Better document nullable X.509 getters.

When it is and isn't safe to assume an X509 field is non-NULL seems to
cause some confusion. (I often get requests to add NULL checks when
rewriting calling code.)

X.509 has surprisingly few optional fields, and we generally say
pointers are non-NULL unless documented. But that only works if we
remember to mention the nullable ones.
