Comment (by nickm):

 My 'ed25519_ref10' branch now has an implementation of the curve25519-to-
 ed25519 key derivation approach, as I understand it. It is pretty simple,
 based on ed25519_ref10, and is done in a file named "keyconv.c". It will
 need review. I should finish that branch first.  (To be clear, this
 operation is a prerequisite for prop228, but is not sufficient for prop228
 in itself)
