hashmap: add usage documentation explaining hashmap_free[_entries]()
The existence of hashmap_free() and hashmap_free_entries() confused me, and the docs weren't clear enough. We are dealing with a map table, entries in that table, and possibly also things each of those entries point to. I had to consult other source code examples and the implementation. Add a brief note to clarify the differences. This will become even more important once we introduce a new hashmap_partial_clear() function which will add the question of whether the table itself has been freed.
