routing/result_interpretation: process InvalidOnionPayload
An InvalidOnionPayload implies that the onion was successfully received
by the reporting node, but that they were unable to extract the
contents. Since we assume our own behavior is correct, this mostly
likely poins to an error in the reporter's implementation or that we
sent an unknown required type. Therefore we only penalize that single
hop, and consider the failure terminal if the receiver reported it.

htlcswitch/link: return InvalidOnionPayload failure
This commit modifies the link return an InvalidOnionPayload failure when
it cannot parse a TLV payload. The offset is left at zero, since its
unclear how useful it will be in practice and would require some
significant reworkings of the abstractions in the tlv package.

TODO: add unit tests. currently none of the test unit infrastructure is
setup to handle TLV payloads, so this would require implementing a
separate mock iterator for TLV payloads that also supports injecting
invalid payloads. Deferring this non-trival effor till a later date

htlcswitch/hop/payload: required failures with ErrInvalidPayload
This commit adds a hop.PayloadViolation enum which encompasses the cases
where the sender omits, includes, or requires a type that causes an
ErrInvalidPayload faiulre.

The existing Omitted bool is converted to this PayloadViolation, and
NewPayloadFromReader is updated to return such a failure with a
RequiredViolation when an unknown required type is detected.

The unit tests are updated to cover the three possible cases of
RequiredViolations, as well as included valid intermediate and final hop
tests.

routing/result_interpretation: fix off-by-one for incoming failure
Previously we would not mark a success for the first hop if the fail
source index was 2. We also add a test to assert this behavior.

31bf542276 lnrpc: Add experimential uptime and lifetime fields to list channels
This commit adds the total observed lifetime of a channel and the
totaluptime of its remote peer to the lnrpc channel struct. These
fields are marked as experimential because they are subject to
change.

routing: use unified policy for path finding
In this commit we change path finding to no longer consider all channels
between a pair of nodes individually. We assume that nodes forward
non-strict and when we attempt a connection between two nodes, we don't
want to try multiple channels because their policies may not be identical.
Having distinct policies for channel to the same peer is against the
recommendation in the spec, but it happens in the wild. Especially since
we recently changed the default cltv delta value.

What this commit introduces is a unified policy. This can be looked upon
as the greatest common denominator of all policies and should maximize
the probability of getting the payment forwarded.

1e86589bee chanfitness: Add channel event store
This commit adds a channel event store to the channel fitness
package which is used to manage tracking of a node's channels.
It adds tracking for channel open/closed and peer online/offline
events for all channels that a node has open.

Events are consumed from channelNotifier and peerNotifier event
subscriptions. If either of these subscriptions is cancelled,
channel scoring stops, because both subscriptions are expected
to run until node shutdown.

Two functions are exposed to allow external callers to get uptime
information about a channel. GetLifespan returns the period over
which the channel has been monitored. GetUptime returns the channel's
uptime over a specified period. Callers can use these functions to
get the channel's remote peer uptime over its entire lifetime, or
a subset of that period.

744876003d chanfitness: Add channel event log structure
This commit adds a chanfitness package which will be used to track
channel health and performance metrics. It adds a channel event
structure which will be used to track channel opens/closes and peer
uptime.

The eventLog implements an uptime function which calcualtes uptime
over a given period and a lifespan function which returns the time
when the log began monitoring the channel and, if the channel is
closed, the time when it stopped moitoring it.

818c302d46 routing: use nodeWithDist instead of vertex to avoid map access
The same nodeWithDist was fetched from the map for every channel it has.
This struct is not mutated so it can be fetched before and reused.

df70095ad0 routing: optimize path finding structures
distance map now holds the edge the current path is coming from,
removing the need for next map.

Both distance map and distanceHeap now hold pointers instead of the full
struct to reduce allocations and copies.

Both these changes reduced path finding time by ~5% and memory usage by
~2mb.

fc36df0e60 routing: avoid unneeded map access
`processEdge` basically had 4 expensive operations: 3 map accesses and
updating the heap. This removes one of those for a small performance
gain.

3e60a23632 routing: pre-allocate the distance map to an estimated node count
Pre-sizing these structures avoids a lot of map resizing, which causes
copies and rehashing of entries. We mostly know that the map won't
exceed that size, and it doesn't affect memory usage in any significant
way.

2141713936 routing: avoid walking all nodes for path finding if we don't need to
Calling `ForEachNode` hits the DB, and allocates and parses every node
in the graph. Walking the channels also loads nodes from the DB, so this
meant that each node was read/parsed/allocated several times per run.

This reduces runtime by ~10ms and memory usage by ~4mb.

fundingmanager: make SendToPeer sync
Since the funding flow requires messages to go through, make use of
sync version of SendToPeer. Using the async version we would risk that
the message was dropped and the process would stall (it would properly
continue after a restart though).

htlcswitch: fix returned failure for insufficient balance
In the scenario where the requested channel does not have enough balance
and another channel towards the same node generates a different failure,
we erroneously returned UnknownNextPeer instead of the expected
TemporaryChannelFailure.

This commit rewrites the non-strict forwarding logic in the switch to
return the proper failure message. Part of this is moving the link
balance check inside the link.
