* 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 (cherry picked from commit e6680d78d943be4ee2d85e9d82cd8aa1350db882)
