Expand description

Replaces all matching keys with the new key. Returns true if at least one key was renamed. The key and new_key should be a null-terminated UTF-8 string. The new_key is copied and held by doc.

@warning This function takes a linear search time. If new_key already exists, it will cause duplicate keys.
