htlcswitch/link: batch write to preimage cache
This commit makes use of the batched AddWitness
method of the WitnessCache, in order to avoid
performing one write for each accepted preimage.

Additionally, this fixes an existing hole in the
consistency guarantees since the batched writes
are now guaranteed to take place before accepting
the next CommitSig. Previously, these writes were
processed in an unsynchronized go routine that
could be delayed arbitrarily long before being
executed.

With this change, the async_payments_benchmarks
actually shows a slight improvement in
performance, presumably because we no longer do
an individual write per preimage, even though
the execution is now explicitly in the critical
path. There is likely also a marginal performance
improvement from the reduction in goroutine
overhead.

multi: make AddPreimage variadic, optimistically compute key
In this commit, we modify the WitnessCache's
AddPreimage method to accept a variadic number
of preimages. This enables callers to batch
preimage writes in performance critical areas
of the codebase, e.g. the htlcswitch.

Additionally, we lift the computation of the
witnesses' keys outside of the db transaction.
This saves us from having to do hashing inside
and blocking other callers, and limits extraneous
blocking at the call site.

build: update to latest neutrino build
In this commit, we update lnd to build against the latest version of
neutrino. This new version fixes a bug left behind as a result of the
btcd filter bug fix. When we were comparing filters in order to ban
invalid peers, we used the old OP_RETURN filtering rather than the new
one. As a result, we might've rejected a valid filter/block as we were
applying the old (incorrect) rules.

server+discovery: send channel updates to remote peers reliably
In this commit, we also allow channel updates for our channels to be
sent reliably to our channel counterparty. This is especially crucial
for private channels, since they're not announced, in order to ensure
each party can receive funds from the other side.

discovery/reliable_sender: implement message-agnostic reliable sender
In this commit, we implement a new subsystem for the gossiper that
uses some of the existing logic for resending channel announcement
signatures and implements it in a way to make it message-agnostic,
meaning that any type of message can be resent. Along the way we also
modify the way this works to prevent multiple goroutines per peer _and_
message.

A peerHandler will be spawned for each peer for which we attempt to send
a message reliably to. This handler is responsible for managing requests
to reliably send messages to a peer while also taking the peer's
connection lifecycle into account by requesting notifications for when
the peer connects/disconnects. A peer connection notification is first
requested to determine when we should attempt to send any pending
messages. After the messages are sent, a peer disconnection notification
is requested to ensure we don't continue to request connection
notifications while the peer remains connected. Once there are no more
pending messages left to be sent for a given peer, the peerHandler can
be torn down.

channeldb: add gossiper message store key migration
In this commit, we introduce a migration for the message store
sub-bucket that will migrate all keys within it to a new key format.
This new key format is composed of the peer's public key, followed by
the short channel ID, followed by the message type. This migration is
needed in order to provide backwards-compatibility with messages that
were previously stored before the introduction of the new key format.

discovery/message_store: add gossip message store
In this commit, we add a new store within the database that'll be
responsible for storing gossip messages which we need to reliably send
to peers. This aims to replace the current messageStore that exists
within the gossiper, so much of this logic is borrowed from there.
One of the main differences between the two is that we now index
messages with a new key format in which we take into account the
message's type. This allows us to store different messages for a
specific channel with a peer. The old key format is still supported in
order to prevent a database migration.

This commit adds a method SetNodesScores to the WeightedCombAttachment
heuristic.

Since the heuristic keeps a list of sub-heuristics, it will attempt to
recursively apply the scores to the sub heuristics.
