Thomas Martitz 4478b25ede core_alloc: Provide a tiny test allocation, which can be freed for debug purposes.
This allocation can be freed in the buflib debug menu (select it to free).
Doing a another allocation, e.g. by selecting another item in this debug menu
will cause compaction (all allocs move).
