* fix configure check: set DBUS_VA_COPY_FUNC correctly, and DBUS_VA_COPY_AS_ARRAY if no usable one was found
* add DBUS_VA_COPY_AS_ARRAY
* define DBUS_VA_COPY indirectly, cmakedefine plus variable does not work for me on windows, and is the wrong thing to do according to Allen. The undef seems unnecessary now, the address parsing test passes on windows, using mingw

dbus/dbus-sysdeps-win.c: Don't unconditionally #include <wspiapi.h>
* cmake/ConfigureChecks.cmake, cmake/config.h.cmake, configure.in:
check for wspiapi.h presence which isn't available (and unneeded) in mingw32
* dbus/dbus-sysdeps-win.c: use HAVE_WSPIAPI_H
* cmake/dbus/CMakeLists.txt: added missing files
* dbus/dbus-transport-win.c/.h: new files
* dbus/dbus-sysdeps-win.c,.h: added required _unix functions to make dbus compilable on win32
* dbus/dbus-sysdeps-win-utils.c,.h: moved some functions to dbus-sysdeps-win.c
* dbus-win.patch: removed applied or obsolate patches
Note: dbus-win32 is now compilable, no guarantee that it runs without any problems
