RAND_DRBG: add a callback data for entropy and nonce callbacks
The callback data allows passing context specific data from the
application of the DRBG to to the entropy callbacks.
This a rather specialized feature which is useful for implementing
known answer tests (KATs) or deterministic signatures (RFC6979),
which require passing a specified entropy and nonce for instantiating
the DRBG.
