  md5: Return a NULL pointer if MD5::raw_digest() is called early

This never happens since MD5::raw_digest()'s only caller, util::md5(),
always does it right. However, it's still an open invitation for someone
to read garbage past the end of a 1 byte array, or even worse, write
into it. I'd rather have us crash by dereferencing the null page in that
case instead.
