More vector->pointer conversion removals.

Add RandomNumberGenerator::random_vec, which takes an length n and
returns a new SecureVector with randomized contents of that size. This
nicely covers most of the cases where randomize was being called on a
vector, and is a little cleaner in the code as well, instead of
  vec.resize(length);
  rng.randomize(&vec[0], vec.size());
we just write
  vec = rng.random_vec(length);
