readdir() is preferred over readdir_r() on Linux and many other
platforms because it more gracefully supports long file names.  Both
glibc and musl (and presumably all other Linux libc implementations)
guarantee that readdir() is thread-safe as long as a single DIR* is not
accessed concurrently, which is enough to make a readdir()-based
implementation of ReadDir safe.  This implementation is already used for
some other OSes including Fuchsia, Redox, and Solaris.

See rust-lang#40021 for more details.  Fixes rust-lang#86649.  Fixes rust-lang#34668.

Bionic also guarantees that readdir() is thread-safe enough.

Improve Duration::try_from_secs_f32/64 accuracy by directly processing exponent and mantissa

Closes: rust-lang#90225

The methods now implement direct processing of exponent and mantissa, which should result in the best possible conversion accuracy (modulo truncation, i.e. float value of 19.995 ns will be represented as 19 ns).

…lections-examples, r=yaahc

Replace iterator-based construction of collections by `Into<T>`

Just a few quality of life improvements in the doc examples. I also removed some `Vec`s in favor of arrays.

…lbini

add OpenBSD platform-support page

It mentions x86_64, i686, aarch64 and sparc64 which are actively maintained and used on OpenBSD (binaries provided by standard package distribution on OpenBSD).

I volontary kept `powerpc-unknown-openbsd` unmentioned as it was added by `@Yn0ga` in rust-lang#82733, and I am unaware if it is functional or not (I doubt as I added libc support only few days ago, and std `c_char` signess was wrong). `@Yn0ga` maybe you comment on your `powerpc-unknown-openbsd` usage ?

Add x86_64-pc-windows-msvc linker-plugin-lto instructions

I had some trouble getting cross language LTO working for this target, in part because the very few links of documentation I could find were linux-centric and because of a few very specific errors I ran into. I'm not sure if this is the correct place to document this, but this is one of the first links I found when looking for documentation so it might be the best place for it.

fs: Use readdir() instead of readdir_r() on Linux and Android

See rust-lang#40021 for more details.  Fixes rust-lang#86649.  Fixes rust-lang#34668.
