[htlcswitch] Optionally force close channel on link failure

Revert "test: account for block race by mining additional block in remote htlc force close test"
Before the previous commit, we assumed the HTLC's timeout transaction
would be the only transaction in the mempool. In reality, after mining
some blocks for the HTLC to expire and waiting for the timeout
transaction to arrive in the mempool, at times we would instead detect
the funding output's sweeping transaction and proceed the test with this
assumption, leading to the case where we would have to mine extra blocks
to include the HTLC sweeping transaction. This has been resolved in the
previous commit, so this fix is no longer needed.

This reverts commit e54f1ea4dbe59b2e53a94774995ae1711746c2f8.

test: detect funding output sweep tx after force close
In this commit, we address an existing flake that would be triggered
when testing HTLC timeouts. After force closing a channel and generating
enough blocks to expire an HTLC, we would wait for a transaction to
arrive in the mempool and assumed it was the timeout transaction.
Instead, we'd detect the funding output sweep transaction and attempt to
proceed with the test with the incorrect assumption of the timeout
transaction being broadcast.

lnd_test: add testFailingLink
This commit adds an integration test that checks that in case a channel
counterparty tries to settle an HTLC with the wrong preimage, the
channel is failed and force closed.

properly remove the link and force close the channel.

htlcswitch/link: make fail() call OnChannelFailure with LinkFailureError
Adds a new closure OnChannelFailure to the link config, which is called
when the link fails. This function closure should use the given
LinkFailureError to properly force close the channel, send an error to
the peer, and disconnect the peer.

htlcswitch/linkfailure: define LinkFailureError
This commit introduces a new error type LinkFailureError which is used
to distinguish the different kinds of errors that we can encounter
during link operation. It encapsulates the information necessary to
decide how we should handle the error.

test: use graph notifications to receive node announcement

announcement.

lntest: wait until channel is active within AssertChannelExists
In this commit, we fix a race condition where at times we open a channel
between two parties and immediately try to send payments over it. At
times this would fail due to the channel link not being fully registered
in the HTLC switch.

channeldb/channel: update IsPending godoc
The pending state definitin in ChannelCloseSummary was slightly changed
in such a way that channels that has had their commitment broadcasted
now is no longer considered "pending close". They now instead stay in
the open chan bucket with the ChanStatus "CommitmentBroadcasted" until
their commitment is confirmed. This commit updates the IsPending godoc
to reflect this.

htlcswitch: ensure we don't attempt to create fwding events for fails
In this commit, we fix an existing source of a panic, that could at
times lead to a deadlock. If the circuit returned from closeCircuit
didn't have an outgoing key (as it was an incomplete forward), then we
would attempt to de-ref a nil pointer. This would trigger a panic, and
the runtime would start to unwind the stack, and execute each defer in
line. A deadlock can arise here, as in the defer at the root goroutine,
we need to grab the fwdingEventMtx. However, we already have it at the
panic site.

We fix this issue by ensuring we only attempt to add the event if it's a
_settle_ and also actually has an outgoing circuit (which it should
already, just a defensive check).

channeldb: modify updateChanBucket to no longer auto-create buckets
In this commit, we modify the existing updateChanBucket function to no
longer auto-create buckets if they don't exist. We do this in order to
fix a class of bug that could arise wherein after a channel has actually
be closed (and the parent buckets removed) a method that mutates the
channel state is called, which then re-creates the relevant set of
buckets. As a result, subsequent calls to any RPCs which need to read
all the channels will fail as most of the fields won't actually be
populated.

After this commit, the fullSync method is the only one that's able to
create the full bucket hierarchy.

contractcourt/chain_arbitrator: markChanClosed->notifyChanClosed
We no longer have to mark the channel as fully closed in the database,
as it is done directly in the chainWatcher. Instead, we stop the watcher
and delete it from the set of active watchers.

contractcourt/chain_watcher: mark fully closed in dispatchCoopClose
This commit makes the dispatchCooperativeClose method mark the channel
fully closed directly, without registering for confirmation
notifications first. We can do this as recent changes to the
contractcourt changed the definition of a closed channel in the database
to have had its closing tx confirmed, and we only dispatch the
cooperative close once the transaction has 1 confirmation.

We also rename the markChanClosed method to notifyChanClosed, to more
clearly indicate that the ChainArbitrator no longer has to mark the
channel fully closed in the database.

chancloser: don't log potential closes to the chainwatcher
This commit stops the chan closer from sending the potential coop close
transactions to the chainwatcher, as this is no longer needed. The
chainwatcher recently was modified to watch for any potential close, and
will because of this handle the close regardless of which one appears in
chain.

When the chancloser broadcast the final close transaction, we mark it as
CommitmentBroadcasted in the database.

lnwallet: add assertion in createCommitmentTx to detect overdraw attempts
In this commit, we add a precautionary assertion at the end of
createCommitmentTx. This assertion is meant to ensure that we don't
accept or propose a commitment transaction that attempts to send out
more than it was funded with.

lnwallet: add additional assertions to TestChanReserve, fix bug before final case
In this commit, we add a series of additional balance assertions to
ensure that the balance of the two channels at each stage match up with
our expectations. Additionally, we also fix a bug at the end of the test
which would result in Alice accidentally overdrawing her balance in the
channel. The issue was that the test attempted to settle HTLCs that
weren't yet fully locked in. We fix this by adding an additional state
transition before settling the final set of HTLCs.
