colour trait methods like other functions in search results;
- makes rustdoc display `extern crate` statements with the new `as` syntax instead of the old `=` syntax;
- changes rustdoc to list constants and statics in a way that is more similar to functions and modules and show their full definition and documentation on their own page, fixing #19046:

I would appreciate any guidance on how to write a test for this. I saw some examples in `test/pretty`, but there are different ways to test... With or without `.pp` files, with a `pp-exact` comment, etc.
This breaks code like
```
let t = (42i, 42i);
... t.0::<int> ...;
```
Change this code to not contain an unused type parameter. For example:
```
let t = (42i, 42i);
... t.0 ...;
```

Catch a missed triple-slash in the docs for `std::os::args()`. Passes `make check`. (I've also eyeballed the rest of `libstd` with the aid of some funky regexes and haven't found anything similar.)
This is an initial API stabilization pass for `std::ascii`. Aside from
some renaming to match conversion conventions, and deprecations in favor
of using iterators directly, almost nothing is changed here. However,
the static case conversion tables that were previously public are now private.
The stabilization of the (rather large!) set of extension traits is left
to a follow-up pass, because we hope to land some more general machinery
that will provide the same functionality without custom traits.

These functions allow you to see how many weak and strong references
there are to an `Arc`, `Rc`, or an `rc::Weak`. Due to the design of
`Arc` it is not possible to get the number of weak references of an
arbitrary `arc::Weak`. Look in `arc.rs` for a more in-depth explanation.
On `arc::Arc` and `arc::Weak` these operations are wait-free and atomic.
This sort of information is useful for creating dynamically cleared caches for use in OS development, for example holding pages of files in memory until the address space is needed for something else.
This is a collection of misc issues I've run into while adding bindir & libdir support that aren't really bindir & libdir specific.
While I continue to fiddle with bindir and libdir bugs, I figured these might be useful for others to have merged.
The reason given didn't make any sense when I read it when reading through the docs. I think this is more clear. Please let me know it is also more correct.
