LGTM 🍹

In this commit, we modify the look up for inbound peers to ensure that
we connect to the "freshest" address until we need to execute the
peerTerminationWatcher. We do this as it's possible for a channel to be
created by the remote peer during our session. If we don't query for the
node's address at the latest point, then we'll miss this new node
announcement for the node.
…a scheduled callback

In this commit, we ensure that if we're already ignoring a connection,
then we also ignore the pending persistent connection request.
Otherwise, we'll move to accept the replaced connection, but then
continue to attempt connection requests.
…nection logic

With the recent bug fixes in the peer connection, it's no longer the
case that just disconnecting a certain peer causes it to no longer
connect to the other. As a result, we now shutdown Alice to ensure no
reconnection occurs. We'll then later restart alice when we restart
dave.
In this commit, we finish the fix for the inbound/outbound peer bool in
the server. The prior commit forgot to also flip the inbound/output maps
in Inbound/Outbound peer connected. As a result, the checks were
incorrect and could cause lnd to refuse to accept any more inbound
connections in the case of a concurrent connection attempt.

As the PR is incomplete, once #1351 is finalized, we should make a joint PR to confirm it resolves the current issues.

In this commit, we fix the logging when adding new gossip syncers. The
old log would log the byte array, rather than the byte slice. We fix
this by slicing before logging.
…Link

In this commit, we modify the interfaceIndex to no longer key the second
level of the index by the ChannelLink. Instead, we'll use the chan ID as
it's a stable identifier, unlike a reference to an interface.
In this commit, we fix a bug in the way we handle removing items from
the interfaceIndex. Before this commit, we would delete all items items
with the target public key that of the peer that owns the link being
removed. However, this is incorrect as the peer may have other links
sill active.

In this commit, we fix this by first only deleting the link from the
peer's index, and then checking to see if the index is empty after this
deletion. Only if so do we delete the index for the peer all together.
In this commit we fix an existing bug which could cause internal state
inconsistency between then switch, funding manager, and the peer. Before
this commit, we would _always_ add a new channel to the channelManager.
However, due to recent logic, it may be the case that this isn't the
channel that will ultimately reside in the link. As a result, we would
be unable to process incoming FundingLocked messages properly, as we
would mutate the incorrect channel in memory.

We remedy this by moving the inserting of the new channel into the
activeChannels map until the end of the loadActiveChannels method, where
we know that this will be the link that persists.
