channeldb+routing: expose HTLCs in payment subscriptions
This commit modifies the FetchPayment method to return MPPayment structs
converted from the legacy on-disk format. This allows us to attach the
HTLCs to the events given to clients subscribing to the outcome of an
HTLC.

This commit also bubbles up to the routerrpc/router_server, by
populating HTLCAttempts in the response and extracting the legacy route
field from the HTLCAttempts.

multi: convert the existing channeldb.ChannelType uint8 into a bit field
In this commit, we convert the existing `channeldb.ChannelType` type
into a _bit field_. This doesn't require us to change the current
serialization or interpretation or the type as it is, since all the
current defined values us a distinct bit. This PR lays the ground work
for any future changes that may introduce new channel types (like anchor
outputs), and also any changes that may modify the existing invariants
around channels (if we're the initiator, we always have the funding
transaction).

channeldb: make copy for migrations
This commit is a direct copy of the complete channeldb package. It only
changes the package declaration at the top of every file. We make this
full copy so that review can be focused on the actual changes made.
Otherwise changes may drown in all the file moves.

Linting for the new package is disabled, as it contains lots of
pre-existing issues.

lnwallet: update channel state machine to be aware of tweakless commits
In this commit, we update the channel state machine to be aware of
tweakless commits. In several areas, we'll now check the channel's type
to see if it's `SingleFunderTweakless`. If so, then we'll opt to use the
remote party's non-delay based point directly in the script, skipping
any additional cryptographic operations. Along the way we move the
`validateCommitmentSanity` method to be defined _before_ it's used as is
cutomary within the codebase.

Notably, within the `NewUnilateralCloseSummary` method, we'll now _blank
out_ the `SingleTweak` value if the commitment is tweakless. This
indicates to callers the witness type they should map to, as the value
isn't needed at all any longer when sweeping a non-delay output.

We also update the signing+verification tests to also test that we're
able to properly generate a valid witness for the new tweakless
commitment format.

channeldb: ensure test for migration 9 is fully enclosed
In this commit, we ensure that the test for migration 9 uses the same
encoding/decoding functions as was present in the repo when the
migration was first added. Otherwise, the test will fail as it'll try to
use the decoding functions of master (migration 10 and onwards) rather
than the decoding function of migration 9.

channeldb: fix migration bug due to interplay between migration #9 and #10
In this commit, we fix an issue that was recently introduced as a result
of migration #10. The new TLV format ended up modifying the
serialization functions called in `serializePaymentAttemptInfo`.
Migration #9, also used this `serializePaymentAttemptInfo` method to
serialize the _new_ (pre TLV, but new payment attempt structure) routes
into the database during its migration. However, migration #10 failed to
copy over the existing unmodified `serializePaymentAttemptInfo` method
into the legacy serialization for migration #9. As a result, once
migration #9 was run, the routes/payments were serialized using the
_new_ format, rather than the format used for v0.7.1. This then lead to
de-serialization either failing, or causing partial payment corruption
as migration #10 was expecting the "legacy" format (no TLV info).

We fix this issue by adding a new fully enclosed
`serializePaymentAttemptInfoMigration9`method that will be used for
migration #9. Note that our tests didn't catch this, as they test the
migration in isolation, rather than in series which is how users will
encounter the migrations.

Fixes #3463.

invoices: replay awareness
Previously the invoice registry wasn't aware of replayed htlcs. This was
dealt with by keeping the invoice accept/settle logic idempotent, so
that a replay wouldn't have an effect.

This mechanism has two limitations:

1. No accurate tracking of the total amount paid to an invoice. The total
amount couldn't just be increased with every htlc received, because it
could be a replay which would lead to counting the htlc amount multiple
times. Therefore the total amount was set to the amount of the first
htlc that was received, even though there may have been multiple htlcs
paying to the invoice.

2. Impossible to check htlc expiry consistently for hodl invoices. When
an htlc is new, its expiry needs to be checked against the invoice cltv
delta. But for a replay, that check must be skipped. The htlc was
accepted in time, the invoice was moved to the accepted state and a
replay some blocks later shouldn't lead to that htlc being cancelled.
Because the invoice registry couldn't recognize replays, it stopped
checking htlc expiry heights when the invoice reached the accepted
state. This prevents hold htlcs from being cancelled after a restart.
But unfortunately this also caused additional htlcs to be accepted on an
already accepted invoice without their expiry being checked.

In this commit, the invoice registry starts to persistently track htlcs
so that replays can be recognized. For replays, an htlc resolution
action is returned early. This fixes both limitations mentioned above.

channeldb+invoices: move invoice accept or settle logic into registry
As the logic around invoice mutations gets more complex, the friction
caused by having this logic split between invoice registry and channeldb
becomes more apparent. This commit brings a clearer separation of
concerns by centralizing the accept/settle logic in the invoice
registry.

