server: use nil errChan for broadcasts
This skips creating errChans when sending messages to
peer during broadcast. This should be a minor memory
optimization, as well as not requiring channel sends
on those which will never be read.

server: reliably hand off breach from the ChainArbitrator to the breachArb
This commit make the server populate the ChainArbitrator's
ContractBreach method, by a method that will reliably handoff the breach
event ot the breachArbiter. The server will now forward the breach event
to the breachArbiter, and only let the closure return a non-nil error
when the breachArbiter ACKs this event.

server: don't directly mutate net.TCPAddr for inbound connections to set peer port
In this commit, we fix a minor logging bug introduced in a prior commit.
Before we would directly modify the *net.TCPAddr that was a part of the
brontide connection. This achieved our goal, but would print weird log
messages as we mutated the port in the already established connection.

In this commit, we fix that by ensuring we create a copy iff it's a
net.TCPAddr, then modify that and replace the instance in the
lnwire.NetAddress.

Fixes #991.

server: cleanup persistent connection retries
This commits changes the behavior of our connection
reestablishment, and resolves some minor issues that
could lead to uncancelled requests or an infinite
connection loop.

 - Will not attempt to Remove connection requests with
   an ID of 0. This can happen for reconnect attempts
   that get scheduled, but have not started at the
   time the server cancels the connection requests.

 - Adds a per-peer cancellation channel, that is
   closed upon a successful inbound or outbound
   connection. The goroutine spwaned to handle the
   reconnect by the peerTerminationWatch now
   selects on this channel, and skips reconnecting
   if it is closed before the backoff matures.

 - Properly computes the backoff when no entry in
   persistentPeersBackoff is found. Previously, a
   value of 0 would be returned, cause all subsequent
   backoff attempts to use a backoff of 0.

 - Cancels a peers retries and remove connections
   immediately after receiving an inbound connection,
   to mimic the structure of OutboundPeerConnected.

 - Cancels all persistent connection requests after
   calling DisconnectPeers.

 - Allow additional connection attempts to peers, even if
   there already exists a pending connection attempt.

server: when constructing peer addr's attempt to locate proper port, fallback to default port
In this commit, we fix an existing bug within the codebase: if a peer
connected to us inbound, then we'd attempt to use the assigned port when
re-establishing a connection to them. We fix this issue in this commit
by adding a new method to look up any advertisements for the peer, and
use the specified port that matches our connection attempt. If we can't
find a proper advertisement, then we'll simply use the default peer
port.

lnd can connect to it. When this flag is set, ALL traffic gets
routed over Tor including DNS traffic. Special functions for
DNS lookups were added, and since Tor doesn't natively support
SRV requests, the proxySRV function routes connects us to
a DNS server via Tor and SRV requests can be issued directly
to the DNS server.

server: improve server contention around mutex
This commit aims to reduce the contention on the server's primary
mutex by (1) replacing it with a RWMutex, and (2) not holding an
exclusive lock throughout the duration of the SendToPeer method.

For the latter, we now only have to hold a shared lock until all
messages have been queued, where as before an exclusive lock
was held until all messages had been acknowledged by the target
peer's write handler. Since the initial syncing of announcements
with peer now comprises a couple thousand messages on testnet,
these changes should help keep the server from deadlocking while
completing and long-lived syncing operations.

contractcourt: make synchronous chain watcher notifications optional
In this commit, we modify the way that notifications are dispatched
within the chainWatcher. Before we would *always* wait for an ack back
before we started to clean up he database state. This would at times
lead to deadlocks. To remedy this, we now allow callers to decide if
they want notifications to be sync or not. The only current caller that
requires this is the breach arbiter.

breacharbiter: utilize new channel on-chain event stream to watch for breaches
In this commit, we modify the breach arbiter to no longer require
holding a channel object directly in order to receive new notifications
about possible breaches. Instead, we’ll contact the chain arbiter to
request a new channel event subscription.

As a result of the new architecture, we no longer need to receive a
handoff once the new channel comes online, as the chainWatcher will
always be active and watching the channel until it’s been closed.

000a83bc04 server: add bootstrap peers to persistent peers for conn retry
Peers are treated as transient by default. When a peer is disconnected,
no attempt is made to reconnect. However, if we have a channel open
with a peer that peer will be added as persistent. If a persistent peer
becomes disconnected then we will attempt to reconnect.

This behavior implies that a fresh node - those without any channels -
will fall off the network over time as remote nodes restart or due to
connectivity changes. This change marks bootstrap peers as persistent
and ensures that the node remains connected to those specific peers over
time. This does not keep the node connected in the case that all
bootstrap peers are down.

