Rename io::timer::sleep, Timer::sleep, Timer::oneshot,
Timer::periodic, to sleep_ms, oneshot_ms, periodic_ms. These functions
all take an integer and interpret it as milliseconds.
Replacement functions will be added that take Duration.

rust.md: Explicitly point out how special `'static` is.
Drive-by: fix description of `&content` to point out that `&'f type` is (as of today) only for type expressions.
This fixes borrow checking for closures. Code like this will break:
struct Foo {
x: int,
}
pub fn main() {
let mut this = &mut Foo {
x: 1,
};
let r = || {
let p = &this.x;
&mut this.x;
};
r()
}
Change this code to not take multiple mutable references to the same value. For
example:
struct Foo {
x: int,
}
pub fn main() {
let mut this = &mut Foo {
x: 1,
};
let r = || {
&mut this.x;
};
r()
}

`for` loop heads.
This breaks code like:
let x = Some(box 1i);
for &a in x.iter() {
}
Change this code to obey the borrow checking rules. For example:
let x = Some(box 1i);
for &ref a in x.iter() {
}

* The caller should be responsible for cleaning up file descriptors
* If a caller safely creates a file descriptor (via
native::io::file::open) the returned structure (FileDesc) will try to
clean up the file, failing in the process and writing error messages
to the screen.
* This should not happen as the caller has no public interface for
telling the FileDesc structure to NOT free the underlying fd.
* Alternatively, if another file is opened under the same fd held by
the FileDesc structure returned by native::io::file::open, it will
close the wrong file upon destruction.
This code produces an ICE:
```rust
#![crate_type = "rlib"]
fn main() {
if true { return }
// remaining code is unreachable
match () {
() => { static MAGIC: uint = 0; }
}
}
```
([playpen](http://is.gd/iwOISB))
The error is "encode_symbol: id not found 18", where 18 is the `NodeId` of the declaration of `MAGIC`. The problem is that `rustc` tries to emit metadata for `MAGIC`, but some of the information is missing because `MAGIC` never gets translated by `trans_item` - the entire body of the `match` gets skipped because the `match` itself is unreachable.
This branch simplifies the handling of inner items by always processing them using the `trans_item` visitor, instead of sometimes using the visitor and sometimes waiting until `trans_stmt` encounters the item. This fixes the ICE by making the translation of the item no longer depend on the declaration being reachable code. This branch also reverts #16059 and #16359, since the new change to item translation fixes the same problems as those but is simpler.

Previously the stability lint considered cross-crate items only. That's appropriate for unstable and experimental levels, but not for deprecation.
In addition to changing the lint, this PR takes care of the fallout: a number of deprecated items that were being used throughout libstd.

There was a bug in both libnative and libuv which prevented child processes from
being spawned correctly on windows when one of the arguments was an empty
string. The libuv bug has since been fixed upstream, and the libnative bug was
fixed as part of this commit.
When updating libuv, this also includes a fix for #15149.

- Moved examples for permutations and next into trait definition as
comments on pull request #16244.
- Fixed (hopefully) issue with erronious commit of changes to src/llvm.
Since https://github.com/rust-lang/rust/pull/16380 didn't get pulled in yet, I added it in here too.
This covers the very, very, very basics of vectors. I wanted to have a section that mentioned them, but I'm
unsure what else I should cover. So I just did the absolute simplest things. Feedback very welcome.
Previously we would accept an empty log level without an equals sign, but not with one. This addresses that minor nit. E.g., `RUST_LOG=rustc::middle::trans=` will work the same as `RUST_LOG=rustc::middle::trans`.

The fail macro defines some function/static items internally, which got
a dead_code warning when `fail!()` is used inside a dead function. This
is ugly and unnecessarily reveals implementation details, so the
warnings can be squashed.
Fixes#16192.
