lnwallet/channel: add more info in case of crash
This commit adds a call to panic in case the HTLC we are looking for is
not found in the update log. It _should_ always be there, but we have
seen crashes resulting from it not being found. Since it will crash with
a nil pointer dereference below, we instead call panic giving us a bit
more information to work with.

lnwallet/channel: return missing errors
This commit corrects a few cases where we would encounter errors, but
return nil by mistake.

lnwallet: modify NewUnilateralCloseSummary to be aware of pending remote commits
In this commit, we modify the NewUnilateralCloseSummary to be able to
distinguish between a unilateral closure using the lowest+highest
commitment the remote party possesses. Before this commit, if the remote
party broadcast their highest commitment, when they have a lower
unrevoked commitment, then this function would fail to find the proper
output, leaving funds on the chain.

To fix this, it's now the duty of the caller to pass remotePendingCommit
with the proper value. The caller should use the lowest unrevoked
commitment, and the height hint of the broadcast commitment to discern
if this is a pending commitment or not.

lnwallet: move CreateTestChannels to new test_utils.go
In this commit, we move a set of useful functions for testing channels
into a new file. The old createTestChannels has been improved as it will
now properly set the height hint on the first created commitments, and
also no longer accepts any arguments as the revocation window no longer
exists.

channeldb: additionally store static channel information in CloseChannelSummary
In this commit, we extend the CloseChannelSummary by also storing: the
current unrevoked revocation for the remote party, the next pending
unused revocation, and also the local channel config. We move to store
these as the provide an extra level of defense against bugs as we'll
always store information required to derive keys for any current and
prior states.

test: fix revocation integration test flake
In this commit, we fix an existing flake within the set of revocation
integration tests. Right after Bob's restart, we attempt to force close
the channel. However, it may be the case that the chain arbitrator
hasn't yet been created. As a result, the request to force close the
channel will fail. We easily fix this by wrapping the force close
attempt in a WaitPredicate.

test: account for block race by mining additional block in remote htlc force close test
This commit is similar to a recent commit which attempts to account for
internal block races by mining a second block if the initial assertion
for HTLC state fails. This can happen again if by the time that the
sweeping transaction is broadcast, it doesn't make it into the next
block mine.

test: attempt to account for internal block race in htlc force close test
In this commit, we modify the
testMultHopRemoteForceCloseOnChainHtlcTimeout test slightly to attempt
to account for a block race between the arrival of a message betwen the
contract resolver and the utxo nursery. If this message arrives "late"
(relative to the speed with which we mine blocks in test), then it'll be
detected as such by the utxo nursery. However, since we attempt to mine
a precise number of blocks, if this happens, then we'll never actually
mine that extra block to trigger a broadcast of the sweep transaction.

htlcswitch: move link trimming to link start up
In this commit, we fix a race in the set of TestChannelLinkTrimCircuits*
tests. Before this commit, we would trim the circuits in the htlcManager
goroutine. However, this was problematic as the scheduling order of
goroutines isn't predictable. Instead, we'll now trim the circuits in
the Start method.

Additionally, we fix a series of off-by-2 bugs in the tests themselves.

peer: ensure msgConsumer sets the shutdown variable on exit
In this commit, we fix a bug that could at times cause a deadlock when a
peer is attempting to disconnect. The issue was that when a peer goes to
disconnect, it needs to stop any active msgStream instances. The Stop()
method of the msgStream would block until an atomic variable was set to
indicate that the stream had fully exited. However, in the case that we
disconnected lower in the msgConsumer loop, we would never set the
streamShutdown variable, meaning that msgStream.Stop() would never
unblock.

The fix for this is simple: set the streamShutdown variable within the
quit case of the second select statement in the msgConsumer goroutine.

htlcswitch/link: adds HodlFlag breakpoints
This commit inserts an initial set of HodlFlags into
their correct places within the switch. In lieu of the
existing HtlcHodl mode, it is been replaced with a
configurable HodlMask, which is a bitvector representing
the desired breakpoints. This will allow for fine grained
testing of the switch's internals, since we can create
arbitrary delays inside a otherwise asynchronous system.
