There are some nasty API problems that are caused by having to pass a
PRNG everywhere. The removal of the global PRNG was generated by a
desire to remove the global library state entirely. However the real
point of this was to remove the use of globally visible _mutable_
state; of the mutable state, the PRNG is probably the least important,
and the most useful to share. And it seems unlikely that thread
contention would be a major issue in the PRNG.
Add back a global PRNG to Library_State. Use lazy initialization, so
apps that don't ever use a PRNG don't need a seeding step. Then have
AutoSeeded_RNG call that global PRNG.
Offer once again
RandomNumberGenerator& Library_State::global_rng();
which returns a reference to the global PRNG.
This RNG object serializes access to itself with a mutex.
Remove the hack known as Blinding::choose_nonce, replace with using
the global PRNG to choose a blinding nonce
