After [considerable
pushback](https://github.com/rust-lang/rfcs/issues/1451), it's clear
that there is a community consensus around providing `IpAddr` in the
standard library, together with other APIs using it.
This commit reverts from deprecated status directly to stable. The
deprecation landed in 1.6, which has already been released, so the
stabilization is marked for 1.7 (currently in beta; will require a backport).

This commit implements the stabilization of the custom hasher support intended
for 1.7 but left out due to some last-minute questions that needed some
decisions. A summary of the actions done in this PR are:
Stable
* `std::hash::BuildHasher`
* `BuildHasher::Hasher`
* `BuildHasher::build_hasher`
* `std::hash::BuildHasherDefault`
* `HashMap::with_hasher`
* `HashMap::with_capacity_and_hasher`
* `HashSet::with_hasher`
* `HashSet::with_capacity_and_hasher`
* `std::collections::hash_map::RandomState`
* `RandomState::new`
Deprecated
* `std::collections::hash_state`
* `std::collections::hash_state::HashState` - this trait was also moved into
`std::hash` with a reexport here to ensure that we can have a blanket impl to
prevent immediate breakage on nightly. Note that this is unstable in both
location.
* `HashMap::with_hash_state` - renamed
* `HashMap::with_capacity_and_hash_state` - renamed
* `HashSet::with_hash_state` - renamed
* `HashSet::with_capacity_and_hash_state` - renamed
Closes #27713

I don’t understand what the "flow information" of an IPv6 address is, but it looks separate from the scope ID. This was probably a copy/paste error.

This commit stabilizes and deprecates the FCP (final comment period) APIs for
the upcoming 1.7 beta release. The specific APIs which changed were:

* `From<CString> for Vec<u8>`
* `IntoStringError::into_cstring`
* `IntoStringError::utf8_error`
* `Error for IntoStringError`
Deprecated
* `Path::relative_from` - renamed to `strip_prefix`
* `Path::prefix` - use `components().next()` instead
* `os::unix::fs` constants - moved to the `libc` crate
* `fmt::{radix, Radix, RadixFmt}` - not used enough to stabilize
* `IntoCow` - conflicts with `Into` and may come back later
* `i32::{BITS, BYTES}` (and other integers) - not pulling their weight
* `DebugTuple::formatter` - will be removed
* `sync::Semaphore` - not used enough and confused with system semaphores

This wasn't done in https://github.com/rust-lang/rust/pull/29083 because attributes weren't parsed on fields of tuple variant back then.

This adds support for big endian and little endian PowerPC64.
make check runs clean apart from one big endian backtrace issue.

The first line (paragraph?) of a doc-comment is what rustdoc shows when listing items of a module.
What makes `Instant` and `SystemTime` different is important enough to be there. (Though feel free to bikeshed the wording.)

In 8d90d3f36871a00023cc1f313f91e351c287ca15 `BufStream`, the only
consumer of `InternalBufWriter`, was removed. As implied by the name,
this type is private, hence it is currently dead code.

The following PR updates libc version to latest commits for correctly support openbsd.
It corrects several points in rustc to be compatible with libc changes.

This adds the ability to override the default OOM behavior by setting a handler function. This is used by libstd to print a message when running out of memory instead of crashing with an obscure "illegal hardware instruction" error (at least on Linux).

Michael Ellerman pointed out that the system call for getrandom()
on PowerPC Linux is incorrect. This bug was in the powerpc32 port,
and was carried over to the powerpc64 port too.

I also re-enabled the use of `#[thread_local]` on AArch64. It was originally disabled in the PR that introduced AArch64 (#19790), but the reasons for this were not explained. `#[thread_local]` seems to work fine in my tests on AArch64, so I don't think this should be an issue.

`siginfo_si_addr()` function is used once, and the returned value is
casted to `usize`. So make the function returns a `usize`.
it simplifies OpenBSD case, where the return type wouldn't be a `*mut
libc::c_void` but a `*mut libc::c_char`.

use the `getentropy()` function instead of `syscall()` and
syscall-numbers.

* If the requested descriptors to inherit are stdio descriptors there
are situations where they will not be set correctly
* Example: parent's stdout --> child's stderr
parent's stderr --> child's stdout
* Solution: if the requested descriptors for the child are stdio
descriptors, `dup` them before overwriting the child's stdio
Example of a program which exhibits the bug:
```rust
// stdio.rs
use std::io::Write;
use std::io::{stdout, stderr};
use std::process::{Command, Stdio};
use std::os::unix::io::FromRawFd;
fn main() {
stdout().write_all("parent stdout\n".as_bytes()).unwrap();
stderr().write_all("parent stderr\n".as_bytes()).unwrap();
Command::new("sh")
.arg("-c")
.arg("echo 'child stdout'; echo 'child stderr' 1>&2")
.stdin(Stdio::inherit())
.stdout(unsafe { FromRawFd::from_raw_fd(2) })
.stderr(unsafe { FromRawFd::from_raw_fd(1) })
.status()
.unwrap_or_else(|e| { panic!("failed to execute process: {}", e) });
}
```
Before:
```
$ rustc --version
rustc 1.7.0-nightly (8ad12c3e2 2015-12-19)
$ rustc stdio.rs && ./stdio >out 2>err
$ cat out
parent stdout
$ cat err
parent stderr
child stdout
child stderr
```
After (expected):
```
$ rustc --version
rustc 1.7.0-dev (712eccee2 2015-12-19)
$ rustc stdio.rs && ./stdio >out 2>err
$ cat out
parent stdout
child stderr
$ cat err
parent stderr
child stdout
```

f64 methods have been stable since rust 1.0, but f32 never got stabilised.
I suggest backporting this to beta as well (needs changing stablilisation version then).
