In the X9.31 PRNG, move the code that rekeys the cipher and generates V to

a new member function rekey, calling it from both reseed and add_entropy.
Previously add_entropy worked without this because the PRNG would reseed
itself automatically if it was not at the point when randomize() was called,
but once this was removed it was necessary to ensure a rekey kicked off,
if appropriate, when calling add_entropy.
