a4dfe3ad72 channel_state: encapsulate funding of channel in one place. 
This shows where funds are going at any time (fees vs to each side).
funding.c is mainly rewritten, and should be clearer now.

81bced330a protocol: move locktime into its own message type. 
We're going to want this for HTLC times, too.

eac3af06f1 protocol: switch to single-funder anchor model. 
Most complex change was gather_updates(), which handles all the "what
is the current state of the channel" logic for our dumb test utils.

aa79887d79 script: use the normalized delay script form for commit output. 
As documented in the paper; it's also two bytes shorter, and allows
us to use the exact same script for three cases.

8a4246cb36 permute: use BIP69 order. 
It's a canonical ordering, rather than a random shuffle.  Far simpler.

20bb6c65aa protocol fix: use locktime from *other* side. 
Which emerged clearly when setting one side's locktime differently than
the other.

Each side specifies the (minimum) time they need to notice a fraud attempt:
this constrains the *other* side.

29d0cdc3cd open-channel: use pubkey, not arbitrary script for final outout address. 
We need to pay to this from two places: on their side, it's a simple
payment, on our side, it's a complex timeout-or-mutual-or-hval script,
which doesn't lend itself to arbitrary scripts.

Use P2SH, of course.

This ensures we do checking beforehand, and keeps abstractions clear.
