Core/Authserver: Auth cleanup phase 1a, the "stuff I ran across while making phase 2" commit.

- Did you know BigNumber quietly assumes every byte array it gets is little-endian, even though openssl bignums use big-endian? Now you do!
- In entirely unrelated news, make the above behavior explicit through a default-true boolean, same as existing GetBytes derivatives.
- Also, if you are in the enlightened openssl 1.1 crowd, there's no more endian wrangling involved, because openssl now does all of that for us. Progress!
