linux: support abstract unix sockets (#4030)

Add two new APIs for binding and connecting to abstract UNIX sockets.

Fixes: https://github.com/libuv/libuv/issues/4028

include: update outdated code comment (#4037)

I believe it's fair to say at this point that these functions are not
going to be removed in v0.12. They are still deprecated though.

linux: fs_read to use io_uring if iovcnt > IOV_MAX (#4023)

Just cap it to `IOV_MAX` as it's already done when performing reads
using the threadpool.

unix,win: replace QUEUE with struct uv__queue (#4022)

Recent versions of gcc have started emitting warnings about the liberal
type casting inside the QUEUE macros. Although the warnings are false
positives, let's use them as the impetus to switch to a type-safer and
arguably cleaner approach.

fs: use WTF-8 on Windows (#2970)

This allows working with valid filenames that are not well-formed
UTF-16. This is a superset of UTF-8, which does not error when it
encounters an unpaired surrogate but simply allows it.

test: remove erroneous RETURN_SKIP (#4015)

The threadpool_multiple_event_loops test already calls RETURN_SKIP when
needed. Remove it from the callback function where it isn't needed work
(nor works) and generates a build warning when compiling for qemu.

linux: fix WRITEV with lots of bufs using io_uring (#4004)

In the case of trying to write more than `IOV_MAX` buffers, the
`IORING_OP_WRITEV` operation will return `EINVAL`. As a temporal fix,
fallback to the old ways. In the future we might implement this by
linking multiple `IORING_OP_WRITEV` requests using `IOSQE_IO_LINK`.

freebsd: hard-code UV_ENODATA definition (#3999)

`FreeBSD` defines `ENODATA` in /usr/include/c++/v1/errno.h which is only visible
if C++ is the compilation unit. This can cause interop issues when
integrating libuv build with C on a C++ project. Avoid this issue by
directly defining with the value defined in the file previously
