htlcswitch: remove batch counter
Now that channel exposes the number of pending local updates, it is no
longer necessary to track the batch size separately in the link.

htlcswitch+lnwallet: replace updateNeeded by check on channel itself
Instead of tracking local updates in a separate link variable, query
this state from the channel itself.

This commit also fixes the issue where the commit tx was not updated
anymore after a failed first attempt because the revocation window was
closed. Also those pending updates will be taken into account when the
remote party revokes.

htlcswitch: check for signature owed in link
Previously the channel method FullySynced was used to decide whether to
send a new commit sig message. However, it could happen that FullySynced
was false, but that we didn't owe a commitment signature. Instead we
were waiting on the other party to send us a signature. If that
happened, we'd send out an empty commit sig. This commit modifies the
condition that triggers a new commit sig and fixes this deviation from
the spec.

lnwallet: log empty commit sig event
To facilitate the logging, this commit adds a new OweCommitment method.
For the logging, we only need to consider the remote perspective. In a
later commit, we'll also start using the local perspective to support
the decision to send another signature.

lntest/itest: expand testSingleHopSendToRoute matrix
In this commit, we refactor the testSingleHopSendToRoute test to support
table driven tests for various endpoints and payment types. Currently
only the main rpcserver's SendToRoute is tested, so we also add
support the SendToRouteSync and the routerrpc's SendToRoute.

The tests are also modified to have each endpoint perform a single-hop,
single-shot MPP payment. This asserts that the Hop messages are being
properly unmarshalled and that setting correctly yields a successful
payment. At the momemnt the receiver does not actually verify or use the
MPP fields presented in the onion, though this test will be expanded
later as those pieces are assembled.

lnrpc/routerrpc/router_backend: populate and unmarshal mpp fields
This commit parses mpp_total_amt_msat and mpp_payment_addr from the
SendToRoute rpc and populates an MPP record on the internal hop
reprsentation. When the router goes to encode the onion packet, these
fields will be serialized for the destination. We also populate the mpp
fields when marshalling routes in rpc responses.

lnrpc/rpc.proto: add mpp fields to Hop message
This commit add mpp_total_amt_msat and mpp_payment_addr to the Hop
message. Doing so enables users submitting mpp payments via rpc to
set these parameters for the destination. In addition, it will allow us
to display these fields in rpc responses.

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).

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.
