peer+server: make fetchLastChanUpdate _always_ fetch our own update
This commit fixes a bug that would cause us to fetch our peer's
ChannelUpdate in some cases, where we really wanted to fetch our own.

The reason this happened was that we passed the peer's pubkey to
fetchLastChanUpdate, making us match on their policy. This would lead to
ChannelUpdates being sent during routing which would have no effect on
the attempted path.

We fix this by always use our own pubkey in fetchLastChanUpdate, and
also uses the common methods within the server to be able to extract the
update even when only one policy is known.

peer: call disableChannel with disabled=false after loading channels
This to ensure now active channel is available in the router, for path
finding, as it might have been disabled if the peer has been offline a
while.

server: add goroutine watchChannelStatus
This commit adds a goroutine watchChannelStatus to the server, which
will query the switch for the status of all open channels every
InactiveChanTimeout / 4. If a channel's status has remained unchanged
during the last InactiveChanTimeout it'll send out a ChannelUpdate
setting the disabled bit accordingly.

server: let gossiper hand policy update to router
ProcessLocalAnnouncement will attempt to call UpdateEdge with the new
policy. If we call it manually before handing it to the gossiper, that
call will fail with "Outdated" and the announcement won't propagate.

server: add async peer Start() + safer cleanup
This commit adds asynchronous starting of peers,
in order to avoid potential DOS vectors. Currently,
we block with the server's mutex while peers exchange
Init messages and perform other setup. Thus, a remote
peer that does not reply with an init message will
cause server to block for 15s per attempt.

We also modify the startup behavior to spawn
peerTerminationWatchers before starting the
peer itself, ensuring that a peer is properly
cleaned up if the initialization fails. Currently,
failing to start a peer does not execute the bulk
of the teardown logic, since it is not spawned
until after a successful Start occurs.

Move noiseDial from config.go to server.go
noiseDial is only called from server.go, has nothing to do with configuration,
and moving it removes config.go's reliance on btcec and brontide.

server: prevent increasing epochErrors if conn was established
In this commit, we fix a small bug where we would increase epochErrors
by one even if connections were successfully established. Due to this,
we would stay stuck inside of the peer bootstrapper loop without
requerying for new peers.

funding+server: move initialization of funding manager into the server
In this commit, we move the initialization of the server into the
funding manager itself. We do this as it's no longer the case that _any_
RPC needs to access the funding manager. In the past, this was the
only reason that the funding manager was instantiated outside of the
server: to be able to respond to queries _before_ the server was
started.

This change also fixes a bug as atm, the funding manager will try to
register for notifications _before_ the ChainNotifier itself has fully
started.

fundingmanager: send messages to peers directly
In this commit, we modify the existing message sending functionality
within the fundingmanager. Due to each mesage send requiring to hold the
server's lock to retrieve the peer, we might run into a case where the
lock is held for a larger than usual amount of time and would therefore
block on sending the message within the fundingmanager. We remedy this
by taking a similar approach to some recent changes within the gossiper.
We now keep track of each peer within the internal fundingmanager
messages and send messages directly to them.

channeldb+server: prune link nodes on startup
In this commit, we extend the server's functionality to prune link nodes
on startup. Since we currently only decide whether to prune a link node
from the database based on a channel close, it's possible that we have
link nodes lingering from before this functionality was added on.

multi: move block epochs dependency from links to switch
In this commit, we move the block height dependency from the links in
the switch to the switch itself. This is possible due to a recent change
on the links no longer depending on the block height to update their
commitment fees.

We'll now only have the switch be alerted of new blocks coming in and
links will retrieve the height from it atomically.

server: improve initial peer bootstrapping
In this commit, we address an existing issue with regards to the inital
peer bootstrapping stage. At times, the bootstrappers can be unreliable
by providing addresses for peers that no longer exist/are currently
offline. This would lead to nodes quickly entering an exponential
backoff method used to maintain a minimum target of peers without first
achieving said target.

We address this by separating the peer bootstrapper into two stages: the
initial peer bootstrapping and maintaining a target set of nodes to
maintain an up-to-date view of the network. The initial peer
bootstrapping stage has been made aggressive in order to provide such
view of the network as quickly as possible. Once done, we continue on
with the existing exponential backoff method responsible for maintaining
a target set of nodes.

server: add support to automatically advertise external IPs using NAT
traversal

In this commit, we allow our node to automatically advertise its
connection's external IPs on the ports it is currently listening on in
order to accept inbound connections. This is only done when specifying
a NAT traversal technique when starting the daemon.

We also include a handy method that watches for dynamic IP changes in
the background. If a new IP is detected, we'll craft a new node
announcement using the new IP and broadcast it to the network.
