Subject: Remove both default arguments to the constructor of ANSI_X931_RNG. If
 the second argument was NULL, it would default to a new Randpool. But this
 introduces an annoying dependency: really it is the caller who is relying on
 Randpool. Make this explicit by passing a new Randpool pointer to the
 constructor in Library_State.

This will break all callers using ANSI_X931_RNG's constructors with
default arguments. To regain the previous behavior, change:
  ANSI_X931_RNG rng;
  ANSI_X931_RNG rng("/*cipher name*/");
to
  ANSI_X931_RNG rng(/*cipher name, default was AES-256 */, new Randpool);

You are free to pass another PRNG object if you like.

This make require inclusion of <botan/randpool.h>
