Bad idea. A file hidden from directory listings is not seen by
rm either, so it never calls unlink for the file and a recursive
removal of the parent directory fails with "directory not empty".
Fix comments accordingly.

* Use correct cygwait/WFSO invocation to not die on cancel and signals
uncontrolled.
* Manage io handles under io_lock.
* Copy peer address to user space under SEH to avoid a resource leak.

Using TerminateThread potentially leaks resources. In our case,
the connect wait thread may be forcefully terminated after
having successfully opened a client side pipe handle. If this
occurs, we have a stale pipe server instance, so the pipe will
never be closed as long as the process lives.
Avoid this by changing the npfs handle to non-blocking, so we can
wait on a termination event object from inside the thread itself
and cleanly exit from the thread instead of terminating.

Depending on the exact circumstances, some erros are indicated
by different status codes. Add helper macros to handle them
together.

The handle to the device is never needed. As the name impies,
FSCTL_PIPE_WAIT works on the file system, not on the device level.
Drop opening the device and make sure to open only one handle to NPFS.

Linux and FreeBSD use int as well. In addition, this fixes an Ada
incompatiblity problem on 64-bit targets. See also GCC:

They are only used there anyway and it allows to use the AF_UNIX
macro without tweaking header files. While at it, improve
both constructors. The default constructor now creates the name
of an unnamed socket, the constructor taking parameters carefully
checks its input.

Locale modifier @cjkwide makes Unicode "ambiguous width" characters
wide. So ambiguous width characters can be enforced to have width 2
even in non-CJK locales. This gives e.g. users of "Powerline symbols"
the opportunity to adjust their width to the desired behaviour (and the
behaviour apparently expected by some tools) without having to set a CJK
locale and without losing consistence of terminal character width with
wcwidth/wcswidth locale width.
...plus lots of helper functions. Add comment to explain how everything
works. This comment will be improved while implementing the yet missing
parts.

This function is going to be used for transposing sun_path of
abstract sockets. This also adds a transposition of the NUL
character to tfx_chars since NUL-bytes in abstract socket names
are perfectly valid.

* check_reparse_point_target returns a path flag mask, rather than
just 1. Return PATH_SYMLINK | PATH_REP for symlinks and directory
mount points, PATH_SOCKET | PATH_REP for AF_UNIX sockets.
* Define Cygwin AF_UNIX socket reparse tag and GUID in ntdll.h.
