This commit is an implementation of [RFC 979][rfc] which changes the meaning of
the count parameter to the `splitn` function on strings and slices. The
parameter now means the number of items that are returned from the iterator, not
the number of splits that are made.

This commit stabilizes a few remaining bits of the `io::Error` type:
* The `Error::new` method is now stable. The last `detail` parameter was removed
and the second `desc` parameter was generalized to `E: Into<Box<Error>>` to
allow creating an I/O error from any form of error. Currently there is no form
of downcasting, but this will be added in time.
* An implementation of `From<&str> for Box<Error>` was added to liballoc to
allow construction of errors from raw strings.
* The `Error::raw_os_error` method was stabilized as-is.
* Trait impls for `Clone`, `Eq`, and `PartialEq` were removed from `Error` as it
is not possible to use them with trait objects.
This is a breaking change due to the modification of the `new` method as well as
the removal of the trait implementations for the `Error` type.

* Added methods `PathBuf::as_path`, `OsString::as_os_str`,
`String::as_str`, `Vec::{as_slice, as_mut_slice}`.
* Deprecates `OsStr::from_str` in favor of a new, stable, and more
general `OsStr::new`.
* Adds unstable methods `OsString::from_bytes` and `OsStr::{to_bytes,
to_cstring}` for ergonomic FFI usage.

This commit cleans out a large amount of deprecated APIs from the standard
library and some of the facade crates as well, updating all users in the
compiler and in tests as it goes along.

This commit stabilizes the platform-specific `io` modules, specifically around
the traits having to do with the raw representation of each object on each
platform.
Specifically, the following material was stabilized:
* `AsRaw{Fd,Socket,Handle}`
* `RawFd` (renamed from `Fd`)
* `RawHandle` (renamed from `Handle`)
* `RawSocket` (renamed from `Socket`)
* `AsRaw{Fd,Socket,Handle}` implementations
* `std::os::{unix, windows}::io`
The following material was added as `#[unstable]`:
* `FromRaw{Fd,Socket,Handle}`
* Implementations for various primitives
There are a number of future improvements that are possible to make to this
module, but this should cover a good bit of functionality desired from these
modules for now. Some specific future additions may include:
* `IntoRawXXX` traits to consume the raw representation and cancel the
auto-destructor.
* `Fd`, `Socket`, and `Handle` abstractions that behave like Rust objects and
have nice methods for various syscalls.
At this time though, these are considered backwards-compatible extensions and
will not be stabilized at this time.
This commit is a breaking change due to the addition of `Raw` in from of the
type aliases in each of the platform-specific modules.

This commit stabilizes the `std::num` module:
* The `Int` and `Float` traits are deprecated in favor of (1) the
newly-added inherent methods and (2) the generic traits available in
rust-lang/num.
* The `Zero` and `One` traits are reintroduced in `std::num`, which
together with various other traits allow you to recover the most
common forms of generic programming.
* The `FromStrRadix` trait, and associated free function, is deprecated
in favor of inherent implementations.
* A wide range of methods and constants for both integers and floating
point numbers are now `#[stable]`, having been adjusted for integer
guidelines.
* `is_positive` and `is_negative` are renamed to `is_sign_positive` and
`is_sign_negative`, in order to address #22985
* The `Wrapping` type is moved to `std::num` and stabilized;
`WrappingOps` is deprecated in favor of inherent methods on the
integer types, and direct implementation of operations on
`Wrapping<X>` for each concrete integer type `X`.

This commit revises `path` and `os_str` to use blanket impls for `From`
on reference types. This both cuts down on the number of required impls,
and means that you can pass through e.g. `T: AsRef<OsStr>` to
`PathBuf::from` without an intermediate call to `as_ref`.
It also makes a FIXME note for later generalizing the blanket impls for
`AsRef` and `AsMut` to use `Deref`/`DerefMut`, once it is possible to do
so.

Now that support has been removed, all lingering use cases are renamed.

`PathBuf::new` have been changed. Use `PathBuf::from` instead.
Apply the same change for freebsd too, while here.

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.
Closes #22751
Closes #14433

and traits from the prelude. This functionality is now all deprecated and needs
to be removed to make way for other functionality like `Seek` in the `std::io`

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`.

- remove `core::num::UnsignedInt` and its re-export `std::num::UnsignedInt`
- move `collections` tests into its own crate: `collectionstest`
- copy `core::num::Float` methods into `impl f{32,64}`
Because this PR removes several traits, this is a [breaking-change], however functionality remains unchanged and breakage due to unresolved imports should be minimal. If you encounter an error due to an unresolved import, simply remove the import:
``` diff
fn main() {
- use std::num::UnsignedInt; //~ error: unresolved import `std::num::UnsignedInt`.
-
println!("{}", 8_usize.is_power_of_two());
}
```

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).

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 commit starts to organize the `std::os::$platform` modules and in the
process stabilizes some of the functionality contained within. The organization
of these modules will reflect the organization of the standard library itself
with extension traits for primitives in the same corresponding module.
The OS-specific modules will grow more functionality over time including
concrete types that are not extending functionality of other structures, and
these will either go into the closest module in `std::os::$platform` or they
will grow a new module in the hierarchy.
The following items are now stable:
* `os::{unix, windows}`
* `unix::ffi`
* `unix::ffi::OsStrExt`
* `unix::ffi::OsStrExt::{from_bytes, as_bytes, to_cstring}`
* `unix::ffi::OsString`
* `unix::ffi::OsStringExt::{from_vec, into_vec}`
* `unix::process`
* `unix::process::CommandExt`
* `unix::process::CommandExt::{uid, gid}`
* `unix::process::ExitStatusExt`
* `unix::process::ExitStatusExt::signal`
* `unix::prelude`
* `windows::ffi`
* `windows::ffi::OsStringExt`
* `windows::ffi::OsStringExt::from_wide`
* `windows::ffi::OsStrExt`
* `windows::ffi::OsStrExt::encode_wide`
* `windows::prelude`
The following items remain unstable:
* `unix::io`
* `unix::io::{Fd, AsRawFd}`
* `unix::fs::{PermissionsExt, OpenOptionsExt}`
* `windows::io`
* `windows::io::{Handle, AsRawHandle}`
* `windows::io::{Socket, AsRawSocket}`
* `windows::fs`
* `windows::fs::OpenOptionsExt`
Due to the reorgnization of the platform extension modules, this commit is a
breaking change. Most imports can be fixed by adding the relevant libstd module
in the `use` path (such as `ffi` or `fs`).
