Use the Glib slice allocator for fixed-size objects The slice allocator, available since GLib 2.10, is more space-efficient than [g_]malloc. Since BarnOwl is obviously at the leading edge of space-efficient technology, this seems like a natural fit. Use it for every fixed-size object except owl_viewwin_search_data (which would need an extra destroy_cbdata function to g_slice_free it). Signed-off-by: Anders Kaseorg <andersk@mit.edu>
