Use new HASHMAP_INIT macro to simplify hashmap initialization
Now that hashamp has lazy initialization and a HASHMAP_INIT macro,
hashmaps allocated on the stack can be initialized without a call to
hashmap_init() and in some cases makes the code a bit shorter. Convert
some callsites over to take advantage of this.
