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.

As a side-effect of using amount_msat in gossipd/routing.c, we explicitly
handle overflows and don't need to pre-prune ridiculous-fee channels.

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

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_txid_to_hex() so it's reversed as people expect.

As per the pending spec change: the other implementations use version 2,
and the current best practice advice (from maaku) is to use the latest
defined tx version.

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.
