start cleaning the expansion code:

- change expandtree_* prefix to expand_ for better readability and
  because the structure might change at some point
- rename <>_free_nodes() to <>_free()
- remove unused <>_remove_node()
- refcounting has no purpose at all; just remove it as well as the
  decrement/increment functions, and replace the latter with <>_insert
- expandnode flags is only used to know if it's been processed or not,
  don't make it a flag but a simple field with clear name.
