channeldb+invoices: make htlc cancelation stricter
Previously it was possible to cancel a canceled htlc. This would
subtract the htlc amount from the invoice amount again.

channeldb/test: make route comparison a pure function

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.

7300f33fe2 graph: implement index for disabled channels.
This commit adds an index bucket, disabledEdgePolicyBucket, for those
ChannelEdgePolicy with disabled bit on.
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

61a1ab08fb routing+channeldb: findPath uses Vertex instead of LightningNode
This commit modifies the nodeWithDist struct to use a route.Vertex
instead of a *channeldb.LightningNode. This change, coupled with
the new ForEachNodeChannel function, allows the findPath Djikstra's
algorithm to cut down on database lookups since we no longer need
to call the FetchOtherNode function.

channeldb/migrations: skip migration for empty outgoing payments bucket
Previously the migration would fail if the source node was not set in
the database. Since we know that the source node must have been set
before making any payments, we check whether there actually are any
payments to migrate, and return early if not.
