Calls the given function for each of the key/value pairs in the
#GHashTable. The function is passed the key and value of each
pair, and the given @user_data parameter. The hash table may not
be modified while iterating over it (you can't add/remove
items). To remove all items matching a predicate, use
g_hash_table_foreach_remove().
See g_hash_table_find() for performance caveats for linear
order searches in contrast to g_hash_table_lookup().