Fixes #451.

server: Broadcast now takes a set of peers to skip
In this commit, we modify the Broadcast to take a *set* of peers to
skip, rather than just a single peer. We make this modification as when
a new channel is discovered, it’s likely the case that we get the
announcement from several peers rather than a single peer. With this
change, we’ll ensure that the caller (who is aware of the set of
senders) is able to properly avoid wasting bandwidth by re-sending the
message to all peers that sent it to us originally.

This commit fixes a deadlock that could occur when

This fixes that by also checking for peer shutdown.

server+funding: fix bug where funding tx could have zero fees attached
In this commit, we fix an existing bug that would cause funding
transaction to be broadcast without any fees attached at all. This is
only an issue if the fee rate reported is extremely so, as can happen
on testnet. In this case, when we went to scale down to sat/weight, we
would return a value of zero due to integer division. If we went via
the EstimateFeePerWeight call directly, then it would've been detected.
However, we accept the fee/byte from the user directly on the command
line this wasn't being done.

To fix this, we'll now manually set the fee to a sane value, if it
returns a value that can't properly be scaled to fee/weight.

funding+server: ensure we cancel all reservations when a peer disconnects
In this commit, we fix an existing issue that could at times cause an
inconsistent view between the set of total coins, and the set of segwit
coins in the wallet of the node. This could be caused by initiating a
funding flow, but then the funding negotiation breaking down somewhere
along the lines. In this case, us or the other peer will disconnect.
When we initiate funding flows, we lock coins exclusively, to ensure
that concurrent funding flows don’t end up double spending the same
coin. Before this commit, we wouldn’t ever unlock those coins. As a
result, our view of available coins would be skewed.

The walletbalance call would show all the coins, but when adding the
—witness_only flag, some coins would be missing, or gone all together.
This is because the former call actually scans the txstore and manually
tallies the amount of available coins, while the latter looks at the
sent of available outputs, which is filtered based on which coins are
locked.

To remedy this, we now ensure that when a peer disconnects, we wipe all
existing reservations which will return any locked outputs to the set
of available outputs for funding flows.

server: make sendToPeer async
This commit removes another case of unnecessary blockage, by modifying
the sendToPeer method to be fully asynchronous. From the PoV of the
callers that utilize this method currently, there’s no reason to block
until the completion of this method. Additionally, as the graph grows
larger without more intelligent the number of messages sent during
initial dump will start to be prohibitive to waiting for full
completion before proceeding.

server: BroadcastMessage will no longer block until completion
In this commit, we make the BroadcastMessage method on the server more
asynchronous by abandoning the two wait groups that it used for
synchronization. It has been observed that a circular waiting loop
between the AuthenticatedGossiper and a peer’s readHandler can cause
the system to dead lock.

By removing this unnecessary synchronization, we avoid the deadlock
case and allow the gossiper itself to no longer block in this scenario.

routing: implement 2-week zombie channel pruning
This commit implements 2-week zombie channel pruning. This means that
every GraphPruneInterval (currently set to one hour), we’ll scan the
channel graph, marking any channels which haven’t had *both* edges
updated in 2 weeks as a “zombie”. During the second pass, all “zombie”
channel are removed from the channel graph all together.

Adding this functionality means we’ll ensure that we maintain a
“healthy” network view, which will cut down on the number of failed
HTLC routing attempts, and also reflect an active portion of the graph.

server: fix logging statement in peerBootstrapper
This commit fixes an incorrect logging statement within the
peerBootstrapper goroutine. We we’re using a Debug method previously
when we should’ve been using Debugf in order to properly pass the
logging statement through.

server: add NotifyWhenOnline method.
This commit adds a listener queue for each peer, that can be used
to queue listeners that will be notified when the targetted peer
eventually comes online.

server: introduce new peerBootstrapper goroutine to seed initial conns
This commit adds a new primary goroutine to the server struct:
peerBootstrapper. If peer boostrapping isn’t disabled in the config,
this new goroutine will be launched to attempt to establish a set of
initial connections for a new node. The logic is pretty straight
forward: first a set of initial connections is attempted, if after our
first epoch, we don’t have enough connections yet, then we’ll attempt
to query for an additional set. In each iteration, if we haven’t been
successful, then we increase our exponential backoff in order to not
spam any of our bootstrapping sources.

91d6b0492e server: refactors w/ single mutex and sync disconnect
This commit alters the synchronization patterns used in the server
  such that the internal state is protected by a single mutex.  Overall,
  this simplifies the ability to reason about the behavior and
  manipulation of the internal state, which has resolved a few of flakes
  related to race conditions that were observed before hand.

  Invoking DisconnectPeer is now fully synchronous, and waits until
  the provided peer's peerTerminationWatcher has exited before
  returning.  Currently this is done by tracking the watcher using the
  peer's WaitGroup, and locking until the peer has shutdown.

  The server's API has also been refactored such that all public methods
  are safe for concurrent use. Therefore, other subsystems should be
  sure to make use of these endpoints to avoid corrupting the internal
  state.
