Split into two anchors.
This is a major change; instead of creating a mutual anchor (funding)
transaction, each side creates its own. We use escape transactions in
case anything goes wrong; these will be revoked later.

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

Remove signature leaking.
Alpha has segregated witnesses, so txid doesn't include the inputs.
That means we can create the first commit transaction before we sign
the anchor tx.
Bitcoin will need to do this differently: presumbly via new sipops
(a OP_CHECKSIG2VERIFY I imagine).

They sign, hash, and serialize differently.

Sort include lines (ignoring hacky cli test utils).
Put ccan first, openssl next, then standard headers, then locals.

Move bitcoin stuff into bitcoin subdir.
It's not very interesting if you're looking for LN code.

anchor: change is not an arbitrary output, but a pubkey we p2sh to.
Gets rid of the last pubkey user; they're generally deprecated.

Use pubkey structures in bitcoin_script, rather than protobufs.
This ensures we do checking beforehand, and keeps abstractions clear.

Make an explicit bitcoin_txid() call.
Neater than open-coding it. We still need the raw version for
signatures though.
