Throughout the docs, "failure" was replaced with "panics" if it means a
task panic. Otherwise, it remained as is, or changed to "errors" to
clearly differentiate it from a task panic.

These modules will house the code that used to be part of the runtime system
in libnative. The `sys_common` module contains a few low-level but
cross-platform details. The `sys` module is set up using `#[cfg()]` to
include either a unix or windows implementation of a common API
surface. This API surface is *not* exported directly in `libstd`, but is
instead used to bulid `std::os` and `std::io`.
Ultimately, the low-level details in `sys` will be exposed in a
controlled way through a separate platform-specific surface, but that
setup is not part of this patch.

This commit renames a number of extension traits for slices and string
slices, now that they have been refactored for DST. In many cases,
multiple extension traits could now be consolidated. Further
consolidation will be possible with generalized where clauses.
The renamings are consistent with the [new `-Prelude`
suffix](https://github.com/rust-lang/rfcs/pull/344). There are probably
a few more candidates for being renamed this way, but that is left for
API stabilization of the relevant modules.
Because this renames traits, it is a:
[breaking-change]
However, I do not expect any code that currently uses the standard
library to actually break.
Closes #17917

UdpSocket constructor methods now use ToSocketAddr trait instead of
SocketAddr.
[breaking-change]
|
|
TcpListener and TcpStream are converted to use ToSocketAddr trait in
their constructor methods.
[breaking-change]
|
|
This commit adds ToSocketAddr trait to std::io::net::ip module. This
trait is used for generic conversion from different types (strings,
(string, u16) tuples, etc.) into a SocketAddr instance. It supports
multiple output SocketAddresses when it is appropriate (e.g. DNS name
resolution).
This trait is going to be used by TcpStream, TcpListener and UdpSocket
structures.

- The `BytesContainer::container_into_owned_bytes` method has been removed
- Methods that used to take `BytesContainer` implementors by value, now take them by reference. In particular, this breaks some uses of Path:
``` rust
Path::new("foo") // Still works
path.join(another_path) -> path.join(&another_path)
```
[breaking-change]
---
Re: `container_into_owned_bytes`, I've removed it because
- Nothing in the whole repository uses it
- Takes `self` by value, which is incompatible with unsized types (`str`)
The alternative to removing this method is to split `BytesContainer` into `BytesContainer for Sized?` and `SizedBytesContainer: BytesContainer + Sized`, where the second trait only contains the `container_into_owned_bytes` method. I tried this alternative [in another branch](https://github.com/japaric/rust/commits/bytes) and it works, but it seemed better not to create a new trait for an unused method.
Re: Breakage of `Path` methods
We could use the idea that @alexcrichton proposed in #18457 (add blanket `impl BytesContainer for &T where T: BytesContainer` + keep taking `T: BytesContainer` by value in `Path` methods) to avoid breaking any code.

As part of the collections reform RFC, this commit removes all collections
traits in favor of inherent methods on collections themselves. All methods
should continue to be available on all collections.
This is a breaking change with all of the collections traits being removed and
no longer being in the prelude. In order to update old code you should move the
trait implementations to inherent implementations directly on the type itself.
Note that some traits had default methods which will also need to be implemented
to maintain backwards compatibility.

This commit enables implementations of IndexMut for a number of collections,
including Vec, RingBuf, SmallIntMap, TrieMap, TreeMap, and HashMap. At the same
time this deprecates the `get_mut` methods on vectors in favor of using the
indexing notation.

This commit adds the following impls:
impl<T> Deref<[T]> for Vec<T>
impl<T> DerefMut<[T]> for Vec<T>
impl Deref<str> for String
This commit also removes all duplicated inherent methods from vectors and
strings as implementations will now silently call through to the slice
implementation. Some breakage occurred at std and beneath due to inherent
methods removed in favor of those in the slice traits and std doesn't use its
own prelude,

The current terminology of "task failure" often causes problems when
writing or speaking about code. You often want to talk about the
possibility of an operation that returns a Result "failing", but cannot
because of the ambiguity with task failure. Instead, you have to speak
of "the failing case" or "when the operation does not succeed" or other
circumlocutions.
Likewise, we use a "Failure" header in rustdoc to describe when
operations may fail the task, but it would often be helpful to separate
out a section describing the "Err-producing" case.
We have been steadily moving away from task failure and toward Result as
an error-handling mechanism, so we should optimize our terminology
accordingly: Result-producing functions should be easy to describe.
To update your code, rename any call to `fail!` to `panic!` instead.
Assuming you have not created your own macro named `panic!`, this
will work on UNIX based systems:
grep -lZR 'fail!' . | xargs -0 -l sed -i -e 's/fail!/panic!/g'
You can of course also do this by hand.

This is a large spring-cleaning commit now that the 0.12.0 release has passed removing an amount of deprecated functionality. This removes a number of deprecated crates (all still available as cargo packages in the rust-lang organization) as well as a slew of deprecated functions. All `#[crate_id]` support has also been removed.
I tried to avoid anything that was recently deprecated, but I may have missed something! The major pain points of this commit is the fact that rustc/syntax have `#[allow(deprecated)]`, but I've removed that annotation so moving forward they should be cleaned up as we go.

This optimizes `read` for the case in which the number of bytes
requested is larger than the internal buffer. Note that the first
comparison occurs again right afterwards and should thus be free. The
second comparison occurs only in the cold branch.

Spring cleaning is here! In the Fall! This commit removes quite a large amount
of deprecated functionality from the standard libraries. I tried to ensure that
only old deprecated functionality was removed.
This is removing lots and lots of deprecated features, so this is a breaking
change. Please consult the deprecation messages of the deleted code to see how
to migrate code forward if it still needs migration.
