chainntnfs/interface_test: stop UnsafeStart notifiers within test
In this commit, we modify the set of tests that start the different
backend notifiers with UnsafeStart to stop them within the tests
themselves. This prevents us from running into a panic when attempting
to run the package-level tests with a filter (using test.run).

chainntnfs/interface_test: fix unreliable historical block ntfns test
After joining the two forked chains, it is necessary to ensure they both agree on the same best hash before proceeding to UnsafeStart the notifier.
This is because when the BitcoindClient starts, it retrieves its best known block then calls GetBlockHeaderVerbose on the hash of the retrieved block. This block could be a reorged block if JoinNodes has not completed sync. If it is the case that the best block retrieved has been reorged out of the chain, GetBlockHeaderVerbose errors because bitcoind sets the number of confirmations to -1 on reorged blocks, and the btcd rpc client panics when parsing a block whose number of confirmations is negative.

This parsing error is expected to be fixed, and as a more permanent solution chain backends should ensure that the `best block` they retrieve during startup has not been reorged out of the chain.

chainntnfs: extract helper test vars and functions
In this commit, we extract some of the helper test variables and
functions into their own file and guard them under a build flag. This is
needed as some unit tests will be introduced in a future commit where
most of the same functions within the interface tests are reused. In
order to prevent these variables and functions from being exportable, we
guard them by the "debug" build tag.

chaintnfs/interface_test: test notifiers handling missed blocks
Tests for the case where a chain backend skips a series of blocks, such that the notifier's best block is out of date. Also tests the case where a notifier's best block has been reorged out of the chain.

chainntnfs/interface_test: add test for client catchup on block ntfns
This tests the case where a client registers for block notifications with an outdated best block, to ensure that the client is properly caught up on the blocks that it has missed.

multi: update to latest BitcoindClient interface
In this commit, we introduce a nice optimization with regards to lnd's
interaction with a bitcoind backend. Within lnd, we currently have three
different subsystems responsible for watching the chain: chainntnfs,
lnwallet, and routing/chainview. Each of these subsystems has an active
RPC and ZMQ connection to the underlying bitcoind node. This would incur
a toll on the underlying bitcoind node and would cause us to miss ZMQ
events, which are crucial to lnd. We remedy this issue by sharing the
same connection to a bitcoind node between the different clients within
lnd.

chainntnfs/interface_test: increase wait time for mempool spends
This commit increases the time we wait for a spend client to notify a
mempool spend from 50ms to 10s. This is done to catch the case where
bitcoind would use up to 7 seconds before notifying about a mempool
spend, which wasn't caught by the test.

chainntnfs test: Test historical dispatch for mempool and non-mempool clients
This commit extends the test to exercise a scanario that wasn't properly
covered, by registering for a confirmed spend notification for a
historical spend. We also extend the test to make sure it handles buried
spends properly.

chainntfnfs test: check spend notification only on confirmation
This commit changes the chainntnfs tests to adhere to the new
RegisterSpendNtfn signature. It also makes sure that for the test
testSpendNotification, we are only getting notified when a spend is
mined, as previously btcd would notify on mempool inclusion, while
neutrino and bitcoind would notify only on confirmation, and the test
wouldn't catch this.

chainntnfs: expand historical dispatch test case to detect early dispatches
In this commit, we extend the existing historical dispatch test case to
detect any instances of early dispatches. This catches a class of bug
within a ChainNotifier when the notifier will *always* dispatch early
no matter the number of confirmations. Currently, this test fails for
the neutrino notifier.

b3509d491a chainntnfs: Add chainntfs lazy consumer test
This test adds a test for a consumer that registers for a transaction
confirmation but takes some time to check if that confirmation has
occured.

The test reveals a race condition that can cause btcdnotify to add a
confirmation entry to its internal heap twice. If the notification
consumer is not prompt in reading from the confirmation channel, this
can cause the notifier to block indefinitely.

chainntnfs: add the neutrino implementation to the set of interface tests
This commit adds a new case and proper initialization for the
NeutrinoNotifier implementation, such that it can be tested in-line
with the other implementations for proper behavior conformity.

Due to a delay when btcd sends invs for new blocks, the timeouts for
several of the tests has been extended in order to give enough time for
propagation of the new block.

This commit adds an initial rough implementation father ChainNotifier
interface for neutrino, our new light client implementation. This

implementation. As a result, a follow up commit will perform two
refactoring in order to further consolidate code.

chainntnfs: add heightHint to RegisterSpendNtfn+ RegisterConfirmationsNtfn
This commit modifies two of the main methods in the ChainNotifier
interface to be more light client friendly. In order to do so, we now
tack on an extra parameter to the methods: heightHint. This value
represents the earliest known height that the chain should be scanned
when attempting to do a dispatch from historical data.

All tests have also been updated to use these new parameters properly
when excising the expected behavior of each interface implementation.

chainntnfs/btcdnotify: properly include SpendingHeight in SpendDetails
This commit modifies the btcdnotify implementation of the ChainNotifier

was spent in the SpendDetail sent as a notification.

The set of tests have also been updated to assert that the proper
spending height is included in received notification.

chainntnfs: add the ability to cancel spend+epoch notifications
When iterating with the ChainNotifier, it currently isn’t possible to
cancel a non-dispatched yet active notificaiton intent. As a result,
this can be rather wasteful in many parts of lnd which my repeatedly
create a new spend notification depending on if/when a peer is
connected or not.

In order to fix this, we add a new `Cancel func()` field to both the
`BlockEpochEvent` and `SpendEvent` structs. This new closure attribute
allows the caller to cancel the yet-to-be-dispathed event, allowing the
ChainNotifier to free up resources.
