channeldb: add zombie edge index
In this commit, we add a zombie edge index to the database. This allows
us to quickly determine across restarts whether we're attempting to
process an edge we've previously deemed as zombie.

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: add prefix naming to ChannelStatus enum variables
In this commit, we add a prefix naming scheme to the ChannelStatus enum
variables. We do this as it enables outside callers to more easily
identify each individual enum variable as a part of the greater
enum-like type.

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.

channeldb: fix bucket creation hierarchy in createChannelDB
In this commit, we fix a bug in the bucket creation code in
createChannelDB. This bug can cause migrations on older nodes to fail,
as we expect the bucket to already have been created. With this commit,
we ensure that all the buckets under the main node and edges bucket are
properly created. Otherwise, a set of the newer migrations will fail to
apply for nodes updating from 0.4.

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.

6c918a1806 channeldb: store unknown policies in database
The commit ensures that for every channel, there will always
be two entries in the edges bucket. If the policy from one or
both ends of the channel is unknown, it is marked as such.

This allows efficient lookup of incoming edges. This is
required for backwards payment path finding.

channeldb+server: prune link nodes on startup
In this commit, we extend the server's functionality to prune link nodes
on startup. Since we currently only decide whether to prune a link node
from the database based on a channel close, it's possible that we have
link nodes lingering from before this functionality was added on.

channeldb: add new migration to finalize invoice migration for outgoing payments
In this commit, we migrate the database away from a partially migrated
state. In a prior commit, we migrated the database in order to update
the Invoice struct with three new fields: add index, settle index, paid
amt.  However, it was overlooked that the OutgoingPayment struct also
embedded an Invoice within it. As a result, nodes that upgraded to the
first migration found themselves unable to start up, or call
listpayments, as the internal invoice within the OutgoignPayment hadn't
yet been updated.  This would result in an OOM typically as we went to
allocate a slice with a integer that should have been small, but may
have ended up actually being a set of random bytes, so a very large
number.

In this commit, we finish the DB migration by also migrating the
internal invoice within each OutgoingPayment.

Fixes #1538.
Fixes #1546.

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 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/db: adds FetchClosedChannel
This commit adds a FetchClosedChannel method to the
channeldb, which allows querying based on a known
channel point. This will be used in the nursery to
load channel close summaries, which can be used to
provide more accurate height hints when recovering
from failures.

This commit modifies the OpenChannel struct to include the full short

This commit expands the field within the OpenChannel struct in order to
start tracking the height that the funding transaction was initially

more accurate height hint to the ChainNotifier, or to use during the
funding workflow to decide if a channel should be forgotten after it
fails to confirm for N blocks.

channeldb: add new method to db, MarkChanFullyClosed
This commit adds a new method to the database which allows callers to
mark a channel as fully closed once certain conditions have been
reached. If a channel was cooperatively closed, then it can be marked
as fully closed as soon as the channel has been confirmed. If the
channel was marked as force closed, then it should be marked as closed
as soon as _all_ the funds in limbo have been swept.
