    gee: fix memory leak in GeeCollCXX

    gee_collection_iterator_get() always transfers ownership. The caller
    must g_free() (for strings) or unref (for GObjects) the returned value.

    The revised GeeCollCXX does this automatically, with GObject being the
default
    (relies on the GObject intrusive pointer template classes) and "gchar *" a
    special case in the template specialization of an utility traits class.

    The usage is almost as before. However, because of the reliance on
    SE_GOBJECT_TYPE, that macro must have been used for all types over which
    is to be iterated. Requires moving some definitions into header files
    where they can be shared.

    glib: fixed memory leak in some GAsyncReady helpers

    The callback was allocated with new for the duration of the operation
    and must be deleted. Was done via try/catch in some cases, but not all.

    The better solution is to use RAII and store the instance in an auto_ptr
    as soon as that is possible again.
