Didn't generally fixup inside comments and the bech32 code: reformatting that
is just anti-social.

This is what all of this has been working towards: ripping out the handwoven
transaction handling. By removing the custom parsing we can finally switch
over to using `wally_tx` as sole representation of transactions in
memory. The commit is a bit larger but it's mostly removing setters and old
references to the input and output fields.

This is the second to last time I'm touching this file, just need to remove
the `tx->input` and `tx->output` swapping once they are removed.

The `wally_tx_input`s do not keep track of their input value, which means we
need to track them ourselves if we try to sign these transactions at a later
point in time.

This was suggested by Pierre-Marie as the solution to the 'same HTLC,
different CLTV' signature mismatch.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

permute_outputs is sometimes called with empty arguments from initial_commit_tx.
Make sure we guard against that case. We also do the same in permute_inputs for
good measure.

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

Turns out we want to permute transactions for the wallet too, so we
use void ** rather than assume we're shuffling htlc ** (and do inputs,
too!).

We used to have a permutation map; this reintroduces a variant which
uses the htlc pointers directly.
We need this because we have to send the htlc-tx signatures in output
order as part of the protocol: without two-stage HTLCs we only needed
to wire them up in the unilateral spend case so we simply brute-forced
the ordering.

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.

8a4246cb36 (permute: use BIP69 order) removed the invert_map change
from a25ba452f3 (permute_tx: fix horrible thinko.) but it's still
needed.
