discovery: set GossipSyncer update horizon to current time
With the introduction of the gossip sync manager in a later commit,
retrieving the backlog of updates within the last hour is no longer
necessary as we'll be forcing full syncs periodically.

discovery: replace GossipSyncer syncChanUpdates flag with SyncerType
In this commit, we introduce a new type: SyncerType. This type denotes
the type of sync a GossipSyncer is currently under. We only introduce
the two possible entry states, ActiveSync and PassiveSync. An ActiveSync
GossipSyncer will exchange channels with the remote peer and receive new
graph updates from them, while a PassiveSync GossipSyncer will not and
will only response to the remote peer's queries.

This commit does not modify the behavior and is only meant to be a
refactor.

signal: don't attempt to catch SIGSTOP
In this commit, we modify the set of default signals we attempt to catch in
order to execute a graceful shutdown. Before this commit, we would attempt
to catch/register for `SIGSTOP`. There're two issues with this

  1. `SIGSTOP` is meant to be used in combination with `SIGCONCT` to allow a
  process to be paused/resumed. Therefore, our action of shutting down once
  received was incorrect.

  2. `SIGSTOP` doesn't exist on windows, so users aren't able to compile on
  this platform without modifying the codebase.

chainntnfs/bitcoindnotify: always call UpdateSpendDetails
This commit fixes a bug that would cause the
notifier not to commit spend hints for items
that are not found. This is done by calling
UpdateSpendDetails with a nil detail, permitting
the notifier to begin updating the spend hints
with new blocks that arrive at tip. The change
is designed to mimic the behavior for historical
confirmation dispatch.

The symptom of this bug is needing to do many
long rescans on startup, even if new blocks
arrive after the rescan had completed. With
this change, nodes will have to do the scans
once more before their hints will be properly
updated. Restarts from then on should not
have this behavior.

lncfg/interface: define Validator iface + variadic Validate
This commit introduces the Validator interface, which
is intended to be implemented by any sub configs. It
specifies a Validate() error method that should fail
if a sub configuration contains any invalid or insane
parameters.

In addition, a package-level Validate method can be
used to check a variadic number of sub configs
implementing the Validator interface. This allows the
primary config struct to be extended via targeted
and/or specialized sub configs, and validate all of
them in sequence without bloating the main package
with the actual validation logic.

test: add new series of itests for various SCB restore scenarios
In this commit, we add 4 new itests for exercising the SCB restore
process via 4 primary scenarios: recover from backup using RPC, recover
from file using RPC, recover channels during init/creation, recover
channels during unlock. With all fields populated there're a total of 24
new scenarios to cover. At the time of authoring of this commit, the
other scenarios (bits are: initiator, updates, private) have been left
out for now, as they increased the run time of the integration tests
significantly.

test: refactor testDataLossProtection to extract core DLP scenario out to new func
In this commit, we modify the core testDataLossProtection test to
extract the primary DLP assertion logic into a new function. We do this,
as the upcoming SCB tests will fallback to this test after some initial
set up.

lntest: extend the restore/restart methods to also accept optional SCBs
In this commit, we modify the `RestoreNodeWithSeed` and `RestartNode`
methods to also accept an SCB. This will be useful in new integration
tests to properly exercise the various restore/restart scenarios using
static channel backups.

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.

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.

contractcourt: ignore all other dispatch cases in closeObserver when recovered chan
In this commit, we modify the `closeObserver` to fast path the DLP
dispatch case if we detect that the channel has been restored. We do
this as otherwise, we may inadvertently enter one of the other cases
erroneously, causing us to now properly look up their dlp commitment
point.

contractcourt: only look for local force close for non-recovered channel
In this commit, we modify the main `closeObserver` dispatch loop to only
look for the local force close if we didn't recover the channel. We do
this, as for a recovered channel, it isn't possible for us to force
close from a recovered channel.
