* 'master' of github.com:jedisct1/libsodium:
  Bench: don't tie the printed result to the number of iterations
  Make the number of iterations configurable; reduce the default
  Add an interesting test case for a custom randombytes_uniform implementation
  Add a benchmark mode
  randombytes test: restore the salsa20-based rng at the end, for benchmarks
  Indent
