#include <openssl/dsa.h>
Clarify the deprecation warnings in the docs There was recently an instance where a user was confused by the deprecation warnings in the docs. They believed the warning applied to the immediately preceding function declarations, when it fact it applied to the following function declarations. https://mta.openssl.org/pipermail/openssl-users/2021-December/014665.html We clarify the wording to make it clear that the warning applies to the following functions.

DSA: Make DSA_bits() and DSA_size() check that there are key parameters Without these check, a DSA structure without key parameters will cause these functions to crash. This is also the case in pre-3.0 OpenSSL, but since we now extract these data early, to cache them in the EVP_PKEY structure, the same crash happens earlier and much more internally.
