   Applies "good password" rules to the secret pass phrase.

   We currently implement the following:

   Passwords must be at least OPIE_SECRET_MIN (10) characters long.
   Passwords must be at most OPIE_SECRET_MAX (127) characters long.

   N.B.: Passing NULL pointers to this function is a bad idea.
