The only use for these was to compute their txids so we could notify depth
in case of reorgs.

All of the callback functions were only using the tx to generate the txid again,
so we just pass that in directly and save passing the tx itself.
This is a simplification to move to the DB backed depth callbacks. It'd be
rather wasteful to read the rawtx and deserialize just to serialize right away
again to find the txid, when we already searched the DB for exactly that txid.

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.

Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

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).
