htlcswitch: cap fee updates to max fee allocation
In this commit, we begin to enforce a maximum channel commitment fee for
channel initiators when attempting to update their commitment fee. Now,
if the new commitment fee happens to exceed their maximum, then a fee
update of the maximum fee allocation will be proposed instead if needed.

A default of up to 50% of the channel initiator's balance is enforced
for the maximum channel commitment fee. It can be modified through the
`--max-channel-fee-allocation` CLI flag.

multi: remove debug invoices
Debug invoices are rarely used nowadays, but keep asking for maintenance
every time refactoring in primarily the invoice registry occurs. We have
passed the cost/benefit tipping point, so therefore the debug invoice
concept is removed in this commit.

Previously the debughtlc flag also controlled whether hodl masks were
active. It is safe to remove that additional condition because the hodl
masks are still guarded by the dev build tag.

htlcswitch+invoices: always return incorrect_or_unknown_payment_details
In order to prevent information leaks by nodes probing with a payment
hash, this commit changes exit hop processing so that it always returns
incorrect_or_unknown_payment_details and leaves the prober in the dark
about whether an invoice actually exists.

multi: rename FailUnknownPaymentHash to FailIncorrectDetails
Align naming better with the lightning spec. Not the full name of the
failure (FailIncorrectOrUnknownPaymentDetails) is used, because this
would cause too many long lines in the code.

00814dc7c1 htlcswitch: pipeline settles to switch
This commit makes the outgoing link pipeline the settle to the
switch as soon as it receives it. Previously, it would wait for a
revocation before sending it, which caused increased latency on
payments as well as possibly never settling on the incoming link.
A duplicate settle is still sent to the switch, but it is handled
gracefully. A new AckEventTicker was added to the switch which
acknowledges any pending settle / fail entries in an outgoing
link's fwd pkgs in batch. This was needed in order to reduce the
number of db txn's which would have been incurred by acking whenever
we receive a duplicate settle without batching.

5f0fad85be multi: address lingering TODO by no longer wiping out local HTLCs on remote close
In this commit, we fix a lingering TOOD statement in the channel arb.
Before this commitment, we would simply wipe our our local HTLC set of
the HTLC set that was on the remote commitment transaction on force
close. This was incorrect as if our commitment transaction had an HTLC
that the remote commitment didn't, then we would fail to cancel that
back, and cause both channels to time out on chain.

In order to remedy this, we introduce a new `HtlcSetKey` struct to track
all 3 possible in-flight set of HTLCs: ours, theirs, and their pending.

We also we start to tack on additional data to all the unilateral close
messages we send to subscribers. This new data is the CommitSet, or the
set of valid commitments at channel closure time. This new information
will be used by the channel arb in an upcoming commit to ensure it will
cancel back HTLCs in the case of split commitment state.

Finally, we start to thread through an optional *CommitSet to the
advanceState method. This additional information will give the channel
arb addition information it needs to ensure it properly cancels back
HTLCs that are about to time out or may time out depending on which
commitment is played.

Within the htlcswitch pakage, we modify the `SignNextCommitment` method
to return the new set of pending HTLCs for the remote party's commitment
transaction and `ReceiveRevocation` to return the latest set of
commitment transactions on the remote party's commitment as well. This
is a preparatory change which is part of a larger change to address a
lingering TODO in the cnct.

Additionally, rather than just send of the set of HTLCs after the we
revoke, we'll also send of the set of HTLCs after the remote party
revokes, and we create a pending commitment state for it.

htlcswitch+router: move deobfuscator creation to GetPaymentResult call
In this commit we move handing the deobfuscator from the router to the
switch from when the payment is initiated, to when the result is
queried.

We do this because only the router can recreate the deobfuscator after a
restart, and we are preparing for being able to handle results across
restarts.

Since the deobfuscator cannot be nil anymore, we can also get rid of
that special case.

htlcswitch+router: define PaymentResult, GetPaymentResult

switch+router+server: move NextPaymentID to router
This commit moves the responsibility of generating a unique payment ID
from the switch to the router. This will make it easier for the router
to keep track of which HTLCs were successfully forwarded onto the
network, as it can query the switch for existing HTLCs as long as the
paymentIDs are kept.

The router is expected to maintain a map from paymentHash->paymentID,
such that they can be replayed on restart. This also lets the router
check the status of a sent payment after a restart, by querying the
switch for the paymentID in question.

link: increase expiry grace delta
This commit increase the expiry grace delta to a value above the
broadcast delta. This prevents htlcs from being accepted that would
immediately trigger a channel force close.

