Log Message:
Cleanup.
- Use GDKmalloc instead of GDKzalloc when we're immediately initializing anyway;
- Use GDKzalloc instead of GDMmalloc when we're immediately calling memset;
- Avoid using strcat when it's easy to do so (often we can use stpcpy);
- Use compound literals for initialization in more places.
