A convenience method like fs::copy() should try to prevent pitfalls a normal user doesn't think about. In case of an empty umask, setting the file mode early prevents temporarily world readable or even writeable files, because the default mode is 0o666. In case the target is a named pipe or special device node, setting the file mode can lead to unwanted side effects, like setting permissons on `/dev/stdout` or for root setting permissions on `/dev/null`. copy_file_range() returns EINVAL, if the destination is a FIFO/pipe or a device like "/dev/null", so fallback to io::copy, too.

Tweak some error wording
Remove methods `Attribute::span` and `MetaItem::span` duplicating public fields
Ensure the core::ffi::VaList structure passes the improper_ctypes lint.
There's lots of comments in the code, but the main gist of this commit is that the acquisition of the global malloc lock on the `wasm32-unknown-unknown` target when threads are enabled will not spin on contention rather than block.
MIPS r6 is quite different with the previous version. It use some new target triples: mipsisa32r6-unknown-linux-gnu mipsisa32r6el-unknown-linux-gnu mipsisa64r6-unknown-linux-gnuabi64 mipsisa64r6el-unknown-linux-gnuabi64 This patch has been tested with Debian Port for mips64r6el, and the support of these triples also is included in llvm: https://reviews.llvm.org/rGe58c45a695f39004710b6ce940d489fee800dbd3
A `Def::Variant` should be considered as a function in mir pretty
printing. Each variant has a constructor that we must print.
Given the following enum definition:
```
pub enum TestMe {
X(usize),
}
```
We will need to generate a constructor for the variant `X` with a
signature that looks something like the following:
```
fn TestMe::X(_1: usize) -> TestMe;
```

…henkov Parse lifetimes that start with a number and give specific error Fix rust-lang#58786.
Do not accidentally treat multi-segment meta-items as single-segment Fixes rust-lang#55168 and many other regressions from rust-lang#50030 Basically, attributes like `#[any::prefix::foo]` were commonly interpreted as `#[foo]` due to `name()` successfully returning the last segment (this applies to nested things as well `#[attr(any::prefix::foo)]`).
Change `std::fs::copy` to use `copyfile` on MacOS and iOS `copyfile` on MacOS is similar to `CopyFileEx` on Windows. It supports copying resource forks, extended attributes, and file ACLs, none of which are copied by the current generic unix implementation. The API is available from MacOS 10.7 and iOS 4.3 (and possibly earlier but I haven't checked). Closes rust-lang#58895.

Use lifetime contravariance to elide more lifetimes in core+alloc+std
Sample:
```diff
- impl<'a, 'b, A: ?Sized, B: ?Sized> PartialEq<&'b mut B> for &'a mut A where A: PartialEq<B> {
+ impl<A: ?Sized, B: ?Sized> PartialEq<&mut B> for &mut A where A: PartialEq<B> {
#[inline]
- fn eq(&self, other: &&'b mut B) -> bool { PartialEq::eq(*self, *other) }
+ fn eq(&self, other: &&mut B) -> bool { PartialEq::eq(*self, *other) }
#[inline]
- fn ne(&self, other: &&'b mut B) -> bool { PartialEq::ne(*self, *other) }
+ fn ne(&self, other: &&mut B) -> bool { PartialEq::ne(*self, *other) }
}
```
[I didn't know this worked](https://internals.rust-lang.org/t/why-can-you-use-different-unconstrained-lifetimes-to-implement-traits/9544/2?u=scottmcm) until recently, but since defining methods contravariantly in their lifetimes this way has worked back to Rust 1.0, we might as well take advantage of combining it with IHLE.
