Now that the necessary associated types exist for the `IntoIterator` trait this
commit stabilizes the trait as-is as well as all existing implementations.

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`.
Another possibility is to check connecting to "127.0.0.1:1" and expects only `ConnectionRefused` error.

This commit exposes the `is_sep` function and `MAIN_SEP` constant, as
well as Windows path prefixes. The path prefix enum is safely exposed on
all platforms, but it only yielded as a component for Windows.
Exposing the prefix enum as part of prefix components involved changing
the type from `OsStr` to the `Prefix` enum, which is a:

* Move the type parameter on the `AsciiExt` trait to an associated type named
`Owned`.
* Move `ascii::escape_default` to using an iterator.
This is a breaking change due to the removal of the type parameter on the
`AsciiExt` trait as well as the modifications to the `escape_default` function
to returning an iterator. Manual implementations of `AsciiExt` (or `AsciiExt`
bounds) should be adjusted to remove the type parameter and using the new
`escape_default` should be relatively straightforward.

This commit makes several changes to `std::thread` in preparation for
final stabilization:
* It removes the ability to handle panics from `scoped` children; see
#20807 for discussion
* It adds a `JoinHandle` structure, now returned from `spawn`, which
makes it possible to join on children that do not share data from
their parent's stack. The child is automatically detached when the
handle is dropped, and the handle cannot be copied due to Posix
semantics.
* It moves all static methods from `std::thread::Thread` to free
functions in `std::thread`. This was done in part because, due to the
above changes, there are effectively no direct `Thread` constructors,
and the static methods have tended to feel a bit awkward.
* Adds an `io::Result` around the `Builder` methods `scoped` and
`spawn`, making it possible to handle OS errors when creating
threads. The convenience free functions entail an unwrap.
* Stabilizes the entire module. Despite the fact that the API is
changing somewhat here, this is part of a long period of baking and
the changes are addressing all known issues prior to alpha2. If
absolutely necessary, further breaking changes can be made prior to beta.
Closes #20807

This commit renames the features for the `std::old_io` and `std::old_path`
modules to `old_io` and `old_path` to help facilitate migration to the new APIs.
This is a breaking change as crates which mention the old feature names now need
to be renamed to use the new feature names.

This commit performs a stabilization pass over the `std::ascii` module taking
the following actions:
* the module name is now stable
* `AsciiExt` is now stable after moving its type parameter to an `Owned`
associated type
* `AsciiExt::is_ascii` is now stable
* `AsciiExt::to_ascii_uppercase` is now stable
* `AsciiExt::to_ascii_lowercase` is now stable
* `AsciiExt::eq_ignore_ascii_case` is now stable
* `AsciiExt::make_ascii_uppercase` is added to possibly replace
`OwnedAsciiExt::into_ascii_uppercase` (similarly for lowercase variants).
* `escape_default` now returns an iterator and is stable
* `EscapeDefault` is now stable
Trait implementations are now also marked stable.
Primarily it is still unstable to *implement* the `AsciiExt` trait due to it
containing some unstable methods.

The lifetime was previously, incorrectly unconstrained.
|
|
In most places this preserves the current API by adding an explicit
`'static` bound.
Notably absent are some impls like `unsafe impl<T: Send> Send for
Foo<T>` and the `std::thread` module. It is likely that it will be
possible to remove these after auditing the code to ensure restricted
lifetimes are safe.
More progress on #22251.

Some examples for `std::num::Float`
~~This is WIP for making examples for `f32`. This probably won't pass `make tidy` and I'm not sure which `f32` needs documentation. https://github.com/rust-lang/rust/issues/22025 shows 2 sets of `f32` which seems split between `core` and `std`. I'm not sure which should be documented but I started doing a couple from `std`. Easy to move if that's where they go...~~
~~Gotta build it eventually to actually see if the docs actually appear where I think they will or if I'm just disillusioned.~~

The test \"signal_reported_right\" send a signal `1` to `/bin/sh`, and check
the status code to check if the signal is reported right.
Under OpenBSD, the signal `1` (`SIGHUP`) is catched by `/bin/sh`,
resulting the test failed.
Use the uncatchable signal `9` (`SIGKILL`) for test.

This commit mostly replaces some of the uses of os::args with env::args.
This, for obvious reasons is based on top of #22400. Do not r+ before that lands.

Changes std::os::errno to return i32, the return type used by the function being delegated to.
This is my first contribution, so feel free to give me advice. I'll be happy to correct things.

`IntoIterator` now has an extra associated item:
``` rust
trait IntoIterator {
type Item;
type IntoIter: Iterator<Self=Self::Item>;
}
```
This lets you bind the iterator \"`Item`\" directly when writing generic functions:
``` rust
// hypothetical change, not included in this PR
impl Extend<T> for Vec<T> {
// you can now write
fn extend<I>(&mut self, it: I) where I: IntoIterator<Item=T> { .. }
// instead of
fn extend<I: IntoIterator>(&mut self, it: I) where I::IntoIter: Iterator<Item=T> { .. }
}
```
The downside is that now you have to write an extra associated type in your `IntoIterator` implementations:
``` diff
impl<T> IntoIterator for Vec<T> {
+ type Item = T;
type IntoIter = IntoIter<T>;
fn into_iter(self) -> IntoIter<T> { .. }
}
```
Because this breaks all downstream implementations of `IntoIterator`, this is a [breaking-change]

This snuck through my refactor.
Would it be worth the effort to have a test pass that attempts to lint the code for all targets, even if it's not feasible to actually build and test it?

`pipe(2)`, under FreeBSD and OpenBSD return a bidirectionnal pipe. So
reading from the writer would block (waiting data) instead of returning
an error.
like for FreeBSD, disable the test for OpenBSD.

Rather than stabilize on the current API, we're going to punt this
concern to crates.io, to allow for faster iteration.

`PathBuf` does implement `Hash`, but `Path` doesn't. This makes it
annoying if you have a `HashMap` with `PathBuf`s as keys, because
it means you have to convert a `Path` into a `PathBuf` and get a
reference to it simply to perform operations on the `HashMap`!
