8fcd6b56cb chainntnfs: expand test for mempool spend notifications

Fixes #1074.

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: add testSpendNotificationMempoolSpends for btcd backend
The test is only run for the btcd backend for now, as notifying on
mempool spends doesn't work for neutrino and bitcoind.

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.

chainntnfs/neutrinonotify: add ChainNotifier implementation for neutrino
This commit adds an initial rough implementation father ChainNotifier
interface for neutrino, our new light client implementation. This
implementation largely borrows from the existing BtcdNotifier
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
interface to properly include the height in which the watched output
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.

multi: update btcsuite API's to latest upstream changes
This commit makes a large number of minor changes concerning API usage
within the deamon to match the latest version on the upstream btcsuite
libraries.

The major changes are the switch from wire.ShaHash to chainhash.Hash,
and that wire.NewMsgTx() now takes a paramter indicating the version of
the transaction to be created.

chainntnfs: ConfirmationEvent now returns details of tx confirmation
This commit modifies the ChainNotifier interface, specifically the
ConfirmationEvent struct to now return additional details concerning
the exact location in the chain that the transaction was confirmed at.

This information will be very useful within the new routing package, as
within the network, channels are identified via their channel-ID which
is a compact encoding of: blockHeight | txIndex | outputIndex

chainntnfs: properly account for partial historical confirmation dispatch
This commit modifies the recently added logic to the ChainNotifier to:
  1. Fix the off-by-one confirmation error that was missed due a flaky
test
  2. Ensure that partial historical confirmations are properly handled.

The partial hostile confirmation case arises when a transaction already
a non-zero number of confirmations when the notification is registered,
but less than what would trigger the confirmation notification. To fix
this, transaction which have a partial number of confirmation are now
properly inserted into the confHeap, skipping first first phase for
notifications.

909c3f8df9 chainntfs: add checks for previously confirmed transactions and spends
Without these checks, “zombie” notification requests that would never
be dispatched could be registered. This would occur if notification
requests were made for events (transaction confirmation and output
spent) that had already been recorded on the blockchain.

chainntnfs: add multi-client txid support for confirmation notifications
This commit adds multi-client support for confirmation notification of
the same transaction. Within the daemon there might be scenarios where
multiple goroutines are waiting for the same transaction to be
confirmed in order to properly fulfill their tasks. Previously if
multiple clients were registered for the same txid confirmation
notification, then only the client who registered last would receive
the notification.

chainntnfs: add cross interface implementation tests
This commit refactors the existing chainntnfns package in order to
allow more easily allow integration into the main system, by allowing
one to gain access to a set of end-to-end tests for a particular
ChainNotifier implementation.

In order to achieve this, the existing set of tests for the only
concrete implementation (`BtcdNoitifer`) have been refactored to test
against all “registered” notifier interfaces registered. This is
achieved by creating the concept of a “driver” for each concrete
`ChainNotifer` implementation. Once a the package of a particular
driver is imported, solely for the side effects, the init() method
automatically registers the driver.

Additionally, the documentation in various areas of the package have
been cleaned up a bit.
