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.

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.

...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.

Add constructors and new/delete operators to make sure sun_name_t
objects are allocated on the cygheap.

* 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.

* Rearrange includes and drop unneccessary ones.
* Don't pull in cygwin/socket.h into sys/un.h just to get
sa_family_t. Include sys/types.h and use __sa_family_t instead.
* start including Windows headers using the w32api/ path prefix

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.

* Make distinct from AF_LOCAL for testing purposes. This will have
to be reverted as soon as fhandler_socket_unix goes life.
* Move saw_reuseaddr flag back to fhandler_socket status

Insert another class fhandler_socket_wsock between fhandler_socket
and fhandler_socket_inet/fhandler_socket_local.
Also, add a new method fhandler::is_wsock_socket to allow asking
for sockets in general (is_socket) vs. Winsock-based sockets
(is_wsock_socket).
This allows to develop a new handler_socket_unix class as derived
class from fhandler_socket without any trace of wsock code left
in fhandler_socket.
While this is basically a temporary measure at this time, it may
prove useful for later interoperability with the upcoming Windows 10
AF_UNIX implementation at one point.
