This is probably covered by our "channel capacity" heuristic which
requires the channel be significant, but best to be explicit and sure.

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.

We can tell this more generically because the count of revocations
received != count of commitments sent. This is the correct condition
which allows us to restore the test we had to eliminate in
c3cb7f1c85.

The wire protocol uses this, in the assumption that we'll never see feerates
in excess of 4294967 satoshi per kiloweight.
So let's use that consistently internally as well.

We currently scan through HTLCs: this isn't enough if we've only got a
feechange in the commitment, so use a flag (but keep both for now for
debugging).

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

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.
