Cygwin: split out fhandler_socket into inet and local classes

Browse Source 
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.
