channeldb: in RestoreChannelShells don't exit if edge already exists
During the restore process, it may be possible that we have already
heard about our prior edge from a node on the network (or our channel
peers). As a result, we shouldn't exit if this happens, and instead
should continue with the rest of the restoration process.

channeldb: within AddrsForNode don't fail if no graph node is found
In this commit, we modify the `AddrsForNode` method to not fail if no
graph node is found. We do this as when the backup is being
restored/created, it's possible that we don't yet have a
NodeAnnouncement for that node.

channeldb: set restored chan status within RestoreChannelShells
In this commit, we move the location where we restore the channel status
to within the `RestoreChannelShells` method itself. Before this commit,
we attempted to use `ApplyChanStatus` which creates a DB transaction and
relies on a fully populated channel state, which in the restoration
case, we don't yet have.

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.

channeldb: extend DeleteChannelEdge to mark edge as zombie
We mark the edges as zombies when pruning them to ensure we don't

have been removed from the graph due to being stale.

3555d3dbd4 channeldb: convert all Update calls to use Batch
In this commit, we convert all the `Update` calls which are serial, to
use `Batch` calls which are optimistically batched together for
concurrent writers. This should increase performance slightly during the
initial graph sync, and also updates at tip as we can coalesce more of
these individual transactions into a single transaction.

htlcswitch: hodl invoice
This commit modifies the invoice registry to handle invoices for which
the preimage is not known yet (hodl invoices). In that case, the
resolution channel passed in from links and resolvers is stored until we
either learn the preimage or want to cancel the htlc.

lnwallet: update TestChanSyncFailure to pass with new borked update restriction
In this commit, we update the `TestChanSyncFailure` method to pass given
the new behavior around updating borked channel states. In order to do
this, we add a new method to allow the test to clear an existing channel
state. This method may be of independent use in other areas in the
codebase in the future as well.

multi: make AddPreimage variadic, optimistically compute key
In this commit, we modify the WitnessCache's
AddPreimage method to accept a variadic number
of preimages. This enables callers to batch
preimage writes in performance critical areas
of the codebase, e.g. the htlcswitch.

Additionally, we lift the computation of the
witnesses' keys outside of the db transaction.
This saves us from having to do hashing inside
and blocking other callers, and limits extraneous
blocking at the call site.

channeldb: add gossiper message store key migration
In this commit, we introduce a migration for the message store
sub-bucket that will migrate all keys within it to a new key format.
This new key format is composed of the peer's public key, followed by
the short channel ID, followed by the message type. This migration is
needed in order to provide backwards-compatibility with messages that
were previously stored before the introduction of the new key format.

channeldb: add new RestoreChannelShells method
In this commit, we add a new type (ChannelShell) along with a new
method, RestoreChannelShells which allows a caller to insert a series of
channel shells into the database. These channel shells will allow a
restored node to initiate the DLP protocol and recover their set of
existing channels.

When we insert a channel shell, we re-create the original link node, and
also add the outgoing edge to the channel graph. This way we can be sure
that upon start up, we attempt to connect to the remote peers, and that
the normal graph query commands will operate as expected.

channeldb/channel: ignore ChannelEdgePolicy with missing max_htlc
If the max_htlc field is not found when fetching a ChannelEdgePolicy
from the DB, we treat this as an unknown policy.

This is done to ensure we won't propagate invalid data further. The data
will be overwritten with a valid one when we receive an update for this
channel.

It shouldn't be very common, but old data could be lingering in the DB
added before this field was validated.

multi: partition lnwire.ChanUpdateFlag into ChannelFlags and MessageFlags
In this commit:

* we partition lnwire.ChanUpdateFlag into two (ChanUpdateChanFlags and
ChanUpdateMsgFlags), from a uint16 to a pair of uint8's

* we rename the ChannelUpdate.Flags to ChannelFlags and add an
additional MessageFlags field, which will be used to indicate the
presence of the optional field HtlcMaximumMsat within the ChannelUpdate.

* we partition ChannelEdgePolicy.Flags into message and channel flags.
This change corresponds to the partitioning of the ChannelUpdate's Flags
field into MessageFlags and ChannelFlags.

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.

channeldb/invoices+test: don't return invoices on reversed query at index 1
Previously a call to QueryInvoices with reversed=true and index_offset=1
would make the cursor point to the first available invoice (num 1) that
would be returned as part of the response. This is inconsistent with the
othre indexes, so we instead just return an empty list in this case.

A test case for this situation is also added.

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.

rpcserver+lnrpc+lncli: add AbandonChannel rpc call
Using AbandonChannel, a channel can be abandoned. This means
removing all state without any on-chain or off-chain action.
A close summary is the only thing that is stored in the db after
abandoning.

A specific close type Abandoned is added. Abandoned channels
can be retrieved via the ClosedChannels RPC.

channeldb/migrations: improve performance of edge update migration
This commit modifies the edge update index
migration to avoid repetitive calls to
Cursor.First(). Instead, we construct a set
of all edge update keys to remove, and then do
a second pass to remove each from the bucket.
Additional log messages are included to notify
users on progress, as some have reported long
migration times.

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.
