2020-08-07rand_drbg: remove RAND_DRBG.Pauli
The RAND_DRBG API did not fit well into the new provider concept as implemented by EVP_RAND and EVP_RAND_CTX. The main reason is that the RAND_DRBG API is a mixture of 'front end' and 'back end' API calls and some of its API calls are rather low-level. This holds in particular for the callback mechanism (RAND_DRBG_set_callbacks()) and the RAND_DRBG type changing mechanism (RAND_DRBG_set()). Adding a compatibility layer to continue supporting the RAND_DRBG API as a legacy API for a regular deprecation period turned out to come at the price of complicating the new provider API unnecessarily. Since the RAND_DRBG API exists only since version 1.1.1, it was decided by the OMC to drop it entirely. Other related changes: Use RNG instead of DRBG in EVP_RAND documentation. The documentation was using DRBG in places where it should have been RNG or CSRNG. Move the RAND_DRBG(7) documentation to EVP_RAND(7).
