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).

This is required for onchaind: we want to watch all descendents by default,
as to do otherwise would be racy, which means we need to traverse the outputs
when a tx appears.

We don't report conflicts, just depths. So we report 0 if it's in a
main chain which loses to another, otherwise it's always positive.

Since any transaction with all segregated-witness inputs is non-malleable,
and all our transactions are that, we can remove normalized txids.

There isn't a single blockhash; we may be on multiple forks. But the one
caller which cares is commit_tx_depth(), which wants to know if the tx is
spendable yet. So that uses get_last_mediantime().

Rather than polling for interesting bitcoin txs via importaddress, we use
the chain topology to register our interest directly.x

With segregated witness, we can (in advance!) specify the txid or tx
output we want to watch, so convert to that now. For the moment it's
done by pretending we have normalized txids; that goes away after the
conversion.

This is only for the simple case where there are no HTLCs.
We group the current commit information together in the struct;
this involves a trivial transform from peer->cur_commit_theirsig to
peer->cur_commit.theirsig.

This is required for transactions which use OP_CSV to lock outputs for
a given amount of time: we need to know the mediantime of the block
they were included into.

We abort when this happens, but still worth testing.
This involves a refactor so we can allocate watches off a specific context,
for easy freeing when they're no longer wanted.
