  1. Encapsulate PRNG usage 

    Allow for us to more easily change the PRNG representation.

At startup run the PRNG a few times to reduce initial correlation in bottom bits.  Ultimately, we should update the PRNG to something better.

  2. Add a replay allocator for ABA 

    Asan delays reallocation to increase the likelyhood of catching a UAF.  This adds a simple free list allocator
that tries to reuse allocations quickly to increase the chance of an ABA problem being detected.