The original AcceptOrSettle method is renamed to UpdateInvoice because
the update to perform is controlled by the callback.

channeldb+invoices: add invoice htlcs
This commit adds a set of htlcs to the Invoice struct and
serializes/deserializes this set to/from disk. It is a preparation for
accurate invoice accounting across restarts of lnd.

A migration is added for the invoice htlcs.

In addition to these changes, separate final cltv delta and expiry
invoice fields are created and populated. Previously it was required
to decode this from the stored payment request. The reason to create
a combined commit is to prevent multiple migrations.

The main purpose is to be able to iterate over these fast when prune is
needed without the need for iterating the whole graph.

The entry points for accessing this index are:
1. When updating ChannelEdgePolicy - insert an entry.
2. When deleting ChannelEdge - delete the associated entries.
3. When querying for disabled channels - implemented DisabledChannelIDs

migrateOutgoingPayments moves the OutgoingPayments into a new bucket format
where they all reside in a top-level bucket indexed by the payment hash. In
this sub-bucket we store information relevant to this payment, such as the

To avoid that the router resend payments that have the status InFlight (we
cannot resume these payments for pre-migration payments) we delete those
statuses, so only Completed payments remain in the new bucket structure.

channeldb/payments+control_tower: split OutgoingPayments
This commit changes the format used to store payments within the
DB. Previously this was serialized as one continuous struct
OutgoingPayment, which also contained an Invoice struct we where only
using a few fields of. We now split it up into two simpler sub-structs
CreationInfo, AttemptInfo and PaymentPreimage.

We also want to associate the payments more closely with payment
statuses, so we move to this hierarchy:

There's one top-level bucket "sentPaymentsBucket" which contains a set
of sub-buckets indexed by a payment's payment hash. Each such sub-bucket
contains several fields:
paymentStatusKey -> the payment's status
paymentCreationInfoKey -> the payment's CreationInfo.
paymentAttemptInfoKey -> the payment's AttemptInfo.
paymentSettleInfoKey -> the payment's preimage (or zeroes for
non-settled payments)

The CreationInfo is information that is static during the whole payment
lifcycle. The attempt info is set each time a new payment attempt
(route+paymentID) is sent on the network. The preimage is information
only known when a payment succeeds.  It therefore makes sense to split
them.

We keep legacy serialization code for migration puproses.

watchtower/wtdb: add CSessionStatus field to ClientSession
This commit adds persisted status bit-field to ClientSessions, that can
be used to modify behavior of their handling in the client. Currently,
only a default CSessionActive status is defined. However, the intention
is that this could later be used to signal that a session is abandoned
without needing to perform a db migration to add the field. As we move
forward with testing, this will likely be useful if a session gets
borked and we need a simple method of the client to temporarily ignore
certain sessions.

The field may be useful in signaling other types of status changes,
though this was the primary motivation that warranted the addition.

cnct+htlcswitch+invoices: move invoice parameter check out of link
This commit is the final step in making the link unaware of invoices. It
now purely offers the htlc to the invoice registry and follows
instructions from the invoice registry about how and when to respond to
the htlc.

The change also fixes a bug where upon restart, hodl htlcs were
subjected to the invoice minimum cltv delta requirement again. If the
block height has increased in the mean while, the htlc would be canceled
back.

Furthermore the invoice registry interaction is aligned between link and
contract resolvers.

channeldb+routing: refactor DeleteChannelEdge to use ChannelID
In this commit, we refactor DeleteChannelEdge to use ChannelIDs rather
than ChannelPoints. We do this as the only use of DeleteChannelEdge is
when we are pruning zombie channels from our graph. When running under a
light client, we are unable to obtain the ChannelPoint of each edge due
to the expensive operations required to do so. As a stop-gap, we'll
resort towards using an edge's ChannelID instead, which is already
gossiped between nodes.

channeldb/graph: remove MarkEdgeZombie
This commit removes the MarkEdgeZombie method from channeldb. This
method is currently not used in any live code paths in production, and
is only used in unit tests. However, incorrect usage of this method
could result in an edge being present in both the zombie and channel
indexes, which deviates from any state we would expect to see in
production. Removing the method will help mitigate the potential for
writing incorrect unit tests in the future, by forcing zombie edges to
be created via the relevant, production APIs, e.g. DeleteChannelEdge.

The existing unit tests that use this method have been modified to use
the DeleteChannelEdge instead. No regressions were discovered in the
process.

channeldb/graph: skip unknown edges in FetchChanInfos
This commit modifies FetchChanInfos to skip any channels that are not in
the graph at the time of the call. Currently the entire call will fail
if the edge is not found, which stalls a gossip sync in the following
scenario:

 1. Remote peer queries for a channel range
 2. We return the set of channel ids in that range
 3. A channel from that set is removed from the graph, e.g. via close.
 4. Remote peer queries for removed edge, causing the query to fail.

