We had a discussion about this and the preference was to have get methods
retain const for various reasons.

Instead the DSA_SIG/ECDSA_SIG structures now no longer pre-allocate r/s so they
aren't immediately freed when you set them.

Do you have some examples of how this affects other structures? For RSA/DSA/DH
keys the fields are NULL initially unless I've missed something.
