Initialize all structs to 0 before using them.

This is consistent with the remaining code (which uses e.g. calloc) and makes
it easier to extend the structs in the future.
As a side effect it fixes several valgrind errors in hashmap_hash/hashmap_key_compare
caused by padding in the structures, but it is not a correct fix for that issue.
