We don't track them accurately when in onchaind, but we don't want to:
onchaind can be restarted at any time.
Once it's all settled, we're clear to clean them up.
Before this, valgrind could complain about deferncing hout->key.peer:

We are announcing that we are willing to accept incoming payments with
current_height + min_final_cltv_expiry + slack, assuming that the
sender adds some slack. In particular we'd reject the payment if
slack=0 which is allowed by the spec.

We save location where transaction was started, in case we try to nest.
There's now no error case; db_exec_mayfail() is the only one.
This means the tests need to override fatal() if they want to intercept
these errors.

This is a subset of a "bitcoind: wrap callbacks in transaction." from
the everything-in-transaction branch, but we need the ld pointer now.

These need to be different for testing the example in BOLT 11.
We also use the cltv_final instead of deadline_blocks in the final hop:
various tests assumed 5 was OK, so we tweak utils.py.

It crashes under valgrind, causing a valgrind error: valgrind gives us a

Normally, we get an error as soon as we send WIRE_REVOKE_AND_ACK. But if the
commit timer goes off, we get some extra cycles, during which the other side
can reconnect. In this case, we simply kill the channeld before it fails,
and never check for the permfail string.

This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out. This means we put #ifdefs in callers
in some places, but at least it's explicit.
We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.

There is a race we see sometimes under valgrind on Travis which shows
gossipd receiving the node_announce from master before it reads the
channel_announce from channeld, and thus fails. The simplest solution
is to send the channel_announce and channel_update to master as well,
so it can ensure it sends them to gossipd in order
