htlcswitch: hodl invoice
This commit modifies the invoice registry to handle invoices for which
the preimage is not known yet (hodl invoices). In that case, the
resolution channel passed in from links and resolvers is stored until we
either learn the preimage or want to cancel the htlc.

htlcswitch: abtract invoice from link
This commit detaches signaling the invoice registry that an htlc was
locked in from the actually settling of the htlc.

It is a preparation for hodl invoices.

htlcswitch/test: use real invoice registry with temp db as mock
In further commits the behaviour of invoice registry becomes more
intrinsically connected to the link. This commit prepares for that by
allowing link and registry to be tested as a single unit.

htlcswitch/test: make unknown hash test independent of mock
In the TestChannelLinkMultiHopUnknownPaymentHash test, a preimage was
modified to trigger an unknown payment hash failure. The way the mock is
implemented, it would take the hash of that modified preimage and store
it. It basically stores a completely different invoice. For this test,
it is just as good to store no invoice at all.

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.

htlcswitch: resolve invoice cancelation race condition
Previously it could happen that an invoice was open at the time of the
LookupInvoice call, the htlc was settled because of that, but when the
SettleInvoice call was made eventually, it would fail because the
invoice was canceled in the mean time. The htlc would then be settled,
but the invoice not marked as such.

contractcourt: add access to full invoice registry from resolvers
Previously a function pointer was passed to chain arbitrator to avoid a
circular dependency. Now that the routetypes package exists, we can pass
the full invoice registry to chain arbitrator.

This is a preparation to be able to use other invoice registry methods
in contract resolvers.

autopilot/agent: distribute available funds among channels
This commit fixes a regression in how we allocate funds to attempted
channels. We would earlier stay within the channel size limits, but we
wouldn't account for funds consumed by other channels being opened in
parallel.

We fix this by introducing a loop which greadily tries to distribute the
funds among the channels to open, and reduces the number of channels to
open in case not enough funds are available to satisfy the channel size
limits.

multi: remove ErrDoubleSpend check for PublishTransaction
In this commit, we address a lingering issue within some subsystems that
are responsible for broadcasting transactions. Previously,
ErrDoubleSpend indicated that a transaction was already included in the
mempool/chain. This error was then modified to actually be returned for
conflicting transactions, but its callers were not modified accordingly.
This would lead to conflicting transactions to be interpreted as valid,
when they shouldn't be.

lnwallet/btcwallet: remove unnecessary tx in mempool/chain checks
The checks to determine whether the transaction broadcast failed due to
it already existing in the mempool/chain are no longer needed since the
underlying btcwallet PublishTransaction call will not return an error
when running into these cases.

contractcourt: fix off-by-one error in closeObserver case
In this commit, we fix an off-by-one error when handling force closes
from the remote party. Before this commit, if the remote party
broadcasts state 2, and we were on state 1, then we wouldn't act at all.
This is due to an extraneous +1 in the comparison, causing us to only
detect this DLP case if the remote party's state is two beyond what we
know atm. Before this commit, the test added in the prior commit failed.

contractcourt: add new TestChainWatcherDataLossProtect test case
In this commit, we add a new test case to exercise the way we handle the
DLP detection and dispatch within the chain watcher. Briefly, we use
the `testing/quick` package to ensure that the following invariant is
always held: "if we do N state updates, then state M is broadcast, iff M
> N, we'll execute the DLP protocol". We limit the number of iterations
to 10 for now, as the tests can take a bit of time to execute, since it
actually does proper state transitions.

contractcourt: abstract call to GetStateNumHint within the closeObserver
In this commit, we abstract the call to `GetStateNumHint` within the
`closeObserver` method to a function closure in the primary config. This
allows us to feed in an arbitrary broadcast state number within unit
tests.

1fe6599fd8 lnd+chainregistry: initialize neutrino light client before wallet setup
In this commit, we slightly refactor the startup of lnd when running
with a Neutrino light client backend. We'll now begin syncing our
backend as soon as lnd starts and passes all configuration checks. Since
this is all done before lnd's wallet setup, the light client will be
syncing in the background while the user notes/inputs their wallet seed.
This is done in order to provide a better UX from the point of the user,
such that most of the chain will already be synced by the time they get
to deposit funds into the wallet.

In this commit, we update the build to point to the latest version of

latest version of btcwallet contains a number of bug fixes related to
properly remove invalid transactions from its database.

routerrpc: move query routes into sub server
This commit moves the query routes backend logic from the main
rpc server into the sub server. It is another step towards splitting up
the main rpc server code.

In addition to this, a unit test is added to verify rpc parameter
parsing.

lnwallet: update TestChanSyncFailure to pass with new borked update restriction
In this commit, we update the `TestChanSyncFailure` method to pass given
the new behavior around updating borked channel states. In order to do
this, we add a new method to allow the test to clear an existing channel
state. This method may be of independent use in other areas in the
codebase in the future as well.

contractcourt: mark channel as borked before removing the link
In this commit, we ensure that we mark the channel as borked before we
remove the link during the force close process. This ensures that if the
peer reconnects right after we remove the link, then it won't be loaded
into memory in `loadActiveChannels`. We'll now:

  * mark the channel as borked
  * remove the link
  * read the channel state from disk
  * force close

This ensures that the link (if it's active) is able to commit any
pending changes to disk before we read out the channel to force close.
