This assert was stronger than necessary (we assert the actual condition
later in this function). And it's vulnerable to a race condition
occurring in uv__work_done where we drain the work queue but still have

This code already had special handling for decoding utf-8
characters correctly for the UCS-2 conhost
(trailing incomplete bytes and characters > 0xFFFF).
Rather than trying to duplicate that, we can simply
delete the duplicate code-path and selectively disable
the parts that do not apply.

uv_fs_copyfile() calls fchmod() to change the target file's permissions
to the source file's permissions but that operation errors with EPERM on
CIFS shares unless they are mounted with the "noperm" option.
Since UNIX-style permissions don't make sense for CIFS anyway, let's
handle the error in libuv by recognizing that it's a CIFS share and
continuing when that is the case.
The same logic probably applies to (a subset of) FUSE file systems but
those haven't been whitelisted yet.

Before this commit, uv_sleep() made two library calls: sleep() to sleep
for the requested number of seconds, and then an usleep() call to sleep
for the remaining milliseconds. Make a single nanosleep() call instead.
Receiving a signal will wake up prematurely from sleep() but then
re-enter sleep mode again in usleep(), which seems undesirable.

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.

d2634be562/src/tcp_wrap.cc (L349) called from d2634be562/src/udp_wrap.cc (L567)
I suspect this may have been unreachable, and that it was guaranteed by the kernel to be `>= sizeof(struct sockaddr)`, so this should be a NFC simplification.

Platforms that support O_CLOEXEC have supported it for a long time
and don't need feature detection. Libuv can just assume it works as
advertised.
The feature detection was broken for old Linux kernels because they
don't report EINVAL for unknown open() flags, they simply open the
file without setting the FD_CLOEXEC flag.
Libuv could fix that by checking afterwards with fcntl() if the flag
was actually set but it doesn't support kernels that old in the first
place so let's simplify the logic.
