Rusty Russell 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.

Rusty Russell 3260fb2ed1 protocol: add commitment fee logic.
Both sides elect a commitment fee, and the lowest is chosen.  That means
you can't game the other side (but if you offer too low, then can error
out of course).

Fees are split 50-50 if possible: originally the whole fee has to be
paid by the (single) funder.  Neither side can withdraw funds which
would make them unable to pay fees.

Rusty Russell 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.
