f807b6a61e rollup merge of #22440: semarie/openbsd-connect_error
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

all platforms, but it only yielded as a component for Windows.

Exposing the prefix enum as part of prefix components involved changing

f492095eb4 rollup merge of #22024: alexcrichton/ascii
* 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.

d8f8f7a58c Revise std::thread semantics
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` 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

a2ebb24ee6 std: Rename io/path features with old_ prefix
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.

235f35b0b7 std: Stabilize the ascii module
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.

d7b5bc3c2f Update the libraries to reflect Send loosing the 'static bound.
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.

cae969e2a7 Remove the implicit 'static bound on Send.
Previously Send was defined as `trait Send: 'static {}`. As detailed in
https://github.com/rust-lang/rfcs/pull/458, the `'static` bound is not
actually necessary for safety, we can use lifetimes to enforce that more
flexibly.

`unsafe` code that was previously relying on `Send` to insert a
`'static` bound now may allow incorrect patterns, and so should be
audited (a quick way to ensure safety immediately and postpone the audit
is to add an explicit `'static` bound to any uses of the `Send` type).

When matching against strings/slices, we call the comparison function
for strings, which takes two string slices by value. The slices are
passed in memory, and currently we just pass in a pointer to the
original slice. That can cause misoptimizations because we emit a call
to llvm.lifetime.end for all by-value arguments at the end of a
function, which in this case marks the original slice as dead.

So we need to properly create copies of the slices to pass them to the
comparison function.

In trans_slice_vec we currently use arrayalloca, which gives us a
pointer to the element type with enough memory allocated for the
requested number of elements.  This works, but everywhere else we use
the [n x T] type for fixed size arrays and so we have to bitcast the
pointer here. Let's directly use the proper type for the allocation and
remove some code duplication along the way.

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.

8c639d3c6e Rollup merge of #22420 - posixphreak:fix-rustup-locale, r=brson
Since `tr` converts lowercase to uppercase according to system locale using `LC_CTYPE` environment variable; on some locales, rustup.sh fails to use correct variables names, thus deletes temporarily downloaded files and gives a meaningless error as shown below. This a simple fix which explictly sets `LC_CTYPE` as `C`.

Here is what happens without the fix:

I'm not exactly sure if setting LC_CTYPE is the best solution, but there's that.

d264ef2b11 Rollup merge of #22313 - japaric:iter, r=aturon
`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]

f58a1bfa98 Fix fallout in libsyntax from RFC 599. Clarity and efficiency seems to be mostly improved, to my eye.
Nonetheless, as this commit demonstrates, the previous commits was a [breaking-change].

In practice, breakage is focused on functions of this form:

```rust
fn foo(..., object: Box<FnMut()>)
````

where `FnMut()` could be any trait object type. The older scheme defaulted objects in argument
position so that they were bounded by a fresh lifetime:

```rust
fn foo<'a>(..., object: Box<FnMut()+'a>)
```

This meant that the object could contain borrowed data. The newer
scheme defaults to a lifetime bound of `'static`:

```rust
fn foo(..., object: Box<FnMut()+'static>)
```

This means that the object cannot contain borrowed data. In some cases, the best fix
is to stop using `Box`:

```rust
fn foo(..., object: &mut FnMut())
```

but another option is to write an explicit annotation for the `'a`
lifetime that used to be implicit.  Both fixes are demonstrated in
this commit.
