multi: add reset closure to kvdb.View
This commit adds a reset() closure to the kvdb.View function which will
be called before each retry (including the first) of the view
transaction. The reset() closure can be used to reset external state
(eg slices or maps) where the view closure puts intermediate results.

txnotifier test: add test for confirmation after cancellation
This test addition would cause the txnotifier to crash prior to the

txnotifier: delete ntfn by confirm height always
When we cancel a confirmation request, we should remove the request from
the height map regardless of the current height. Otherwise we end up in
the situation when the height is reached, the notification is attempted
sent which results in a crash.

chainntnfs/txnotifier: remove events on teardown
If a concurrent call to cancel is made while the notifier is shutting
down, this would cause a panic (close of closed channel) since the
events are not removed from the notification sets.

detected as included in a block and before its confirmation notification

ae2c37e043 Ensure chain notifier is started before accessed.
The use case comes from the RPC layer that is ready before the
chain notifier which is used in the sub server.

ceb454aa16 neutrinonotify: use batch for historical confirmations.
This commit introduces an optimization for the chain scanning
used in historical confirmations notifications.
It now uses batch request instead of requesting filters one by one.

chainntnfs/neutrino: don't ignore failed filter fetches
Earlier GetCFilter could return a nil-error along with a nil-filter in
cases where we failed to fetch the filter. We would just ignore the
block causing us to miss potential crucial information.

Now that GetCFilter will return an error in cases where the fetch
failed, the filter will never be nil (even for blocks with only coinbase
transactions), and we'll instead return an error.

We also increase the number of retries for the filter from the default 2
to 5.

chainntnfs/neutrino: start concurrent queues prior to connection
Similar to what was done for btcd, just to make sure we won't be blocked
on any incoming notifications, start the queues first thing during
startup.

chainntnfs/btcd: start concurrent queues prior to connection
We would establish the connection to the chain backend and start getting
block notifications before we had started the concurrent queues, which
would lead to the OnBlockConnected call being blocked, and a deadlock
(since GetBestBlock would never return).

Instead we make sure to start the queues before establishing the
connection, consuming the notifications right away.

chainntnfs/interface_test: lower mempool spend check timeout
In this commit, we lower the mempool spend check timeout to be twice as
long as the trickle interval of the miner node, which will greatly
improve the execution time of this specific test. We're able to do this
now since we can specify custom trickle intervals for our test
harnesses.

chainntnfs: acquire TxNotifier lock after closing quit chan
This prevents a deadlock while tearing down the TxNotifier if it's
currently blocked delivering a notification. By closing the quit chan
first, we ensure blocked sends/reads can exit and allow the TxNotifier
to proceed tearing down.

chainntnfs: validate conf/spend ntfn registration parameters
A height hint not being set would cause lnd to scan for the
confirmation/spend of a txid/outpoint/address from genesis.

The number of confirmations not being set within a confirmation request
would cause the internal TxNotifier to deadlock when dispatching
updates.

chainntnfs/neutrinonotify: async call GetUtxo from RegisterSpendNtfn
Since GetUtxo is a potentially long running call, we would see
RegisterSpendNtfn block in some cases, in particular on starting the
chain watcher, causing lnd to hang on startup.

This commit makes the call to GetUtxo in a go routine, letting
RegisterSpendNtfn return immediately when the notification events are
created.
