Mutex and RwLock need RefUnwindSafe too
Incomplete, because I don't know what the appropriate stability annotation is here, but this is an attempt to bring the documentation for `std::panic` in line with reality. Right now, it says:
>Types like `&Mutex<T>`, however, are unwind safe because they implement poisoning by default.
But only `Mutex<T>`, not `&Mutex<T>`, is unwind-safe.

Mark Ipv4Addr is_unspecified as stable and provide reference.
Per [#27709 (comment)](https://github.com/rust-lang/rust/issues/27709#issuecomment-231280999), no RFC is needed here.
IPv4 "unspecified" has been defined in [Stevens], and has been part of the IPv4 stack for quite some time. This property should become stable, since this use of 0.0.0.0 is not going anywhere.
[Stevens][_UNIX Network Programming Volume 1, Second Edition_. Stevens, W. Richard. Prentice-Hall, 1998. p. 891]
Please let me know if I got the rustdoc wrong or something. I tried to be as terse as possible while still conveying the appropriate information.
This also has a slight impact on PR #34694, but that one came first, so this shouldn't block it, IMO.

std: Clean out deprecated APIs
This primarily removes a lot of `sync::Static*` APIs and rejiggers the
associated implementations. While doing this it was discovered that the
`is_poisoned` method can actually result in a data race for the Mutex/RwLock
primitives, so the inner `Cell<bool>` was changed to an `AtomicBool` to prevent
the associated data race. Otherwise the usage/gurantees should be the same
they were before.

Use hints with getaddrinfo() in std::net::lookup_host()
As noted in #24250, `std::net::lookup_host()` repeats each IPv[46] address in the result set. The number of repetitions is OS-dependent; e.g., Linux and FreeBSD give three copies, OpenBSD gives two. Filtering the duplicates can be done by the user if `lookup_host()` is used explicitly, but not with functions like `TcpStream::connect()`. What happens with the latter is that any unsuccessful connection attempt will be repeated as many times as there are duplicates of the address.
The program:
```rust
use std::net::TcpStream;
fn main() {
let _stream = TcpStream::connect("localhost:4444").unwrap();
}
```
results in the following capture:
[capture-before.txt](https://github.com/rust-lang/rust/files/352004/capture-before.txt)
assuming that "localhost" resolves both to ::1 and 127.0.0.1, and that the listening program opens just an IPv4 socket (e.g., `nc -l 127.0.0.1 4444`.) The reason for this behavior is explained in [this comment](https://github.com/rust-lang/rust/issues/24250#issuecomment-92240152): `getaddrinfo()` is not constrained.
Various OSS projects (I checked out Postfix, OpenLDAP, Apache HTTPD and BIND) which use `getaddrinfo()` generally constrain the result set by using a non-NULL `hints` parameter and setting at least `ai_socktype` to `SOCK_STREAM`. `SOCK_DGRAM` would also work. Other parameters are unnecessary for pure name resolution.
The patch in this PR initializes a `hints` struct and passes it to `getaddrinfo()`, which eliminates the duplicates. The same test program as above with this change produces:
[capture-after.txt](https://github.com/rust-lang/rust/files/352042/capture-after.txt)
All `libstd` tests pass with this patch.

Issue #34076: Removing reference to removed path.prefix() function
In the documentation for `std::path::Path`, there is a [reference](https://doc.rust-lang.org/std/path/struct.Path.html#method.is_absolute) to the `path.prefix()` function which has since been removed. The offending reference is now also removed.
First pull request, feedback welcome!

std: Stabilize APIs for the 1.11.0 release
Although the set of APIs being stabilized this release is relatively small, the
trains keep going! Listed below are the APIs in the standard library which have
either transitioned from unstable to stable or those from unstable to
deprecated.
Stable
* `BTreeMap::{append, split_off}`
* `BTreeSet::{append, split_off}`
* `Cell::get_mut`
* `RefCell::get_mut`
* `BinaryHeap::append`
* `{f32, f64}::{to_degrees, to_radians}` - libcore stabilizations mirroring past
libstd stabilizations
* `Iterator::sum`
* `Iterator::product`
Deprecated
* `{f32, f64}::next_after`
* `{f32, f64}::integer_decode`
* `{f32, f64}::ldexp`
* `{f32, f64}::frexp`
* `num::One`
* `num::Zero`
Added APIs (all unstable)
* `iter::Sum`
* `iter::Product`
* `iter::Step` - a few methods were added to accomodate deprecation of One/Zero
Removed APIs
* `From<Range<T>> for RangeInclusive<T>` - everything about `RangeInclusive` is
unstable
Closes #27739
Closes #27752
Closes #32526
Closes #33444
Closes #34152
cc #34529 (new tracking issue)

remove unneeded allow flag
There isn't anything deprecated being used in this function.
This built fine for me locally, but just to be sure, should check Travis.

Ignore unknown address types when looking up hosts
Previously, any function using a `ToSocketAddrs` input would fail if
passed a hostname that resolves to an address type different from the
ones recognized by Rust.
This also changes the `LookupHost` iterator to only include the known
address types, as a result, it doesn't have to return `Result`s any
more, which are likely misinterpreted as failed name lookups.
