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).

Since we only care about the latest commits, we can simply associate a
state with each HTLC, rather than using queues of HTLCs associated
with each commitment transaction.
This works far better in the context of a database.
