We no longer need it anywhere. This simplifies things to the point where
we might as well just not include dust outputs as we go, rather than
explicitly removing them, which gets rid of remove_dust.c as well.

We just use a p2sh to a single address for the moment, but that's simply for
non-segwit wallets; we'll pay to whatever the other side specifies.

We need this for signing segwitness txs. Unfortunately, we don't have it
for transactions we received as hex, only ones we created; to make this safe
we use a pointer which is NULL if we don't know, and those will crash if
we try to sign or check their sigs.

We don't want to re-create them internally, ever.
The test-cli tools are patched to generate them all the time, but
they're not performance critical.

Most complex change was gather_updates(), which handles all the "what
is the current state of the channel" logic for our dumb test utils.
