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.

Corinna Vinschen 7d260cfac4 Cygwin: add transform_chars_af_unix helper 
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.

Corinna Vinschen fbdae2c216 Cygwin: reduce size of fhandler_cygdrive 
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.

Corinna Vinschen b79018ee3a Cygwin: encapsulate Winsock based fhandler_socket classes 
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.
