channeldb: skip sub-buckets during invoice time series migration
In this commit, we fix an existing bu gin the invoice time series
migration code. Before this commit, the migration would fail as we would
try to migrate an empty invoice. We now detect this case and skip all
empty invoices.

We also add a bit more logging on both the info and trace logging level.

channeldb: add two methods to allow seeking into the invoice time series
In this commit, we add two new methods: InvoicesAddedSince and
InvoicesSettledSince. These methods will be used by higher level
sub-systems that implement notifications to deliver any notifications
backlog based on the last add index, and last settle index that the
client knows of.

It's important to note that care has been taken to ensure that this new
API can be used in a backwards compatible manner. If a client specifies
and index of 0 for either of the methods, then no backlog will be sent.
This is due to the fact that current users of the API don't expect any
backlog notifications to be sent. Additionally, the index actually
starts at 1, instead of 0.

channeldb: add new add+settle index to invoice database
In this commit, we add two new indexes to the invoice database: the add
index, and the settle index. These to indexes essentially form a time
series index on top of the existing primary index bucket. Each time an
invoice is added, we'll advance the addIndex seqno, and then create a
mapping from seqNo -> invoiceNum. Each time an invoice is settled, we'll
do the same, but within the settle index.

This change is required in order to allow callers to effectively seek
into the current invoice database in order to obtain notifications for
any invoices they may have missed out on while they were disconnected.
This will allow us to implement robust streaming invoice notifications
within lnd to ensure that clients never miss an event.

channeldb: add new AmtPaid field to the Invoice struct
In this commit, in order to allow the caller to specify the amount that
was ultimately accepted for an invoice, the SettleInvoice method has
gained a new parameter: amtPaid. SettleInvoice will now populate the
final amount paid in the database upon db commit.

8dcfeeaef5 channeldb: explicitly store the FinalCltvDelta within the ContractTerm struct
In this commit, we move to explicitly storing a bit more information
within the invoice. Currently this information is already stored in the
payment request, but by storing it at this level, callers that may not
be in the state to fully decode a payment request can obtain this data.

We avoid a database migration by appending this data to the end of an
invoice. When decoding, we'll try to read out this extra information,
and simply return what we have if it isn't found.

channeldb/waitingproof: improve external consistency of store
This commit synchronizes the in-memory cache with the
on-disk state to ensure the waiting proof store is
externally consistent. Currently, there are scenarios
where the in-memory state is updated, and not reverted
if the write fails. The general fix is to wait to apply
modifications until the write succeeds, and use a
read/write lock to synchronize access with db operations.

channeldb: ensure items from the update index are actually deleted
In this commit, we fix an existing bug in the new graph query sync
feature. Before this commit, when a block is pruned, we would never
actually delete the update index entries. This is due to the fact that
we would attempt to delete the entries from the update index _after_ we
had already removed the edges from the update index.

We fix this by simply swapping the order: first we delete from the
update index, then we delete the edges themselves. A test ensuring that
the entires are cleared (which failed before this commit), has been
added.

multi: ensure addresses are no longer assumed to be TCP addresses only
In this commit, we go through the codebase looking for TCP address
assumptions and modifying them to include the recently introduced onion
addresses. This enables us to fully support onion addresses within the

channeldb: don't reject duplicate waiting proofs
In this commit, we modify the waiting proof slightly to acept dupliacte
waiting proofs, rather than reject them. Otherwise, it's possible that
the remote node first sends us their half of the waiting proof (before
we do), we write that to disk, then upon restart, we'll try to add it
again, but be rejected by the system.

Fixes #1315.

channeldb: ensure that when we delete a channel we delete entry in edge update index
In this commit, we ensure that all indexes for a particular channel have
any relevant keys deleted once a channel is removed from the database.
Before this commit, if we pruned a channel due to closing, then its
entry in the channel update index would ever be removed.

channeldb: add database migration for new node+edge update indexes
In this commit, we add a new database migration required to update old
database to the version of the database that tracks the update index for
the nodes and edge policies. The migration is straight forward, we
simply need to populate the new indexes for the all the nodes, and then
all the edges.

channeldb: add new methods required to implement new discovery.ChannelGraphTimeSeries interface
In this commit, we add a series of methods, and a new database index
that we'll use to implement the new discovery.ChannelGraphTimeSeries
interface interface. The primary change is that we now maintain two new
indexes tracking the last update time for each node, and the last update
time for each edge. These two indexes allow us to implement the
NodeUpdatesInHorizon and ChanUpdatesInHorizon methods. The remaining
methods added simply utilize the existing database indexes to allow us to
respond to any peer gossip range queries.

A set of new unit tests has been added to exercise the added logic.

channeldb/channel: update IsPending godoc
The pending state definitin in ChannelCloseSummary was slightly changed
in such a way that channels that has had their commitment broadcasted
now is no longer considered "pending close". They now instead stay in
the open chan bucket with the ChanStatus "CommitmentBroadcasted" until
their commitment is confirmed. This commit updates the IsPending godoc
to reflect this.

channeldb: modify updateChanBucket to no longer auto-create buckets
In this commit, we modify the existing updateChanBucket function to no
longer auto-create buckets if they don't exist. We do this in order to
fix a class of bug that could arise wherein after a channel has actually
be closed (and the parent buckets removed) a method that mutates the
channel state is called, which then re-creates the relevant set of
buckets. As a result, subsequent calls to any RPCs which need to read
all the channels will fail as most of the fields won't actually be
populated.

After this commit, the fullSync method is the only one that's able to
create the full bucket hierarchy.

channeldb: additionally store static channel information in CloseChannelSummary
In this commit, we extend the CloseChannelSummary by also storing: the
current unrevoked revocation for the remote party, the next pending
unused revocation, and also the local channel config. We move to store
these as the provide an extra level of defense against bugs as we'll
always store information required to derive keys for any current and
prior states.

channeldb: add method for fetching channels waiting for closing tx
This commit adds a new method FetchWaitingCloseChannels to the database,
used for fetching OpenChannels that have a ChanStatus != Default. These
are channels that are borked, or have had a commitment broadcasted, and
is now waiting for it to confirm.

The fetchChannels method is rewritten to return channels exclusively
based on wheter they are pending or waitingClose.

channeldb/channel: add property ChanStatus in place of IsBorked to OpenChannel
This commit changes the bool `IsBorked` in OpenChannel to a `ChanStatus`
struct, of type ChannelStatus. This is used to indicated that a channel
that is technically still open, is either borked, or has had a
commitment broadcasted, but is not confirmed on-chain yet.

The ChannelStatus type has the value 1 for the status Borked, meaning it
is backwards compatible with the old database format.
