common: new directory for any shared objects.
To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

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).

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
don't have any plans of re-adding it for the moment, so let's get rid
of the unused code.

Use global secp256k1_ctx instead of passing it around.
If I'd known how large this patch would be (though trivial), I'd
have done it in parts.