A correct delta is generated in server.go where there is access to
the broadcast delta and passed via the peer to the links.

htlcswitch/test: make unknown hash test independent of mock
In the TestChannelLinkMultiHopUnknownPaymentHash test, a preimage was
modified to trigger an unknown payment hash failure. The way the mock is
implemented, it would take the hash of that modified preimage and store
it. It basically stores a completely different invoice. For this test,
it is just as good to store no invoice at all.

multi: replace per channel sigPool with global daemon level sigPool
In this commit, we remove the per channel `sigPool` within the
`lnwallet.LightningChannel` struct. With this change, we ensure that as
the number of channels grows, the number of gouroutines idling in the
sigPool stays constant. It's the case that currently on the daemon, most
channels are likely inactive, with only a hand full actually
consistently carrying out channel updates. As a result, this change
should reduce the amount of idle CPU usage, as we have less active
goroutines in select loops.

In order to make this change, the `SigPool` itself has been publicly
exported such that outside callers can make a `SigPool` and pass it into
newly created channels. Since the sig pool now lives outside the
channel, we were also able to do away with the Stop() method on the
channel all together.

Finally, the server is the sub-system that is currently responsible for
managing the `SigPool` within lnd.

7535371238 htlcswitch: implement strict forwarding for locally dispatched payments
In this commit, we address an issue that could arise when using the
SendToRoute RPC. In this RPC, we specify the exact hops that a payment
should take. However, within the switch, we would set a constraint for
the first hop to be any hop as long as the first peer was at the end of
it. This would cause discrepancies when attempting to use the RPC as the
payment would actually go through another hop with the same peer. We fix
this by explicitly specifying the channel ID of the first hop.

Fixes #1500.
Fixes #1515.

htlcswitch: modify the InvoiceDatabase interface to allow specifying final payment amt
In this commit, we modify the InvoiceDatabase slightly to allow the link
to record what the final payment about for an invoice was. It may be the
case that the invoice actually had no specified value, or that the payer
paid more than necessary. As a result, it's important that our on-disk
records properly reflect this.

To fix this issue, the SettleInvoice method now also accepts the final
amount paid.

htlcswitch: add new TestForwardingAsymmetricTimeLockPolicies test
In this commit, we add a new test to the switch:
TestForwardingAsymmetricTimeLockPolicies. This test ensures that a link
has two channels, one of which has a greater CLTV delta than the latter,
that a payment will successfully be routed across the channels. Atm, the
test fails (including the fix to hop payload generation included in the
next commit).

Atm, due to the way that we check forwarding policies, we'll reject this
payment as we're attempting to enforce the policy of the incoming link
(cltv delta of 7), instead of that of the outgoing link (cltv delta of
6). As a result, atm, the incoming link checks if (incoming_timeout -
delta < outgoing_timeout). For the values in the test case: 112 - 7 <
106 -> 105 < 106, this check fails. The payload is proper, but the check
itself should be applied at the outgoing hop.

when to update their corresponding commitment fee. This prevents us from
oscillating the fee rate for our various commitment transactions.

link test: add TestChannelLinkWaitForRevocation
This commit adds a test where we trigger a situation which would
previously make the link think it was never in sync, and potentially
create a lot of empty state updates. This would happen if we were
waiting for a revocation, while still receiving updates from the remote.
Since in this case we could not ACK the updates because of the exhausted
revocation window, our local commitchain would extend, while the remote
chain would stall. When we finally got the revocation the local
commitment height would be far larger than the remote, and FullySynced
would return false from that point on.

The test makes the local commitment chain extend by 1 vs the remote,
which would earlier trigger another state update, and checks taht no
such state update is made.

that's destined for a multi-hop source sender, then we'll always package
the latest channel update along with it.

htlcswitch: move link trimming to link start up
In this commit, we fix a race in the set of TestChannelLinkTrimCircuits*
tests. Before this commit, we would trim the circuits in the htlcManager
goroutine. However, this was problematic as the scheduling order of
goroutines isn't predictable. Instead, we'll now trim the circuits in
the Start method.

Additionally, we fix a series of off-by-2 bugs in the tests themselves.

htlcswitch: fix TestUpdateForwardingPolicy
In this commit, we fix the TestUpdateForwardingPolicy test case after
the recent modification in the way we handling validating constraints
within the link. After the recent set of changes, Bob will properly use
his outgoing link to validate the set of fee related constraints rather
than the incoming link. As a result, we need to modify the second
channel link, not the first for the test to still be applicable.

on the socket to the remote peer.

htlcswitch: allow overpaying for incoming payments
In this commit, we relax the constraints on accepting an exit hop
payment a bit. We'll now accept any incoming payment that _at least_
pays the invoice amount. This puts us further inline with the
specification, which recommends that nodes accept overpayment by a
certain margin.

Fixes #1002.

c285bb5814 htlcswitch+peer: remove DecodeHopIterator from ChannelLinkConfig
In this commit, we remove the DecodeHopIterator method from the
ChannelLinkConfig struct. We do this as we no longer use this method,
since we only ever use the DecodeHopIterators method now.

htlcswitch: modify forwarding fee assertion to compare emperical fees
In this commit, we fix a bug that was uncovered by the recent change to
lnwire.MilliSatoshi. Rather than manually compute the diff in fees,
we’ll directly compare the fee that is given against the fee that we
expect.
