- Pseudo-seed the PRNG in programs used for "make test"

  because otherwise BN_rand will fail unless DEVRANDOM works,
  which causes the programs to dump core because they
  don't check the return value of BN_rand (and if they
  did, we still couldn't test anything).

- add comment to some files that appear not to be used at all.
