tlv/truncated: add non-generic encoders for truncated types
These encoders can be composed to create composite types without
incurring additional allocations that would be required to pass the
truncated types through the generic interface.

chainfee: create new chainfee package extracting fees from lnwallet
In this commit, we create a new chainfee package, that houses all fee
related functionality used within the codebase. The creation of this new
package furthers our long-term goal of extracting functionality from the
bloated `lnwallet` package into new distinct packages. Additionally,
this new packages resolves a class of import cycle that could arise if a
new package that was imported by something in `lnwallet` wanted to use
the existing fee related functions in the prior `lnwallet` package.

multi: convert the existing channeldb.ChannelType uint8 into a bit field
In this commit, we convert the existing `channeldb.ChannelType` type
into a _bit field_. This doesn't require us to change the current
serialization or interpretation or the type as it is, since all the
current defined values us a distinct bit. This PR lays the ground work
for any future changes that may introduce new channel types (like anchor
outputs), and also any changes that may modify the existing invariants
around channels (if we're the initiator, we always have the funding
transaction).

autopilot: trigger agent channel open on new scores
This commit adds a new signal to the autopilot agent, meant to signal
when any of the available heuristics has gotten an update.

external scores have been updated.

htlcswitch/hop/payload: apply known constraints if required failure
This commit modifies the NewPayloadFromReader to apply known
presence/omission contraints in the event that the tlv parser returns an
unknown required type failure.

Now that the parser has been modified to finished parsing the stream to
obtain a proper parsed type set, we can accurately apply these higher
level validation checks. This overrides required type failures, such
that they are only returned if the sender properly abided by the
constraints on fields for which we know.

The unit tests are updated to create otherwise valid payloads that then
return unknown required type failures. In one case, a test which
previously returned an unknown required type failure is made to return
an included failure for the sid, indicating the unknown required type 0
is being overruled.

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.

routerrpc: add mc probability query rpc
Probabilities are no longer returned for querymc calls. To still provide

routing: remove embedded struct from timedPairResult
This prepares for decoupling the result interpretation of a single

the last success and last failure requires this decoupling.

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.
