sphinx: use struct pubkey.
It was using raw secp256k1_pubkey; we have better helpers for struct
pubkey.

struct secret: use everywhere.
We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

daemon/sphinx: support modern v0 hop payload.
This just means we put the outgoing_cltv_value where we used to put zeroes.
The old daemon simply ignores this, but the new one should check it as per
BOLT 4.

sphinx: Removing last vestiges of the end-to-end payload
So far this was simply set to a zero-length end-to-end payload. We

If I'd known how large this patch would be (though trivial), I'd
have done it in parts.
