points to the API level, at which point the application handles managing
the RNG. This will allow removing the compiled-in global PRNG, and
make testing much simpler.

it was seeded if and only if the underlying PRNG was seeded. However if
the PRNG always returned as being seeded, we would never generate a V
value, etc (leaving them at the default zero). This would not occur with
any of Botan's built in PRNGs since their implementations require that
add_randomness be called at least once before is_seeded will return true.
However this is not an invariant of the general RandomNumberGenerator
interface.
Now, the X9.31 PRNG is only seeded after it has a) detected that the PRNG
is seeded, and b) generated a new random key and V vector.

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.

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>

universal: this prevented it from decoding application, context-specific,
or private-class constructions.
Add a new parameter to BER_Decoder::start_cons which specifies the expected
class type (default universal). The decoder still verifies that the
constructed bit is set in the class tag. This provides parity with the
interface to the DER encoder.

essentially a facade for the RNG object living in the global library state.
Rewrite all callers to directly invoke the global state object: this makes
it more clear what functions are actually accessing mutable state outside of
the normal reference graph (and thus, which functions will have to be
altered in order to remove this dependency). Other facades remain in place
for the configuration object and the memory allocator factory.

timer with an unspecified update rate and epoch. It is only used
inside the entropy sources to provide some timing-dependent
randomness. However, it is easier and basically 'as good' to treat the
timers as entropy sources in their own right and feed their output
directly into an entropy pool.

function.

(Library_State, in libstate.{h,cpp}). It causes numerous 'interesting'
problems with threads, etc, and the best solution here is to move to
more or less an object-capability model, where the only objects that
a piece of code can access are those which can be referenced through
its arguments.
First things first, remove the UI 'pulse' code. It is neither necessary
nor sufficient for writing proper GUI/event driven code using Botan, has
likely never been used in real code, and, given that, causes a distressing
amount of overhead in terms of function calls made.
