Corinna Vinschen d02f3a1238 Cygwin: sockets: Fix fstat on unnamed sockets
Calling fhandler_socket::fstat from fhandler_socket::fstat recursively
is not a good idea...

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.

First cut, still incomplete

* fhandler_socket is now base class for other socket classes
* fhandler_socket_inet handles AF_INET and AF_INET6 sockets
* fhandler_socket_local handles AF_LOCAL/AF_UNIX sockets
* finally get rid of fdsock by using set_socket_handle in accept4
* align file-related calls (fstat,  fstatvfs, fchown, fchmod, facl)
  to Linux.

Corinna Vinschen 7ae73be141 Cygwin: improve O_TMPFILE handling
Windows does not remove FILE_ATTRIBUTE_TEMPORARY by itself after a
file has been closed.  It's just some attribute which can be set or
removed at will, despite its purpose.

Apparently there are tools out there which use FILE_ATTRIBUTE_TEMPORARY
accidentally or wrongly, even Microsoft's own tools are affected.  In
the end, the filesystem is potentially full of files with this attribute
set.

Implement O_TMPFILE files with FILE_ATTRIBUTE_TEMPORARY and
FILE_ATTRIBUTE_HIDDEN set.  This combination is pretty unlikely.
