Add more security features, e.g. chunk header xor-ing, better randomization, double-free checks, buffer overflow prevention, ...

- heap canaries - randomized allocations? (probably it isn't possible) - headers encryption - ~~better randomization of mmaped arenas (e.g. mimalloc: mi_unix_mmapx)~~ - Top chunk checks - Checks on chunks...
