commit a2b6231601c384bba043755bb58d500265ff6f1e
Author: Matt Caswell <matt at openssl.org>

Handle the case where there is no digest in an EVP_MD_CTX
EVP_MD_CTX_ctrl assumes that a digest has always been set. However in a
non-legacy EVP_DigestSign* operation this is not the case because the
digest is handled entirely by the underlying signature implementation.
This fixes one of the travis failures on the master branch.
