fundingmanager: populate additional edge info after adding to graph
This commit serves as another stop-gap for light clients since they are
unable to obtain the capacity and channel point of graph edges. Since
they're aware of these things for their own channels, they can populate
the information within the graph themselves once each channel has been
successfully added to the graph.

cnct: define separate broadcast delta for outgoing htlcs
This commits exposes the various parameters around going to chain and
accepting htlcs in a clear way.

In addition to this, it reverts those parameters to what they were
before the merge of commit d1076271456bdab1625ea6b52b93ca3e1bd9aed9.

server: stagger initial reconnects
This commit adds optional jitter to our initial reconnection to our
persistent peers. Currently we will attempt reconnections to all peers
simultaneously, which results in large amount of contention as the
number of channels a node has grows.

We resolve this by adding a randomized delay between 0 and 30 seconds
for all persistent peers. This spreads out the load and contention to
resources such as the database, read/write pools, and memory
allocations. On my node, this allows to start up with about 80% of the
memory burst compared to the all-at-once approach.

This also has a second-order effect in better distributing messages sent
at constant intervals, such as pings. This reduces the concurrent jobs
submitted to the read and write pools at any given time, resulting in
better reuse of read/write buffers and fewer bursty allocation and
garbage collection cycles.

server: convert Start/Stop methods to use sync.Once
In this commit, we convert the server's Start/Stop methods to use the
sync.Once. We do this in order to fix concurrency issues that would
allow certain queries to be sent to the server before it has actually
fully start up. Before this commit, we would set started to 1 at the
very top of the method, allowing certain queries to pass before the rest
of the daemon was had started up.

In order to fix this issue, we've converted the server to using a
sync.Once, and two new atomic variables for clients to query to see if
the server has fully started up, or is in the process of stopping.

link: increase expiry grace delta
This commit increase the expiry grace delta to a value above the
broadcast delta. This prevents htlcs from being accepted that would
immediately trigger a channel force close.

A correct delta is generated in server.go where there is access to
the broadcast delta and passed via the peer to the links.

invoices: extract invoice decoding from registry
Previously it was difficult to use the invoice registry in unit tests,
because it used zpay32 to decode the invoice. For that to succeed, a
valid signature is required on the payment request.

This commit injects the decode dependency on a different level so that
it is easier to mock.

6c256aea30 server: fix the algo to prefer connections when multiple exist
This commit modified the condition to whether drop an existing
connection to a peer when a new connection to this peer is
established.
The previous algorithm used public keys comparison for this decision
which determines that between every two nodes only one of them will
ever drop the connection in such cases.
The problematic case is when a node disconnects and reconnects in a
short interval which is the case of mobile devices.
In such case it takes as much as the "timeout" configured value for
the remote node to detect the "disconnection" (and try to reconnect
if this connection is persistent). In the case this node is also the
one that has the "smaller" public key the reconnect attempts of the
other node will be rejected causing it impossible to fast reconnect.

The solution is to only drop the connection if if we already have a
connected peer that is of the opposite direction from the this new
connection. By doing so the "initiator" will be enabled to replace
the connection and recconnect immediately.

cb26fd8a17 lnd: introduce the ChannelNotifier.
This commit introduces the channel notifier which is a central source
of active, inactive, and closed channel events.

This notifier was originally intended to be used by the `SubscribeChannels`
streaming RPC call, but can be used by any subsystem that needs to be
notified on a channel becoming active, inactive or closed.

It may also be extended in the future to support other types of notifications.

server: use chanInfo instead of chanPolicy to establish channel peer conns
In this commit, we modify the way we attempt to locate the our channel
peer to establish a persistent connection on start up. Before this
commit, we would use the channel policy pointing to the peer to locate
the node as it's embedded in the struct. However, at times it's
currently possible for the channel policy to not be found in the
database if the remote nodes announces before we finalize the process on
our end. This can at times lead to a panic as the pointer isn't checked
before attempting to access it.

To remedy this, we now instead use the channel info which will _always_
be there if the channel is known.

* we partition lnwire.ChanUpdateFlag into two (ChanUpdateChanFlags and

* 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.

server: require the DLP bit for all incoming/outgoing connections
In this commit, we modify our default local feature bits to require the
Data Loss Protection (DLP) feature to be active. Once full Static
Channel Backups are implemented, if we connect to a peer that doesn't
follow the DLP protocol, then the SCBs are useless, as we may not be
able to recover funds. As a result, in prep for full SCB deployment,
we'll now ensure that any peer we connect to, knows of the DLP bit. This
could be a bit more relaxed and allow _connections_ to non-DLP peers,
but reject channel requests to/from them. However, this implementation is
much simpler.

multi: replace per channel sigPool with global daemon level sigPool
In this commit, we remove the per channel `sigPool` within the
`lnwallet.LightningChannel` struct. With this change, we ensure that as
the number of channels grows, the number of gouroutines idling in the
sigPool stays constant. It's the case that currently on the daemon, most
channels are likely inactive, with only a hand full actually
consistently carrying out channel updates. As a result, this change
should reduce the amount of idle CPU usage, as we have less active
goroutines in select loops.

In order to make this change, the `SigPool` itself has been publicly
exported such that outside callers can make a `SigPool` and pass it into
newly created channels. Since the sig pool now lives outside the
channel, we were also able to do away with the Stop() method on the
channel all together.

Finally, the server is the sub-system that is currently responsible for
managing the `SigPool` within lnd.

multi: modify sweeper.CreateSweepTx to accept conf target, style changes
In this commit, we modify the newly introduced UtxoSweeper.CreateSweepTx
to accept the confirmation target as a param of the method rather than a
struct level variable. We do this as this allows each caller to decide
at sweep time, what the fee rate should be, rather than using a global
value that is meant to work in all scenarios. For example, anytime
we're sweeping an output with a CLTV lock that's has a dependant
transaction we need to sweep/cancel, we may require a higher fee rate
than a regular force close with a CSV output.

In this commit IncubateOutputs are given an extra parameter
broadcastHeight, which is passed from the server and used when called
registerPresschoolConf.

Earlier the utxonursery used the bestHeight as height hint in this case,
which would be wrong in the cases where we got outputs for incubation
which was confirmed below the best height.

server: start tor controller if we should listen for inbound connections
over Tor

In this commit, we fix a small bug where we would attempt to start the
Tor controller even if we were not requested to automatically create and
onion service in order to listen for inbound connections over Tor.

server: ensure persistent connections to tor addrs are made if active
In this commit, we restrict the persistent connection logic on startup
to only attempt to establish connections to Tor addresses if Tor
outbound support is enabled. Otherwise, we'll continually attempt to
reach the address even though we never will.
