Summary:
In OpenSSL 3, EVP_PKEY_get0_* functions now return const pointers, breaking existing usage depending on mutable pointers returned by OpenSSL 1.x. This diff fix the errors

  1. Use auto type for return type of EVP_PKEY_get0_* functions instead of mutable pointer types.
  2. Some EVP_PKEY_get0_RSA are replaced with EVP_PKEY_get1_RSA in order to get a mutable pointer with the ownership.

See https://www.openssl.org/docs/man3.0/man7/crypto.html#LIBRARY-CONVENTIONS for the get_0 conventions
