routing/payment_lifecycle+channeldb: collect existing outcome first
To move towards how we will handle existing attempt in case of MPP
(collecting their outcome will be done in separate goroutines separate
from the payment loop), we move to collect their outcome first.

To easily fetch HTLCs that are still not resolved, we add the utility
method InFlightHTLCs to channeldb.MPPayment.

f757bf48bd channeldb: use RemoteCommitment in NextLocalHtlcIndex
This commit changes the fallback in NextLocalHtlcIndex to
RemoteCommitment since the LocalHtlcIndex field lags behind
on the LocalCommitment. Without this bug fix, open circuits
would get prematurely trimmed, resulting in more erroneous
logs. A test case is included to check that the fix works.

channeldb: add new frozen channel type bit and thaw height
In this commit, we add a new channel type bit: a frozen channel. A
frozen channel is one that can only be cooperatively closed by the
responder, but not the initiator. This channel type is useful for
certain classes of channel factory like protocols. We then add a new key
on the channel bucket level to store the height after which this
restriction no longer applies.

channeldb: add balance at height lookup
Add a balance at height lookup function which can be used to
obtain local/remote balance at a given height. The current in memory

build: silence new linter errors, tidy modules
The explicit `bbolt` dep is gone, as we depend on `kvdb`, which is
actually `walletdb`, which has its own module that defines the proper
`bbolt` version.

channeldb: convert to uniformly use new kvdb abstractions
In this commit, we migrate all the code in `channeldb` to only reference
the new `kvdb` package rather than `bbolt` directly.

In many instances, we need to add two version to fetch a bucket as both
read and write when needed. As an example, we add a new
`fetchChanBucketRw` function. This function is identical to
`fetchChanBucket`, but it will be used to fetch the main channel bucket
for all _write_ transactions. We need a new method as you can pass a
write transaction where a read is accepted, but not the other way around
due to the stronger typing of the new `kvdb` package.

channeldb/kvdb: create new package for an abstract kv store
In this commit, we create a new package `kvdb`, which is meant to serve
as the basis for any future database abstractions within `lnd`. Rather
than directly use the `walletdb` package (which we base off of), we
instead use a series of type-aliases to re-type the fundamental
types/interfaces of the `walletdb` package. This lets us type
`kvdb.RwTx` instead of `walletdb.ReadWriteTransaction` everywhere.
Additionally, our usage of type-aliases is also intended to create an
easy pathway in the future wherein we can gradually re-defined or
re-implement these types to wean off of the `walletdb` package.

channeldb/migration13: migrate to mpp structure
This commit migrates the payments in the database to a new structure
that allows for multiple htlcs per payments. The migration introduces a
new sub-bucket that contains a list of htlcs and moves the old single
htlc into that.

channeldb+routing: store full htlc failure reason
This commit extends the htlc fail info with the full failure reason that

channeldb+routing: store all payment htlcs
This commit converts the database structure of a payment so that it can
not just store the last htlc attempt, but all attempts that have been
made. This is a preparation for mpp sending.

In addition to that, we now also persist the fail time of an htlc. In a
later commit, the full failure reason will be added as well.

A key change is made to the control tower interface. Previously the
control tower wasn't aware of individual htlc outcomes. The payment
remained in-flight with the latest attempt recorded, but an outcome was
only set when the payment finished. With this commit, the outcome of
every htlc is expected by the control tower and recorded in the
database.

Add an optional channel status CloseChannel which will be stored on the
hitsorical channel which is persisted at channel close. This status is

funding flow or we abandon. In follow up commits, this status will be
used to record force and breach closes. The value is written to the
historical channel bucket for diplay over rpc.

channeldb: store close initiator status
This commit adds two new channel statuses which indicate the party that
initatited closing the channel. These statuses are set in conjunction
with the existing commit broadcast status so that we do not need to
migrate existing logic to handle multiple types of closes. This status
is set for locally initiated force closes in this commit because they
follow a similar pattern to cooparative closes, marking the commitment
broadcast then proceeding with tx broadcast. Remote force closes are
added in the following commit, as they are handled differently.

channeldb: update payment request comment
This field isn't optional. It was introduced in
5ed31b1030176374d4184fee0b80ae7679e0e355 which was part of release
0.4.0. This release contained breaking database changes, so it is safe
to assume that from there on the field is always populated.

If there would still be empty payment request fields in the wild, users
would also experience issues with ListInvoices. ListInvoices decodes the
payment request.

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).

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

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
