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).

2019-06-27man: clarify the 'random number generator must be seeded' requirementDr. Matthias St. Pierre
The manual pages require for some API functions that the 'random number generator must be seeded' before calling the function. Initially, this was meant literally, i.e. the OpenSSL CSPRNG had to be seeded manually before calling these functions. Since version 1.1.1, the CSPRNG is seeded automatically on first use, so it's not the responsibility of the programmer anymore. Still, he needs to be aware that the seeding might fail.
