Adapt to OpenSSL changes after the 1.1.0-pre6

Fix compiler errors and warnings. The order of parameters of
X509_{CRL,REQ}_get0_signature() has been changed, and certificate and
CRL time accessors have been reorganized: *_get_* functions are
deprecated and replaced by *_get0_* that return a const pointer.
