Subject: Prepare to provide DH_get0_{p,q,g,{priv,pub}_key}()

These are accessors that allow getting one specific DH member. They are
less error prone than the current getters DH_get0_{pqg,key}(). They
are used by many ports and will also be used in base for this reason.

Who can remember whether the pub_key or the priv_key goes first in
DH_get0_key()?
