routing: change representation of pair results in mc
This commit changes the in-memory structure of the mission control
state. It prepares for calculation of a node probability. For this we
need to be able to efficiently look up the last results for all channels
of a node.

routing+routerrpc: take max cltv limit into account within path finding
With the introduction of the max CLTV limit parameter, nodes are able to
reject HTLCs that exceed it. This should also be applied to path
finding, otherwise HTLCs crafted by the same node that exceed it never
left the switch. This wasn't a big deal since the previous max CLTV
limit was ~5000 blocks. Once it was lowered to 1008, the issue became
more apparent. Therefore, all of our path finding attempts now have a
restriction of said limit in in order to properly carry out HTLCs to the
network.

routing: update 3d party channel verification to use new chanvalidate package
In the process of moving to use the new package, we no longer need to
fetch the outpoint directly, and instead only need to pass the funding
transaction into the new verification logic.

multi: update internals to support updating max htlc
In this commit, we update the router and link to support users
updating the max HTLC policy for their channels. By updating these internal
systems before updating the RPC server and lncli, we protect users from
being shown an option that doesn't actually work.

routing+discovery: extract local channel manager
The policy update logic that resided part in the gossiper and
part in the rpc server is extracted into its own object.

This prepares for additional validation logic to be added for policy
updates that would otherwise make the gossiper heavier.

It is also a small first step towards separation of our own channel data
from the rest of the graph.

routing/route/route: prevent modification of hop.TLVRecords
Currently the underlying array backing the hop's TLVRecords is modified
when combining custom records with the primitive forwarding info. This
commit uses a fresh slice to prevent modifications from mutating the

routing: process successes in mission control
This commit modifies paymentLifecycle so that it not only feeds
failures into mission control, but successes as well.
This allows for more accurate probability estimates. Previously,
the success probability for a successful pair and a pair with
no history was equal. There was no force that pushed towards
previously successful routes.

routing: extend path finding to be TLV-EOB aware, allow dest TLV records
In this commit, we extend the path finding to be able to recognize when
a node needs the new TLV format, or the legacy format based on the
feature bits they expose. We also extend the `LightningPayment` struct
to allow the caller to specify an arbitrary set of TLV records which can
be used for a number of use-cases including various variants of
spontaneous payments.

routing/route+tlv: add new TLV-EOB awareness to Hop+Route
In this commit, we extend the Hop struct to carry an arbitrary set of
TLV values, and add a new field that allows us to distinguish between
the modern and legacy TLV payload.

We add a new `PackPayload` method that will be used to encode the
combined required routing TLV fields along any set of TLV fields that
were specified as part of path finding.

Finally, the `ToSphinxPath` has been extended to be able to recognize if
a hop needs the modern, or legacy payload.

routing: stricter payment result interpretation
This commit overhauls the interpretation of failed payments. It changes
the interpretation rules so that we always apply the strongest possible
set of penalties, without making assumptions that would hurt good nodes.

Main changes are:

- Apply different rule sets for intermediate and final nodes. Both types
of nodes have different sets of failures that we expect. Penalize nodes
that send unexpected failure messages.

- Distinguish between direct payments and multi-hop payments. For direct
payments, we can infer more about the performance of our peer because we
trust ourselves.

- In many cases it is impossible for the sender to determine which of
the two nodes in a pair is responsible for the failure. In this
situation, we now penalize bidirectionally. This does not hurt the good
node of the pair, because only its connection to a bad node is
penalized.

- Previously we always penalized the outgoing connection of the
reporting node. This is incorrect for policy related failures. For
policy related failures, it could also be that the reporting node
received a wrongly crafted htlc from its predecessor. By penalizing the
incoming channel, we surely hit the responsible node.

- FailExpiryTooSoon is a failure that could have been caused by any node
up to the reporting node by delaying forwarding of the htlc. We don't
know which node is responsible, therefore we now penalize all node pairs
in the route.

routing: penalize all node pairs for unknown outcomes
When an undecryptable failure comes back for a payment attempt, we
previously only penalized our own outgoing connection. However,
any node could have caused this failure. It is therefore better to
penalize all node connections along the route. Then at least we know for
sure that we will hit the responsible node.

routing/test: do not test local channel mission control
This commit updates existing tests to not rely on mission control for
pruning of local channels. Information about local channels should
already be up to date before path finding starts. If not, the problem
should be fixed where bandwidth hints are set up.

routing: isolate failure interpretation from mission control
This commit moves the payment outcome interpretation logic into a
separate file. Also, mission control isn't updated directly anymore, but
results are stored in an interpretedResult struct. This allows the
mission control state to be locked for a minimum amount of time and
makes it easier to unit test the result interpretation.

routing: convert to node pair based
Previously mission control tracked failures on a per node, per channel basis.
This commit changes this to tracking on the level of directed node pairs. The goal
of moving to this coarser-grained level is to reduce the number of required
payment attempts without compromising payment reliability.

Align naming better with the lightning spec. Not the full name of the
