Fix stale filename comment, const qualifier, and int-to-size_t casts

- test_preload.c: @file main.c -> @file test_preload.c
- show_alloc_mem.c, test_preload.c: hex array -> static const
- show_alloc_mem.c, test_preload.c, test_random.c: use size_t
  for sizeof-derived indices instead of casting to int
