Corinna Vinschen cde2648c22 Cygwin: AF_UNIX: make sure connect wait thread is cleanly interruptible
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.

Corinna Vinschen 2f2a75b7bb Cygwin: AF_UNIX: fix creation of npfs handle
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.

Corinna Vinschen ae67198d55 Cygwin: move sun_name_t constructors into fhandler_socket_unix.cc
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.

Thomas Wolff f92f048528 Locale modifier @cjkwide to adjust ambiguous-width in non-CJK locales
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.

fhandler_cygdrive has a size of 696 bytes on x86_64, while the next
biggest fhandler type, fhandler_pty_master, is 584 bytes.  The members
responsible for the size are private to opendir/readdir/closedir usage.
fhandler_disk_file stores private readdir data in DIR->__d_internal
instead.  Use equivalent method with fhandler_cygdrive.  This drops
the size to 464 bytes.
