elnosh 6f49bea52b server: remove accountability signal experiment period
In the previous iteration with endorsement
signaling, the recommendation was for the sender to
set it to 1 and that could have had privacy concerns
when first deploying given that the default was to
downgrade the signal to 0. In the latest proposal
the recommended default for both sending and
forwarding nodes is to set `accountable` to 0.
As a result, the dates have been removed given
that there are no privacy risks associated
with relaying the signal with zero values.

George Tsagkarelis 6dff1bd5de htlcswitch+peer: set and read aux custom records
This is the final step, we actually call the interface and either
provide or retrieve the custom features over the message. We also notify
the aux components when channel reestablish is received.

Boris Nagaev f3d52ba7a8 htlcswitch: don't pass err.Error() to failf
It resulted in interpreting the error message as a format string.
Use failf("%v", err) instead.

yyforyongyu 127b0e9f41 multi: add new config QuiescenceTimeout
This commit makes removes the `defaultQuiescenceTimeout` and makes it
configurable as different nodes have different network environment. In
addition the default timeout has been increased from 30s to 60s.

yyforyongyu ca770bb4af htlcswitch: notify channel active after reforwarding
The channel should only be considered active when its pending tasks are
finished, which includes,
1. sync channel state via reestablish.
2. send previous shutdown msg.
3. reset the mailbox's packets.
4. reforwarding logs loaded from restart.

When the above tasks are finished, the channel can be considered as
fully resumed from its previous disconnection.

yyforyongyu 755bb09a73 htlcswitch: skip decoding hop if the htlc is already acked
We now move the check earlier in the loop so we don't even need to
decode the hop for already processed ADDs.

yyforyongyu fb95458a1b htlcswitch: skip checking replays for reforwarded packets
We now rely on the forwarding package's state to decide whether a given
packet is a reforwarding or not. If we know it's a reforwarding packet,
there's no need to check for replays in the `sharedHashes` bucket, which
behaves the same as if we are querying the `batchReplayBkt`.

ziggie 6feed32288 htlcswitch: exit early if no adds are in the fwd pkg
This lead to the case that we would always record a HTLC
two times in the decayed log protection which is not necessary
in the first place.

Oliver Gugger 56d2381f51 htlcswitch+routing: add funding blob to PaymentBandwidth
For certain auxiliary bandwidth checks we need to know the funding blob
that was present when the channel was created.

Oliver Gugger 5fb0f43172 htlcswitch+routing: add htlc blob to ShouldHandleTraffic
Whether we should let the aux bandwidth manager decide what the
bandwidth of a channel is should also depend on whether the HTLC is a
custom HTLC, not just the channel.

George Tsagkarelis d0ef248ae2 htlcswitch: add HtlcView as PaymentBandwidth argument
In order to get more precise bandwidth reports, we also need to provide
this method with the latest htlc view. Since aux data is committed to in
the channel commitment, some uncommited HTLCs may not be accounted for,
so we need to manually provide them via the HTLC view.

yyforyongyu 5a72d5258f htlcswitch+itest: catch link quit signal when processing hodlQueue
This commit makes sure when processing resolutions, e.g, settling
invoices, when the link is already broken, the process would exit with
an error. This fixes the issue we found in the itest, where an
unexpected empty remote pending commitment was created although the
remote peer is already offline.

channel or not, we return an explicit boolean.

ziggie 17e37bd7c2 multi: introduce new traffic shaper method.
We introduce a new specific fail resolution error when the
external HTLC interceptor denies the incoming HTLC. Moreover
we introduce a new traffic shaper method which moves the
implementation of asset HTLC to the external layers.
Moreover itests are adopted to reflect this new change.

Elle Mouton 950194a2da htlcswitch+go.mod: use updated fn.ContextGuard
This commit updates the fn dep to the version containing the updates to
the ContextGuard implementation. Only the htlcswitch/link uses the guard
at the moment so this is updated to make use of the new implementation.

Oliver Gugger a2e78c3984 htlcswitch: thread through packet's inbound wire records
For calculating the available auxiliary bandwidth of a channel, we need
access to the inbound custom wire records of the HTLC packet, which
might contain auxiliary information about the worth of the HTLC packet
apart from the BTC value being transported.

Oliver Gugger 117c6bc781 multi: move routing.TlvTrafficShaper => htlcswitch.AuxTrafficShaper
With this commit we move the traffic shaper definition from the routing
package to the HTLC switch package as a preparation for being able to
use it there as well.
At the same time we rename it to AuxTrafficShaper to be more in line
with the other auxiliary components.
