Subject: [PATCH 4/4] sysdeps: Stop pretending _dbus_set_signal_handler is
 portable to Windows

None of the things we rely on in POSIX async signal handlers, such
as the existence of async-signal-safe write(), are portable to Windows,
so the async signal handlers that use this function are
#ifdef DBUS_UNIX anyway. Remove the unused stub function from the
Windows side, and move the declaration to the Unix-specific header.