To remedy this, we will now skip any edges that are not known in the
database at the time of the query. This prevents the syncer state
machines from halting, which otherwise could only be resolved by
disconnecting and reconnecting.

channeldb+routing: extend edge lookup methods with zombie index check
In this commit, we extend the graph's FetchChannelEdgesByID and
HasChannelEdge methods to also check the zombie index whenever the edge
to be looked up doesn't exist within the edge index. We do this to
signal to callers that the edge is known, but only as a zombie, and the
only information that we have about the edge are the node public keys of
the two parties involved in the edge.

In the event that an edge does exist within the zombie index, we make
an additional check on edge policies to ensure they are not within the
router's pruning window, indicating that it is a fresh update.

When we insert a channel shell, we re-create the original link node, and

70d3fc640a channeldb/db: prevent filtering channels with unconfirmed close txs
In this commit, we address an issue with the FetchWaitingCloseChannels
method where it would not properly return channels that are unconfirmed
and also have an unconfirmed closing transaction because they were
filtered out. We fix this by fetching channels that remain unconfirmed
that are also waiting for a confirmed closing transaction.

This will allow the recently added test TestFetchWaitingCloseChannels to
pass.

409efd1361 channeldb/channel_test: add TestFetchWaitingCloseChannels
In this commit, we add a test case for FetchWaitingCloseChannels to
ensure it behaves as intended. Currently, this test fails due to not
fetching channels which are pending to be closed but are also pending to
be opened. This will be fixed in the following commit and should allow
the test to pass.

channeldb: ensure channel buckets are only created once
In this commit, we ensure that we only create the sub-bucket for
channels once: at the time of creation. We do this as otherwise it's
possible that a method that mutates a channel's state is called after it
has already been closed on-chain, leading to the channel bucket being
recreated.

channeldb: fix bug in migration from 0.4 to 0.5
In this commit, we fix a bug in the latest database migration when
migrating from 0.4 to 0.5. There's an issue in bolt db where if one
deletes a bucket that has a key with a nil value, it thinks that's a sub
bucket and attempts a bucket deletion. This will fail as it's not
actually a sub-bucket.  We get around this by using a cursor to manually
delete items in the
bucket.

Fixes #1907.

channeldb: relax bucket assumptions for latest db migration
In this commit, we no longer assume that the bucket hierarchy has been
created properly when applying the latest DB migration. On older nodes
that never obtained a channel graph, or updated _before_ the query sync
stuff was added, then they're missing buckets that the migration expects
them to have.

We fix this by simply creating the buckets as we go, if needed.

channeldb/graph: dedup channel edges returned from ChanUpdatesInHorizon
In this commit, we ensure that we de-duplicate the set of channel edges
returned from ChanUpdatesInHorizon. Other subsystems within lnd use this
method to retrieve and send all the channels with updates within a time
series to network peers. However, since the method looks at the edge
update index, which can include up to two entries per edge for each
policy, it's possible that we'd send channel announcements and updates
twice, causing extra bandwidth.

In this commit, we ensure policies for edges we create in

that there are two entries per edge in the edge update index. Because of
this, the test will fail because ChanUpdatesInHorizon will return
duplicate channel edges due to looking at all the entries within the
edge update index. This will be addressed in a future commit to allow
the set of tests to pass once again.

channeldb: add migration to properly prune edge update index
In this commit, we introduce a migration to fix some of the recent
issues found w.r.t. the edge update index. The migration attempts to fix
two things:

1) Edge policies include an extra byte at the end due to reading an
extra byte for the node's public key from the serialized node info.

2) Properly prune all stale entries within the edge update index.

As a result of this migration, nodes will have a slightly smaller in
size channeldb. We will also no longer send stale edges to our peers in
response to their gossip queries, which should also fix the fetching
channel announcement for closed channels issue.

Due to entries within the edge update index having a nil value, the

that if we were unable to retrieve a value for a certain key that the
entry was non-existent, which is why the improper pruning bug was not
caught. Instead, we'll assert the number of entries to be the expected
value and populate a lookup map to determine whether the correct entries
exist within it.

channeldb/graph: properly determine old update timestamp for an edge
In this commit, we fix a lingering issue within the edge update index
where entries were not being properly pruned due to an incorrect
calculation of the offset of an edge's last update time. Since the
offset is being determined from the end to the start, we need to
subtract all the fields after an edge policy's last update time from the
total amount of bytes of the serialized edge policy to determine the
correct offset. This was also slightly off as the edge policy included
an extra byte, which has been fixed in the previous commit.

Instead of continuing the slicing approach however, we'll switch to
deserializing the raw bytes of an edge's policy to ensure this doesn't
happen in the future when/if the serialization methods change or extra
data is included.

time going backwards, we'd always be incorrect, causing us to not
properly prune the edge update index.
