Previously random_integer and friends used the global PRNG object to get

random bits. Now they take a reference to a RandomNumberGenerator object.
This was applied several times out, so now the constructors to private
key objects also take a RandomNumberGenerator& argument. This is also true
for a number of randomized algorithms (Miller-Rabin, for instance).

You can get a reference to the global PRNG with
  global_state().prng_reference()

This is a provisional thing: and warning: it is not thread safe! If this
is a problem instead keep per-thread PRNGs and pass them were needed.
