We could end up with multiple channel hints, which is a bit wasteful. We now
look for existing ones before adding a new one, and if one exists we use the
more restrictive parameters.

We're lucky that we can distinguish the severity of the failure based on the
failcode, so we bubble up the one with the maximum failcode, and let callers
inspect details if they need more information.
There is a race between `getroute` learning that our peer accepts TLVs and us
initiating the payment. Waiting for announcements ensures we always use TLVs,
matching our expectation in the test / plugin.
We can have quite detailed information about our local channels, so call
`listpeers` before the `getroute` call on the root payment, to seed that
information in the channel_hints.
Since we end up consolidating some of the return values for `pay` and
`paystatus` and change the public interface we need to add the compatibility
flag and guard the switchover behind it.
Trying to rework the TLV streams to have a more homogenous interface to work
with. This is by no means a complete implementation, just the groundwork that
is going to be used by the wire code generator to generate the specific
accessors, but it's enough so we can manipulate TLV streams in the onion and
later just switch to the generated ones.
We need to keep them around so we can inspect them later. We'll also need a
background cleanup every once in a while to free some memory. More on that in
a future commit.
We were just handwaving the partid generation, which broke some tests that
expected the first payment attempt to always have partid=0, so here we just
track the partids assigned in the payment tree, starting at 0.
The status of what started as a simple JSON-RPC call is now spread across an
entire tree of partial payments and payment attempts. So we collect the status
in a single struct in order to report back success of failure.
This is just for testing for now, TLV payload computation will come next. We
stage all the payloads in deserialized form so modifiers can modify them more
easily and serialize them only before actually calling `createonion`.
Te `sendonion` docs where claiming that the `first_hop` needs to specify a
`channel_id` whereas it should really be the `node_id` of the peer we are
trying to contact.
This is necessary so we can build the absolute locktimes in the next step. For
now just fetch the blockheight on each (sub-)payment, later we can reuse the
root blockheight if it ends up using too much traffic.
A payment is considered finished if it is in a final state (success or
failure) or all its sub-payments are finished. If that's the case we notify
`payment_finished` and bubble up through `payment_child_finished`, eventually
bubbling up to the root, which can then report success of failure back to the
RPC command that initiated the whole process.
This is likely a bit of overkill for this type of functionality, but it is a
nice first use-case of how functionality can be compartmentalized into
modifiers. If makes swapping retry mechanisms in and out really simple.
This should make it easy for JSON-RPC functions and modifiers to get the
associated data for a given modifier name. Useful if a modifier needs to
access its parent's modifier data, or in other functions that need to access
modifier data, e.g., when passing destination pointers into the `param()`
call.
This commit can be reverted/skipped once we have implemented all the logic and
have feature parity with the normal `pay`. It's main purpose is to expose the
unfinished functionality to test it, without completely breaking the existing
`pay` command.
@thestick613 noticed that since tor version below 0.3.2.2-alpha
will not support V3 ed25519 address formats, the error handling
is not that helpful in the error message from cli.
So now we add an hint.

Changelog-Added: We now install `lightning-hsmtool` for your `hsm_secret` needs.
See: https://github.com/ElementsProject/lightning/issues/3717#issuecomment-644844594
It seems reasonable to add this to the standard install, and to document it properly as well, hopefully we can fill in the documentation better later on.
We were assuming `wallet_channel_insert` that there cannot be a matching peer
if our in-memory representation isn't bound to it (`dbid == 0`). If we then
attempt to create the peer, and we already had one it'd cause a unique
constraint violation. As far as I can tell this could end up happening if we
have an uncommitted channel, and then exited without cleanup (`tal_destructor`
on the uncommitted channel not running). This could then leave the peer in the
DB. This is because the constraint that every peer has at least one channel is
not enforce at DB level, but rather in destructors that may or may not run.
Changelog-Fixed: Fixed a failing assertion if we reconnect to a peer that we had a channel with before, and then attempt to insert the peer into the DB twice.
