common/onion is going to need to use this for the case where it finds a blinding seed inside the TLV. But how it does ecdh is daemon-specific. We already had this problem for devtools/gossipwith, which supplied a special hsm_do_ecdh(). This just makes it more general. So we create a generic ecdh() interface, with a specific implementation which subdaemons and lightningd can use. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
