This commit adds accessors for more fields in `fs::Metadata` on Windows
which weren't previously exposed. There's two sources of `fs::Metadata`
on Windows currently, one from `DirEntry` and one from a file itself.
These two sources of information don't actually have the same set of
fields exposed in their stat information, however. To handle this the
platform-specific accessors of Windows-specific information all return
`Option` to return `None` in the case a metadata comes from a
`DirEntry`, but they're guaranteed to return `Some` if it comes from a
file itself.
This is motivated by some changes in CraneStation/wasi-common#42, and
I'm curious how others feel about this platform-specific functionality!
Add support for UWP targets
Hi,
This pull request aims at adding support for UWP (Universal Windows Apps) platform.
A few notes:
- This requires a very recent mingw-w64 version (containing this commit and the previous related ones: e8c433c871 (diff-eefdfbfe9cec5f4ebab88c9a64d423a9))
- This was tested using LLVM/clang rather than gcc, and so far it assumes that LLVM/clang will be the native compiler. This is mostly due to the fact that the support for exceptions/stack unwinding for UWP got much more attention in libunwind
- The "uwp" part of the target needs support for it in the `cc-rs` & `backtrace-rs` crates. I'll create the MR there right after I submit this one and will link everything together, but I'm not sure what's the correct way of dealing with external dependencies in the context of rust
- Enabling import libraries and copying them across stages requires a change in cargo, for which I'll open a MR right after I submit this one as well
- The i686 stack unwinding is unsupported for now, because LLVM assumes SjLj, while rust seems to assume SEH will be used. I'm unsure how to fix this
Also, this is my first encounter with rust, so please bear with my code, it might not feel so idiomatic or even correct :)
I'm pretty sure there's a way of doing things in a cleaner way when it comes to win/c.rs, maybe having a UWP & desktop specific modules, and import those conditionally? It doesn't feel right to sprinkle `#[cfg(...)]` all over the place
Off course, I'll gladly update anything you see fit (to the extent of my abilities/knowledge :) )!
Thanks,

Use match ergonomics in Condvar documentation
Documentation was written before match ergonomics was merged. See #62857.
In short, replaces
```rust
let &(ref lock, ref cvar) = &*pair;
```
with
```rust
let (lock, cvar) = &*pair
```
in the docs of `std::sync::Condvar`.
Attempt to create sockets with the WSA_FLAG_NO_HANDLE_INHERIT flag, and
handle the potential error gracefully (as the flag isn't support on
Windows 7 before SP1)
Rename .cap() methods to .capacity()
As mentioned in #60316, there are a few `.cap()` methods, which seem out-of-place because such methods are called `.capacity()` in the rest of the code.
This PR renames them to `.capacity()` but leaves `RawVec::cap()` in there for backwards compatibility.
I didn't try to mark the old version as "deprecated", because I guess this would cause too much noise.
Test that maplike FromIter satisfies uniqueness
This PR adds a simple assertion to the `HashMap` and `HashSet` tests to ensure that uniqueness is satisfied when `FromIter`ing. This is useful for people who want to test their custom type against the Map/Set interfaces since they'll copy the tests wholesale but possibly miss this bug (where _they_ = _me_).
port rust for vxWorks
The supporting for vxWorks has been enabled in this branch. Although there are still a lots of work to do, I would like to upstream the code and fix the problems later.
Please let me know if there is anything I have to do before upstream the code.

I choice to not transmute because I think it's more unsafe and in case the structure change this code should always work.
