random32: seeding improvement
The rationale is: * use u32 consistently * no need to do LCG on values from (better) get_random_bytes * use more data from get_random_bytes for secondary seeding * don't reduce state space on srandom32() * enforce state variable initialization restrictions Note: the second paper has a version of random32() with even longer period and a version of random64() if needed.
