linux: introduce io_uring support (#3952)

Add io_uring support for several asynchronous file operations:

- read, write
- fsync, fdatasync
- stat, fstat, lstat

io_uring is used when the kernel is new enough, otherwise libuv simply
falls back to the thread pool.

Performance looks great; an 8x increase in throughput has been observed.

This work was sponsored by ISC, the Internet Systems Consortium.

unix: update uv_fs_copyfile() fallback logic

This commit fixes uv_fs_copyfile() in cases where an unknown error
occurs when copy-on-write is requested by setting
UV_FS_COPYFILE_FICLONE. The original approach tried to catch some of
the errors raised by the ioctl() call, assuming that sendfile() would
also fail in those cases. This is not necessarily true, as some
variants of ioctl() also raise EINVAL (some maybe EBADF), but sendfile()
works just fine.

This patch reverses the logic, falling back to sendfile() in any
case where ioctl() returns an error. In other words, it tries much
harder to make uv_fs_copyfile() work.

Related to that, the original approach returned UV_ENOTSUP
unconditionally in cases where ioctl() failed and
UV_FS_COPYFILE_FICLONE_FORCE was set. However, ioctl() may have
failed for other reasons than being not supported. The function
now returns the actual error raised by ioctl(), leaving it to the
caller to deal with it.

doc: improve uv_fs_readdir() cleanup docs

When cleaning up after uv_fs_readdir(), it is important to

former needs in order to do its job.
