For example, this renames `GroupRWX` to `GROUP_RWX`, and deprecates the old
name. Code using these statics should be updated accordingly.

This commit removes the `iotest!` macro from `std::io`. The macro was
primarily used to ensure that all io-related tests were run on both
libnative and libgreen/librustuv. However, now that the librustuv stack
is being removed, the macro is no longer needed.
See the [runtime removal
RFC](https://github.com/rust-lang/rfcs/pull/230) for more context.

type they provide an implementation for.
This breaks code like:
mod foo {
struct Foo { ... }
}
impl foo::Foo {
...
}
Change this code to:
mod foo {
struct Foo { ... }
impl Foo {
...
}
}
Additionally, if you used the I/O path extension methods `stat`,
`lstat`, `exists`, `is_file`, or `is_dir`, note that these methods have
been moved to the the `std::io::fs::PathExtensions` trait. This breaks
code like:
fn is_it_there() -> bool {
Path::new("/foo/bar/baz").exists()
}
Change this code to:
use std::io::fs::PathExtensions;
fn is_it_there() -> bool {
Path::new("/foo/bar/baz").exists()
}

ImmutableEqVector -> ImmutableEqSlice
ImmutableOrdVector -> ImmutableOrdSlice
MutableVector -> MutableSlice
MutableVectorAllocating -> MutableSliceAllocating
MutableCloneableVector -> MutableCloneableSlice
MutableOrdVector -> MutableOrdSlice
These are all in the prelude so most code will not break.

std: rename MemWriter to SeekableMemWriter, add seekless MemWriter
Not all users of MemWriter need to seek, but having MemWriter seekable adds between 3-29% in overhead in certain circumstances. This fixes that performance gap by making a non-seekable MemWriter, and creating a new SeekableMemWriter for those circumstances when that functionality is actually needed.

Currently when a read-only file has unlink() invoked on it on windows, the call
will fail. On unix, however, the call will succeed. In order to have a more
consistent behavior across platforms, this error is recognized on windows and
the file is changed to read-write before removal is attempted.

This PR is the outcome of the library stabilization meeting for the
`liballoc::owned` and `libcore::cell` modules.
Aside from the stability attributes, there are a few breaking changes:
* The `owned` modules is now named `boxed`, to better represent its
contents. (`box` was unavailable, since it's a keyword.) This will
help avoid the misconception that `Box` plays a special role wrt
ownership.
* The `AnyOwnExt` extension trait is renamed to `BoxAny`, and its `move`
method is renamed to `downcast`, in both cases to improve clarity.
* The recently-added `AnySendOwnExt` extension trait is removed; it was
not being used and is unnecessary.

This breaks a fair amount of code. The typical patterns are:
* `for _ in range(0, 10)`: change to `for _ in range(0u, 10)`;
* `println!("{}", 3)`: change to `println!("{}", 3i)`;
* `[1, 2, 3].len()`: change to `[1i, 2, 3].len()`.

Replace its usage with byte string literals, except in `bytes!()` tests.
Also add a new snapshot, to be able to use the new b"foo" syntax.
The src/etc/2014-06-rewrite-bytes-macros.py script automatically
rewrites `bytes!()` invocations into byte string literals.
Pass it filenames as arguments to generate a diff that you can inspect,
or `--apply` followed by filenames to apply the changes in place.
Diffs can be piped into `tip` or `pygmentize -l diff` for coloring.

The `FileStat` struct contained a `path` field, which was filled by the
`stat` and `lstat` function. Since this field isn't in fact returned by
the operating system (it was copied from the paths passed to the
functions) it was removed, as in the `fstat` case we aren't working with
a `Path`, but directly with a fd.
If your code used the `path` field of `FileStat` you will now have to
manually store the path passed to `stat` along with the returned struct.

These implementations must live in libstd right now because the fmt module has

Just to be clear, there are new extension traits, but they are not necessary
once the std::fmt module has migrated to libcore, which is a planned migration
in the future.

Note that `~self` still remains, since I forgot to add support for

How to update your code:

* Instead of `~TYPE`, you should write `Box<Type>`.

This patch changes `std::io::FilePermissions` from an exposed `u32`
representation to a typesafe representation (that only allows valid
flag combinations) using the `std::bitflags`, thus ensuring a greater
degree of safety on the Rust side.
Despite the change to the type, most code should continue to work
as-is, sincde the new type provides bit operations in the style of C
flags. To get at the underlying integer representation, use the `bits`
method; to (unsafely) convert to `FilePermissions`, use
`FilePermissions::from_bits`.
Closes #6085.

Previously, windows was using the CREATE_NEW flag which fails if the file
