Rusty Russell 18a9e5bda2 daemon: Implement encryption as per BOLT #1.
This uses libsodium (we could use openssl, but the required primitives
are only in 1.1.0 which is still in alpha).

It doesn't handle reconnections yet, either.

Rusty Russell 454a3867e5 BIP68 support (nSequence enforcement)
The latest version of the BIP doesn't use inversion, but does use
bitshifts.

It also uncovered a bug in the test scripts: the block timestamps
creep forward when we generate large numbers of blocks (UpdateTime
insists it be > GetMedianTimePast() so it's valid).  We need to take
this into account when waiting for the median to move (reduced it from
60 to 30 seconds, since that adds about 14 seconds).

Rusty Russell ed3f0115d6 protocol: fix horribly thinko, keep own secrets.
I had each side using the other side's hash secret.  That's a very
dumb idea, since it means you can steal from a unilateral close!

A's secret applies to A's commit transaction: it needs the
secret and B's final signature to steal funds, and that should
never happen (since A doesn't have the B's final signature, and
once A has given B the secret, they never broadcast the commit tx).

This makes the update a 4 step dance, since you need the new
revocation hash to make the other side's TX to sign.
