227e66c469 rpc: Add PendingOpenChannel to SubscribeChannelEvents
This commit adds PendingOpenChannel to SubscribeChannelEvents stream in
the gRPC API.
This is useful for keeping track of channel openings that Autopilot does.
It can also be used for the non-initator side of a channel opening to keep
track of channel openings.

lntest: restart Alice after on-chain settle
To ensure lnd is able to pick up an on-chain preimage properly after a
restart, we suspend Alice and check that the payment is listed correctly
as succeeded after a restart.

lntest: fix macaroon paths
This change makes sure that all macaroons are stored in the same
folder. This makes it possible to use the lntest package in external
projects that use loop's lndclient library which currently assumes
that the admin macaroon and subserver macaroons are in the same sub
folder of lnd's data directory.

lntest+wait: replace sleeps in assertAmountSent
This commit constructs a helper closure assertAmountSent that can be
reused by other functions. The closure returns an error so that it can
be used with wait.NoError or the new wait.InvariantNoError. The latter
is added since the predicate could otherwise pass immediately for the
sphinx_replay_persistence tests, but change shortly after. It also
rounds out the wait package so that we offer all combinations of
predicate and no-error style waits.

67438bd006 lntest: Don't leak node's grpc conn
This changes the HarnessNode structure to hold onto the client grpc
connection made during startup so that it can close it during shutdown.

This is needed because the grpc.Dial function spins a new goroutine that
attempts to maintain an open connection to the target endpoint and
without calling Close() in the connection while shutting down the node
we leak this goroutine to the rest of the tests.

lnd test: fix csv mempool sweep time
Since CSV locked outputs specifies the first block where they are
allowed to be included, they can actually be added one block earlier
into the mempool.

This led to a flake, where the sweep tx was already in the mempool at
the time we mined the last block, causing the next mempool check to
fail.

lnd_test: fix race condition on simultanous force closes
This fixes an issue that would lead to a flake during intergration
tests. Carol would start up with a outdated state and attempt to force
close the channel. At the same time she would connect to Dave,
triggering the dataloss protection. Dave would respond by force closing
the channel, and Dave transaction would in some cases have a higher fee,
resulting Carol's tx being replaced.

We fix this by suspending Dave until Carol's close tx is mined.

rpc: update AbandonChannel to remove state from cnct, nursery and graph
In this commit, we update the `AbandonChannel` method to also remove the
state from the countract court as well as the channel graph. Abandoning
a channel is now a three step process: remove from the open channel
state, remove from the graph, remove from the contract court. Between
any step it's possible that the users restarts the process all over
again. As a result, each of the steps below are intended to be
idempotent.

We also update the integration test to assert that no channel is found
in the graph any longer. Before this commit, this test would fail as the
channel was still found in the graph, which can cause other issues for
an operational daemon.

Fixes #3716.

This commit beings the process of deprecating unsafe-disconnect. Many

lntest/itest: expand testSingleHopSendToRoute matrix
In this commit, we refactor the testSingleHopSendToRoute test to support
table driven tests for various endpoints and payment types. Currently
only the main rpcserver's SendToRoute is tested, so we also add
support the SendToRouteSync and the routerrpc's SendToRoute.

The tests are also modified to have each endpoint perform a single-hop,
single-shot MPP payment. This asserts that the Hop messages are being
properly unmarshalled and that setting correctly yields a successful
payment. At the momemnt the receiver does not actually verify or use the
MPP fields presented in the onion, though this test will be expanded
later as those pieces are assembled.

lntest/itest: wait for on-chain balance restore
We add a wait predicate to make sure the node's on-chain balance is
restored before continuing the restore test case.

This is needed since the DLP test scenario includes several restarts of
the node, and if the node isn't done scanning for on-chain balance
before the restart happens, it would be unlocked without a recovery
window, causing funds to be left undiscovered.

funding: dont's send ErrorCode on wire
Since the ErrorCodes are not part of the spec, they cannot be read by
other implementations.

Instead of only sending the error code we therefore send the complete
error message. This will have the same effect at the client, as it will
just get the full error instead of the code indicating which error it
is. It will also be compatible with other impls.

Note that the GRPC error codes will change, since we don't set them
anymore.

lntest/itest: resolve mempool flake in multi-hop htlc local timeout test
The test assumed that transactions would be broadcast and confirmed at
incorrect heights. Due to timing issues, it was possible for the test to
still succeed, resulting in a flake.

The test assumes that Bob will sweep a pending outgoing HTLC and commit
output back to their wallet. This commit ensures that these operations
are done when expected, i.e.:

1. Bob force closes the channel due to the HTLC timing out.
2. Once the channel is confirmed, Bob broadcasts their HTLC timeout
transaction.
3. Bob broadcasts their commit output sweep transaction once its CSV
expires.
4. Bob broadcasts their second layer sweep transaction for the timed out
HTLC once its CSV expires.

config: Adding RejectHTLC field in config struct

This commit adds a RejectHTLC field in the config struct in config.go.
This allows the user to run lnd as a node that does not accept onward

htlcswitch/switch: Adding a field RejectHTLC to the switch config

This commit adds a field RejectHTLC to the switch config. When the
switch receives an HTLC it will check this flag and if the HTLC is not
from the source hop, the HTLC will be rejected.

htlcswitch/switch: adding check for RejectHTLC flag and incomingChanID

This commit adds a check when receiving UpdateAddHTLC. The check looks
for the RejectHTLC flag set and whether the HTLC is from the sourceHop
(the local switch). If the HTLC is not from the sourceHop, then we
reject the HTLC and return a FailChannelDisabled error.

htlcswitch: always assume an onion error for malformed htlc failures
Previously a temporary channel failure was returning for unexpected
malformed htlc failures. This is not what we want to communicate to the
sender, because the sender may apply a penalty to us only.

Returning the temporary channel failure is especially problematic if we
ourselves are the sender and the malformed htlc failure comes from our
direct peer. When interpretating the failure, we aren't able to
distinguish anymore between our channel not having enough balance and
our peer sending an unexpected failure back.

Debug invoices are rarely used nowadays, but keep asking for maintenance

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.
