[PATCH v1 0/4] hashmap improvements

Here are a few small hashmap improvements, partly resulting from recent discussion of the config-cache topic.

Karsten Blees (4):
  hashmap: factor out getting an int hash code from a SHA1
  hashmap: improve struct hashmap member documentation
  hashmap: add simplified hashmap_get_from_hash() API
  hashmap: add string interning API
