  is not filled.

  * random.c (read_seed_file): New.

  (read_pool): Do an initial extra seeding when level 2 quality random

  used for key generation.

  cases when too much random is requested in one call.

  getrusage().

  the lowest random quality level.  Because they are public anyway we
  don't need stronger random and by this we do not drain the systems
