Similar to #31825 where the read/write limits were capped for files, this
implements similar limits when reading/writing networking types. On Unix this
shouldn't affect anything because the write size is already a `usize`, but on
Windows this will cap the read/write amounts to `i32::max_value`.
cc #31841
I am not entirely sure I have got everything right, but if it compiles it is ok probably...
I tested it with msvc x86_64 and gnu.
Somehow a lot of `EXCEPTION-*` constants are dead code when running test, no idea why.
I have put `#![cfg_attr(test, allow(dead_code))]` at the top for this.
The MinGW-based Python implementations would automatically do this, but if we
want to use Python from the official downloads our usage of `/` instead of `\`
can wreak havoc. In a few select locations just use `os.path.normpath` do do the
conversions properly for us.

I'm a bit iffy on the return type, but `Result` would also be a bit weird... The two error cases are `Unterminated` and `InteriorNul(usize)`.
I considered `from_chars(&[c_char])` but this meshes better with `as_bytes_with_nul()` and Rust code in general.
Should there also be a corresponding unsafe `from_bytes_unchecked` variant?
`ReadFile` and `WriteFile` take a DWORD (u32) for the length argument
which was erroneously cast from a usize causing truncation. This meant
methods like `write_all` and `read_exact` would unexpectedly fail if
given a buffer 4 GiB or larger.
We can instead just ask for `u32::MAX` bytes if the given buffer is too
big.
The `vfp2` option was a leftover from `armv6` compatibility features of the original armhf target.
Gcc defaults to `vfp3`on `armv7` hard-float linux systems so we should make it the default for rustc too.

Hello.
I came across some minor spelling mistakes while going through the documentation for the `Iterator` trait. Also includes a suggested styling fix.

Windows is not #[cfg(target_thread_local)] and as such should link
to the external symbol. But it fails with:
