The software impl of `acos` and `asin` depends on the `sqrt` op. Since support for `sqrt` in `f16`, `f80`, and `f128` has been added, the impl of `acos` and `asin` for `f16`, `f80`, and `f128` is now being supplemented.

This error is actually only ever directly returned from `std.posix.getcwd` (and only on POSIX systems, so never on Windows). Its inclusion in almost all of the error sets its currently found in is a leftover from when `std.fs.path.resolve` called `std.process.getCwdAlloc` (https://github.com/ziglang/zig/issues/13613).
Code used `ReturnType`, comment used `T` (which is what is used in similar functions).

The stated reason for this commit was cancelation didn't work. On
further review, we know why cancelation didn't work, and recent
enhancements on master branch make it easy to make it work.
Meanwhile, not using overlapped means that multiple threads cannot use
the same open socket handle. I also added line comments to explain the
choice in this revert commit.
This reverts commit fd3657bf8c.

Finite field elements can be in regular or Montgomery form, and
chaining different operations use to require manual and error-prone
conversions.
Now:
- `add`, `sub` and `mul` convert the second operand to match the
first operand's form
- `sq` and `pow` preserve the input's Montgomery form
- `toPrimitive` and `toBytes` return `UnexpectedRepresentation` if
the element is in Montgomery form, preventing incorrect serialization
This is fully backwards compatible and allows seamless chaining of
operations regardless of their representation.
The vast majority of libc functions return `c_int` for the return value,
when setting errno. This utility function is for those cases.
Other cases can hand-roll the logic, or additional helpers can be added.
IPPROTO_RAW (255) was missing from the Darwin/macOS IPPROTO struct,
even though it is defined in system headers and supported by the platform.
This is a commonly used protocol for raw IP sockets.
If the library isn't actually installed, `generated_bin` will be null,
causing this to panic about a missing dependency for itself; checking
for this state avoids this.
It can fail arbitrarily with ENOENT if the kernel happens to not have the FD in
its name cache. That makes it useless for our purposes.
