[Murray Cumming <murrayc src gnome org>]

commit 9b90baa37d58f836fe1a23bf4bf6fdf2392ccded
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Mar 17 10:33:49 2017 +0100

    Glib::MiscUtils: Use std::vector instead of Glib::ArrayHandle<>.
    
    Using Glib::ArrayHandler<>::vector_to_array() and
    Glib::ArrayHandler<>::array_to_vector() instead, and only in the
    implementatoin instead of in the API.
