lnwire: add new compatibility parsing more for onion error chan updates
In this commit, we add a compatibility mode for older version of
clightning to ensure that we're able to properly parse all their channel
updates. An older version of c-lightning would send out encapsulated
onion error message with an additional type byte. This would throw off
our parsing as we didn't expect the type byte, and so we always 2 bytes
off. In order to ensure that we're able to parse these messages and make
adjustments to our path finding, we'll first check to see if the type
byte is there, if so, then we'll snip off two bytes from the front and
continue with parsing. if the bytes aren't found, then we can proceed as
normal and parse the request.

lnd_test: prevent calling Fatal in goroutine
This commit prevents an error that I've seen on travis,
wherein the test fails because a call to Fatal happens
after the test finishes. The root cause is that we call
Fatal in a goroutine that is reading from the subscribe
graph rpc call.

To fix this, we now pass an err chan back into the main
test context, where we can receive any errors and fail
the test if one comes through.

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.

autopilot: update the Node interface to return a raw bytes, not the key
In this commit, we modify the Node interface to return a set of raw
bytes, rather than the full pubkey struct. We do this as within the
package, commonly we only require the pubkey bytes for fingerprinting
purposes. Before this commit, we were forced to _always_ decompress the
pubkey which can be expensive done thousands of times a second.

pilot: remove disconnection logic from chanController
In this commit, we remove the disconnection logic within the
chanController when failing to open a channel with a peer. We do this as
it's already done within the autopilot agent, where it should be, and
because it's possible that we were already connected to this node and we
happened to disconnect them anyway.

autopilot: use updateBalance rather than tracking balance explicitly
In this commit, we modify the balanceUpdate autopilot signal to update
the balance according to what's returned to the WalletBalance callback
rather than explicitly tracking the balance. This gives the agent a
better sense of what the wallet's balance actually is.

server: avoid logging error if no links are found
In this commit, we avoid logging an error when the links associated with
a peer are not found within its termination watcher. We do this to
prevent a benign log message as the links have already been removed from
the switch.

discovery/gossiper: remove optimistic channel announcement request
In this commit, we aim to resolve an issue with nodes requesting for
channel announcements when receiving a channel update for a channel
they're not aware of. This can happen if a node is not caught up with
the chain or if they receive updates for zombie channels. This would
lead to a spam issue, as if a node is not caught up with the chain,
every new update they receive is premature, causing them to manually
request the backing channel announcement. Ideally, we should be able to
detect this as a potential DoS vector and ban the node responsible, but
for now we'll simply remove this functionality.

peer: ensure readHandler doesn't block on AddMsg to msgStream
In this commit, we add a quit channel to the AddMsg method of the
msgStream struct. Before this commit, if the queue was full, the
readHandler would block and be unable to exit. We remedy this by
leveraging the existing quit channel of the peer as an additional select
case within the AddMsg method.

lnd_test: correct force close test re: htlc limbo funds
This commit fixes a bug in the integration test, that
reliably fails after disabling the height hint cache.
The test originally asserted that the htlc funds were
in limbo, but was reading a stale copy of the force
close information. Recently, the test was amended to
provided a valid read of the force close in
96a079873a6da2f0a93adc30945971fc07c5e610. However,
the issue was not apparent until build against the
disabled height hint cache.

The test is now correct to assert that there are no
funds in limbo, as the commitment output has been
swept, but the htlcs are still in the contract
court, so the nursery is unaware of them. We also
add another sanity check to validate that there are
no pending htlcs on the force close at that point
in time.

In this commit, we select on the peer's QuitSignal to allow the caller
to unblock if the peer itself is disconnecting. With this change, we now
ensure that it isn't possible for a peer to block on this method and
prevent a graceful exit.

In this commit, we extend the Peer interface with a new QuitSignal

will allow callers to cancel any actions based on the lifetime of the

In this commit, we thread through the quit of the peer to the execution
of the apply function for a msgStream. This change ensures that if the
target is still processing the message, then the peer is able to exit
cleanly and not block insensately.

In this commit, we add a caller quit channel to waitUntilChannelOpen.
This ensures that the caller won't block forever if it needs to exit
before the funding manager exits, or the channel barrier is actually
closed.

peer: move atomic var increment in msgConsumer goroutine to defer
In this commit we move the atomic var increment that signals the
consumer goourtine has exited to the top of the method in a defer
statement. This cleans up some duplicate code and also adheres to the
pattern of using defers to signal cleaning up any dependent goroutine
state on exit.

In this commit, we raise the readHandler wait group done into a defer
statement at the top of the method. This fixes an existing but that
would cause the readHandler to declare it had exited, yet possibly still
be waiting on the chan message stream below to exit.
