This commit:
* Introduces `std::convert`, providing an implementation of
RFC 529.
* Deprecates the `AsPath`, `AsOsStr`, and `IntoBytes` traits, all
in favor of the corresponding generic conversion traits.
Consequently, various IO APIs now take `AsRef<Path>` rather than
`AsPath`, and so on. Since the types provided by `std` implement both
traits, this should cause relatively little breakage.
* Deprecates many `from_foo` constructors in favor of `from`.
* Changes `PathBuf::new` to take no argument (creating an empty buffer,
as per convention). The previous behavior is now available as
`PathBuf::from`.
* De-stabilizes `IntoCow`. It's not clear whether we need this separate trait.

The IP and socket address types all had `FromStr` implemented but the
implementations were not marked stable, nor was the error type returned ready to
be properly stabilized.
This commit marks the implementations of `FromStr` as stable and also renamed
the `ParseError` structure to `AddrParseError`. The error is now also an opaque
structure that cannot be constructed outside the standard library.

This commit stabilizes the `ErrorKind` enumeration which is consumed by and
generated by the `io::Error` type. The purpose of this type is to serve as a
cross-platform namespace to categorize errors into. Two specific issues are
addressed as part of this stablization:
* The naming of each variant was scrutinized and some were tweaked. An example
is how `FileNotFound` was renamed to simply `NotFound`. These names should not
show either a Unix or Windows bias and the set of names is intended to grow
over time. For now the names will likely largely consist of those errors
generated by the I/O APIs in the standard library.
* The mapping of OS error codes onto kinds has been altered. Coalescing no
longer occurs (multiple error codes become one kind). It is intended that each
OS error code, if bound, corresponds to only one `ErrorKind`. The current set
of error kinds was expanded slightly to include some networking errors.
This commit also adds a `raw_os_error` function which returns an `Option<i32>`
to extract the underlying raw error code from the `Error`.

Very minor fix: in `std::net::Ipv6Addr::new`, the documentation had an incomplete representation of the resulting address, missing the last two groups.
This commit performs a stabilization pass over the std::net module,
incorporating the changes from RFC 923. Specifically, the following actions were
taken:
Stable functionality:
* `net` (the name)
* `Shutdown`
* `Shutdown::{Read, Write, Both}`
* `lookup_host`
* `LookupHost`
* `SocketAddr`
* `SocketAddr::{V4, V6}`
* `SocketAddr::port`
* `SocketAddrV4`
* `SocketAddrV4::{new, ip, port}`
* `SocketAddrV6`
* `SocketAddrV4::{new, ip, port, flowinfo, scope_id}`
* Common trait impls for socket addr structures
* `ToSocketAddrs`
* `ToSocketAddrs::Iter`
* `ToSocketAddrs::to_socket_addrs`
* `ToSocketAddrs for {SocketAddr*, (Ipv*Addr, u16), str, (str, u16)}`
* `Ipv4Addr`
* `Ipv4Addr::{new, octets, to_ipv6_compatible, to_ipv6_mapped}`
* `Ipv6Addr`
* `Ipv6Addr::{new, segments, to_ipv4}`
* `TcpStream`
* `TcpStream::connect`
* `TcpStream::{peer_addr, local_addr, shutdown, try_clone}`
* `{Read,Write} for {TcpStream, &TcpStream}`
* `TcpListener`
* `TcpListener::bind`
* `TcpListener::{local_addr, try_clone, accept, incoming}`
* `Incoming`
* `UdpSocket`
* `UdpSocket::bind`
* `UdpSocket::{recv_from, send_to, local_addr, try_clone}`
Unstable functionality:
* Extra methods on `Ipv{4,6}Addr` for various methods of inspecting the address
and determining qualities of it.
* Extra methods on `TcpStream` to configure various protocol options.
* Extra methods on `UdpSocket` to configure various protocol options.
Deprecated functionality:
* The `socket_addr` method has been renamed to `local_addr`
This commit is a breaking change due to the restructuring of the `SocketAddr`
type as well as the renaming of the `socket_addr` method. Migration should be
fairly straightforward, however, after accounting for the new level of
abstraction in `SocketAddr` (protocol distinction at the socket address level,
not the IP address).
[breaking-change]
This commit deprecates the `count`, `range` and `range_step` functions
in `iter`, in favor of range notation. To recover all existing
functionality, a new `step_by` adapter is provided directly on `ops::Range`
and `ops::RangeFrom`.

This changes the type of some public constants/statics in libunicode.
Notably some `&'static &'static [(char, char)]` have changed
to `&'static [(char, char)]`. The regexp crate seems to be the
sole user of these, yet this is technically a [breaking-change]
This commit moves `std::env` away from the `std::old_io` error type as well as
the `std::old_path` module. Methods returning an error now return `io::Error`
and methods consuming or returning paths use `std::path` instead of
`std::old_path`. This commit does not yet mark these APIs as `#[stable]`.
This commit also migrates `std::old_io::TempDir` to `std::fs::TempDir` with
essentially the exact same API. This type was added to interoperate with the new
path API and has its own `tempdir` feature.
Finally, this commit reverts the deprecation of `std::os` APIs returning the old
path API types. This deprecation can come back once the entire `std::old_path`
module is deprecated.

This commit is an implementation of [RFC 823][rfc] which is another pass over
the `std::hash` module for stabilization. The contents of the module were not
entirely marked stable, but some portions which remained quite similar to the
previous incarnation are now marked `#[stable]`. Specifically:
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0823-hash-simplification.md
* `std::hash` is now stable (the name)
* `Hash` is now stable
* `Hash::hash` is now stable
* `Hasher` is now stable
* `SipHasher` is now stable
* `SipHasher::new` and `new_with_keys` are now stable
* `Hasher for SipHasher` is now stable
* Many `Hash` implementations are now stable
All other portions of the `hash` module remain `#[unstable]` as they are less
commonly used and were recently redesigned.
This commit is a breaking change due to the modifications to the `std::hash` API
and more details can be found on the [RFC][rfc].

The connect_error test check if connecting to "0.0.0.0:1" works (it
shouldn't). And in case of error, the test expects a ConnectionRefused
error.
Under OpenBSD, trying to connect to "0.0.0.0" isn't a ConnectionRefused:
it is an InvalidInput error.
The patch allow the error to be ConnectionRefused or InvalidInput.
This commit is an implementation of [RFC 807][rfc] which adds a `std::net`
module for basic neworking based on top of `std::io`. This module serves as a
replacement for the `std::old_io::net` module and networking primitives in
`old_io`.
[rfc]: fillmein
The major focus of this redesign is to cut back on the level of abstraction to
the point that each of the networking types is just a bare socket. To this end
functionality such as timeouts and cloning has been removed (although cloning
can be done through `duplicate`, it may just yield an error).
With this `net` module comes a new implementation of `SocketAddr` and `IpAddr`.
This work is entirely based on #20785 and the only changes were to alter the
in-memory representation to match the `libc`-expected variants and to move from
public fields to accessors.
