        * glib.h: removed the GListAllocator type and its g_*_allocator_*()
        function variants (which weren't working anyways) in favour of a
        generic GAllocator type. new functions:
        g_allocator_new, g_allocator_free, g_slist_push_allocator,
        g_slist_pop_allocator, g_list_push_allocator, g_list_pop_allocator,
        g_node_push_allocator and g_node_pop_allocator.

        * gstring.c: removed bogus slist allocator code.
        * gtree.c: maintain own list of free tree nodes and don't waste
        GSLists for that, removed bogus slist allocator code.
        * glist.c: use GAllocators for node allocation.
        * gslist.c: use GAllocators for node allocation.
        * gnode.c: use GAllocators for node allocation.

        * gdataset.c: cleanups wrt automatic initialization.
