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.

3ee4f5fbd4 docs/docker: fixed link to /docker/README.md
Link must be /docker/README.md, relative to the repository's root. Previously it was relative to /docs, resulting in 404.

fundingmanager: hold mutex during ctx cancellation
This commit changes cancelReservationCtx to gold the resMtx from start
to finish. Earlier it would lock at different times only when accessing
the maps, meaning that other goroutines (I'm looking at you
PeerTerminationWatcher) could come in and grab the context in between
locks, possibly leading to a race.

fundingmanager: send on resCtx.err in failFundingFlow
This commit moves the responsibility of sending a funding error on the

need to keep track of sending it.

fundingmanager: send error directly in CancelPeerReservations
The error channel should never be nil, and it should always be buffered.
Because of this we can send directly on the channel.

discovery: if unable to find gossipSyncer for peer, create one
In this commit we fix an existing bug caused by a scheduling race
condition. We'll now ensure that if we get a gossip message from a peer
before we create an instance for it, then we create one on the spot so
we can service the message. Before this commit, we would drop the first
message, and therefore never sync up with the peer at all, causing them
to miss channel announcements.

discovery: attempt to request the full chan ann for stray chan updates
In this commit, we extend the AuthenticatedGossiper to take advantage of
the new query features in the case that it gets a channel update w/o
first receiving the full channel announcement. If this happens, we'll
attempt to find a syncer that's fully synced, and request the channel
announcement from it.

discovery: add new SyncState method to gossipSyncer
This new method allows outside callers to sample the current state of

we now only modify the g.state variable atomically.

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.

config: add new command line option to disable chan update all together
In this commit, we add a new command line option to allow (ideally
routing nodes) to disable receiving up-to-date channel updates all
together. This may be desired as it'll allow routing nodes to save on
bandwidth as they don't need the channel updates to passively forward
HTLCs. In the scenario that they _do_ want to update their routing
policies, the first failed HTLC due to policy inconsistency will then
allow the routing node to propagate the new update to potential nodes
trying to route through it.

In this commit, we create a new concrete implementation for the new
discovery.ChannelGraphTimeSeries interface. We also export the

structs.

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.

discovery: update AuthenticatedGossiper to be aware of new gossipSyncers
In this commit, we update the logic in the AuthenticatedGossiper to
ensure that can properly create, manage, and dispatch messages to any
gossipSyncer instances created by the server.

With this set of changes, the gossip now has complete knowledge of the
current set of peers we're conneted to that support the new range
queries. Upon initial connect, InitSyncState will be called by the
server if the new peer understands the set of gossip queries. This will
then create a new spot in the peerSyncers map for the new syncer. For
each new gossip query message, we'll then attempt to dispatch the
message directly to the gossip syncer. When the peer has disconnected,
we then expect the server to call the PruneSyncState method which will
allow us to free up the resources.

Finally, when we go to broadcast messages, we'll send the messages
directly to the peers that have gossipSyncer instances active, so they
can properly be filtered out. For those that don't we'll broadcast
directly, ensuring we skip *all* peers that have an active gossip
syncer.

discovery: add new gossipSyncer struct to manage sync state for each peer
In this commit, introduce a new struct, the gossipSyncer. The role of
this struct is to encapsulate the state machine required to implement
the new gossip query range feature recently added to the spec. With this
change, each peer that knows of this new feature will have a new
goroutine that will be managed by the gossiper.

Once created and started, the gossipSyncer will start to progress
through each possible state, finally ending at the chansSynced stage. In
this stage, it has synchronized state with the remote peer, and is
simply awaiting any new messages from the gossiper to send directly to
the peer. Each message will only be sent if the remote peer actually has
a set update horizon, and the message isn't before or after that
horizon.

A set of unit tests has been added to ensure that two state machines
properly terminate and synchronize channel state.

htlcswitch/decayedlog_test: create unique test dbs
This commit changes the decayed log tests to create

instances referenced the same db path. Since the tests
are run in parallel, the tests would create/delete the
shared db out from under each other, causing flakes in
