discovery: pass peer quit signal to ProcessQueryMsg
This commit passes the peer's quit signal to the
gossipSyncer when attempt to hand off gossip query
messages. This allows a rate-limited peer's read
handler to break out immediately, which would
otherwise remain stuck until the rate-limited
gossip syncer pulled the message.

discovery/gossiper: bypass main event loop for queries
This commit restructures the delivery of gossip
query related messages, such that they are delivered
directly to the gossip syncers. Gossip query rate
limiting was introduced in #1824 on a per-peer basis.
However, since all gossip query messages were being
delivered in the main event loop, the end result is
that one rate-limited peer could stall all other
peers.

In addition, since no other peers would be able to
submit gossip-related messages through the blocked
event loop, the back pressure would eventually rate
limit the read handlers of all peers as well.
The end result would be lengthy delays in reading
messages related to htlc forwarding.

The fix is to lift the delivery of gossip query
messages outside of the main event loop. With
this change, the rate limiting backpressure is
delivered only to the intended peer.

lnrpc: accept pubkey in hop message
By passing a pubkey into SendToRoute, it becomes unnecessary for lnd to
query the channel graph to retrieve the hop pubkey. This allows routes
over private channels that are not present in the graph.

chainntnfs: dispatch conf/spend notifications after blocks
In this commit, we alter the different ChainNotifier implementations to
dispatch confirmation and spend notifications after blocks. We do this
to ensure the external consistency of our registered clients.

chainntnfs/txnotifer: prevent dispatching notifications within ConnectTip
In this commit, we modify the TxNotifier's ConnectTip method to no
longer dispatch notifications to any clients who had a request fulfilled
within the height connected. Instead, it will queue the notifications
for dispatch and we add a new method NotifyHeight, which will actually
dispatch them. We do this to allow the users of the TxNotifier to be
more flexible when dispatching notifications.

chainntnfs/neutrinonotify: make filter update synchronous
In this commit, we modify the notifier to handle filter updates
synchronously. We do this to prevent race conditions between new block
notifications and filter updates. Otherwise, it's possible for a new
block to come in that should match our filter, but doesn't due to the
filter being updated after.

We also modify their order so that the filter is updated first. We do
this so we can immediately start watching for the event at tip while the
rescan is ongoing.

chainntnfs/txnotifier: commit height hint after rescan is complete
In this commit, we'll now commit the current height of the TxNotifier as
the height hint for an outpoint/transaction after a rescan has been
completed and has determined that the outpoint is unspent/transaction is
unconfirmed. We do this to prevent another potentially long rescan if
the daemon is restarted before a new block comes in (which is when the
hints will be updated again).

chainntnfs/neutrinonotify: handle spend notification registration w/ TxNotifier
In this commit, we modify the logic within RegisterSpendNtfn for the
NeutrinoNotifier to account for the recent changes made to the
TxNotifier. Since it is now able to handle spend notification
registration and dispatch, we can bypass all the current logic within
the NeutrinoNotifier and interact directly with the TxNotifier instead.

The most notable change is that now we'll only attempt a historical
rescan if the TxNotifier tells us so.

chainntnfs/txnotifier: correctly update confirm/spend hints on chain updates
In this commit, we address an issue w.r.t. updating the confirm hints
for transactions and spend hints for outpoints on chain updates.
Previously, upon a block being disconnected, we'd attempt to commit a
new height hint for all outstanding confirmation notifications. This is
not correct because we'll end up modifying the height hint for things
that have confirmed at a previous height than the one being
disconnected. This would cause issues on restart when attempting a
historical dispatch, as we would start scanning at a height above which
the transaction actually confirmed in.

This has been addressed by only updating the hints for outstanding
notifications that are still unconfirmed/unspent and for notifications
that were confirmed/spent within the block being connected/disconnected.

chainntnfs/txnotifier: detect reorgs for spending transactions of registered outpoints
In this commit, we introduce support to the TxNotifier to detect
spending transactions of registered outpoints being reorged out of the
chain. In the event that a reorg does occur, we'll consume the Spend
notification if it hasn't been consumed yet, and dispatch a Reorg
notification instead.

chainntnfs/txnotifier: watch for spends at tip
In this commit, we add support to allow the TxNotifier to properly

that spends a registered outpoint. In the event that it does, spend
notifications will be dispatched to all active registered clients for
such outpoint.

chainntnfs/txnotifier: allow registration of spend notifications
In this commit, we introduce the registration logic for spend
notifications to the TxNotifier. Most of this logic was taken from the
different existing ChainNotifier implementations, however, it features
some useful additions in order to make the ChainNotifier a bit more robust.

Some of these additions include the following:

  1. RegisterSpend will now return a HistoricalSpendDispatch struct,
  which includes the details for successfully determining if an outpoint
  was spent in the past. A HistoricalSpendDispatch will only be returned
  upon the first registration of an outpoint. This is done as,
  previously, if multiple clients registered for the same outpoint, then
  multiple historical rescans would also be dispatched, incurring a toll
  on the backend itself.

  2. UpdateSpendDetails will now be used to determine when a historical
  rescan has completed, no matter if a spending transaction was found or
  not. This is needed in order to responsibly update the spend hints for
  outpoints at tip, otherwise we'd attempt to update them even though we
  haven't yet determined if they have been spent or not. This will
  dispatch notifications to all currently registered clients for the
  same outpoint. In the event that another client registers later on,
  then the spending details are cached in memory in order to prevent
  further historical rescans.

chainntnfs: extend SpendEvent with reorg channel
In this commit, we add a new channel within the SpendEvent struct that
will be sent upon whenever the spending transaction of the registered
outpoint gets reorged out of the chain. This will pave the road for
successfully handling a funding transaction getting reorged out of the
chain among other things.
