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.
