Rollup merge of #22742 - alexcrichton:issue-22737, r=aturon
If the filename for a path is `None` then we know that the creation of the
parent directory created the whole path so there's no need to retry the call to
`create_dir`.
Rollup merge of #22729 - alexcrichton:ptr-stabilization, r=aturon
Specifically, the following actions were takend:
* The `copy_memory` and `copy_nonoverlapping_memory` functions
to drop the `_memory` suffix (as it's implied by the functionality). Both
functions are now marked as `#[stable]`.
* The `set_memory` function was renamed to `write_bytes` and is now stable.
* The `zero_memory` function is now deprecated in favor of `write_bytes`
directly.
* The `Unique` pointer type is now behind its own feature gate called `unique`
to facilitate future stabilization.
Rollup merge of #22727 - alexcrichton:prep-env, r=aturon
This commit moves `std::env` away from the `std::old_io` error type as well as
the `std::old_path` module. Methods returning an error now return `io::Error`
and methods consuming or returning paths use `std::path` instead of
`std::old_path`. This commit does not yet mark these APIs as `#[stable]`.
This commit also migrates `std::old_io::TempDir` to `std::fs::TempDir` with
essentially the exact same API. This type was added to interoperate with the new
path API and has its own `tempdir` feature.
Finally, this commit reverts the deprecation of `std::os` APIs returning the old
path API types. This deprecation can come back once the entire `std::old_path`
module is deprecated.
Rollup merge of #22596 - alexcrichton:fix-some-impls, r=huonw
This commit removes many unnecessary `unsafe impl` blocks as well as pushing the
needed implementations to the lowest level possible. I noticed that the bounds
for `RwLock` are a little off when reviewing #22574 and wanted to ensure that we
had our story straight on these implementations.
Rollup merge of #22792 - semarie:openbsd-unbreak-nacl, r=alexcrichton
The recent commit on liblibc for nacl break the compilation for OpenBSD (and Bitrig too, I think).
The problem is `ino_t` come from another block too now. This patch remove the extra declaration.
```
.../src/liblibc/lib.rs:98:9: 98:37 error: a type named `ino_t` has already been imported in this module [E0251]
.../src/liblibc/lib.rs:98 pub use types::os::arch::posix01::*;
^~~~~~~~~~~~~~~~~~~~~~~~~~~~
error: aborting due to previous error
```
@dhuseby do you have this problem too ? and if yes, does this patch correct it ?
Rollup merge of #22785 - nikomatsakis:issue-21750-normalization-with-regions, r=pnkfelix
Two changes:
1. Make traits with assoc types invariant w/r/t their inputs.
2. Fully normalize parameter environments, including any region variables (which were being overlooked).
The former supports the latter, but also just seems like a reasonably good idea.

added to the `offset` functions to require that the type is sized.
Rollup merge of #22539 - oli-obk:style_nitpicks, r=Manishearth
I tried to follow [the style guide][1] as much as possible. This is just from some random readings of the code, so no guarantees on completeness, even in the edited files.
Rollup merge of #22739 - tbu-:pr_error_net, r=alexcrichton
This affects the `set_non_blocking` function which cannot fail for Unix or
Windows, given correct parameters. Additionally, the short UDP write error case
has been removed as there is no such thing as \"short UDP writes\", instead, the
operating system will error out if the application tries to send a packet
larger than the MTU of the network path.
Rollup merge of #22623 - petrochenkov:optest, r=alexcrichton
Tests often use `vec![1, 2, 3]` instead of shorter and faster `[1, 2, 3]`.
This patch removes a lot of unnecessary `vec!`s. Hopefully, the tests will compile and run a bit faster.

Auto merge of #22172 - eddyb:almost-there, r=nikomatsakis
Adds `<module::Type>::method` support and makes `module::Type::method` a shorthand for it.
This is most of #16293, except that chaining multiple associated types is not yet supported.
It also fixes #22563 as `impl`s are no longer treated as modules in resolve.
Unfortunately, this is still a *[breaking-change]*:
* If you used a global path to a primitive type, i.e. `::bool`, `::i32` etc. - that was a bug I had to fix.
Solution: remove the leading `::`.
* If you passed explicit `impl`-side type parameters to an inherent method, e.g.:
```rust
struct Foo<T>(T);
impl<A, B> Foo<(A, B)> {
fn pair(a: A, b: B) -> Foo<(A, B)> { Foo((a, b)) }
}
Foo::<A, B>::pair(a, b)
// Now that is sugar for:
<Foo<A, B>>::pair(a, b)
// Which isn't valid because `Foo` has only one type parameter.
// Solution: replace with:
Foo::<(A, B)>::pair(a, b)
// And, if possible, remove the explicit type param entirely:
Foo::pair(a, b)
```
* If you used the `QPath`-related `AstBuilder` methods @hugwijst added in #21943.
The methods still exist, but `QPath` was replaced by `QSelf`, with the actual path stored separately.
Solution: unpack the pair returned by `cx.qpath` to get the two arguments for `cx.expr_qpath`.
Rollup merge of #22594 - alexcrichton:issue-22577, r=aturon
The windows/unix modules were currently inconsistent about the traits being
implemented for `DirEntry` and there isn't much particular reason why the traits
*couldn't* be implemented for `ReadDir` and `DirEntry`, so this commit ensures
that they are implemented.
Rollup merge of #22700 - nick29581:ints_hash, r=alexcrichton
fmt and hash are pretty straightforward I think. sync is a bit more complex. I thought one or two of the `isize`s ought to be `i32`s, but that would require a bunch of casting (the root cause being the lack of atomics other than isize/usize).
