Rusty Russell 963f6b5d67 invoice: add an optional local_offer_id.
This allows us to mark an offer used when an invoice derived from it
is paid, and importantly, avoid any other invoices for the offer being
paid.

Rusty Russell 83298c030a wallet: switch over to withdraw in module, remove lots of unused code.
This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.

This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined.  Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

lisa neigut 16656a85cf withdraw: refactor change output handling
We're not using the change_outnum for withdraw tx's (and the way
we were calculating it was broken as of the addition of 'multiple

entirely, and pushes the responsibility up to the caller to
include the change output in the output set if desired.

Consequently, we also remove the change output knowhow from hsmd.

These are generalized from our internal implementations.

The main difference is that 'struct json_escaped' is now 'struct

The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

This field was used by `pay` to hold the bolt11 description if the bolt11
string used `h` to hash the description (which nobody ever did).  If the
`h` field wasn't present, it could contain anything, as it wasn't checked.

It's really useful to have a label for payments (eg. '1 Cuban'), but adding
yet-another option would be painful, so we simply rename 'description'

You can figure this yourself by knowing the route, but it's better to report
it directly here.

Christian Decker 6d333f16cc wallet: Correctly handle forwards when channels or htlcs are deleted
The left join should make sure we still get the results but
referencing the fields and/or attempting to write them to the JSON-RPC
result will cause unforeseen problems. So just omit if we forgot
something.

Rusty Russell c8c3294a23 json-invoice: add routeboost, warnings.
We split json_invoice(), as it now needs to round-trip to the gossipd,
and uniqueness checks need to happen *after* gossipd replies to avoid
a race.

For every candidate channel gossipd gives us, we check that it's in
state NORMAL (not shutting down, not still waiting for lockin), that
it's connected, and that it has capacity.  We then choose one with
probability weighted by excess capacity, so larger channels are more
likely.

As a side effect of this, we can tell if an invoice is unpayble (no
channels have sufficient incoming capacity) or difficuly (no *online*
channels have sufficient capacity), so we add those warnings.

Christian Decker fbbc5899e4 invoices: Make the invoice_details more idiomatic
This seems like a premature optimization: it tried to cut down the number of
allocations by reusing the same `struct invoice_details` while iterating through
a number of results. But this sidesteps the checks by `valgrind` and we'd miss a
missing field that was set by the previous iteration.

Christian Decker 96352858d6 chaintopology: Simplify rescan offset computation
Simplification of the offset calculation to use the rescan parameter, and rename
of `wallet_first_blocknum`. We now use either relative rescan from our last
known location, or absolute if a negative rescan was given. It's all handled in
a single location (except the case in which the blockcount is below our
precomputed offset), so this should reduce surprises.
