f0e668974e htlcswitch/link: verify an htlc is not too large in HtlcSatifiesPolicy
Before forwarding an HTLC, ensure that the amount to forward
including fees does not exceed the max HTLC set for the channel
link.

20b3114100 htlcswitch+lnwallet+peer: default max htlc in fwding policy of new chans
In this commit, we set a default max HTLC in the forwarding
policies of newly open channels.

The ForwardingPolicy's MaxHTLC field (added in this commit)
will later be used to decide whether an HTLC satisfies our policy before
forwarding it.

To ensure the ForwardingPolicy's MaxHTLC default matches the max HTLC
advertised in the ChannelUpdate sent out for this channel,  we also add
a MaxPendingAmount() function to the lnwallet.Channel.

htlcswitch/link: batch write to preimage cache
This commit makes use of the batched AddWitness
method of the WitnessCache, in order to avoid
performing one write for each accepted preimage.

Additionally, this fixes an existing hole in the
consistency guarantees since the batched writes
are now guaranteed to take place before accepting
the next CommitSig. Previously, these writes were
processed in an unsynchronized go routine that
could be delayed arbitrarily long before being
executed.

With this change, the async_payments_benchmarks
actually shows a slight improvement in
performance, presumably because we no longer do
an individual write per preimage, even though
the execution is now explicitly in the critical
path. There is likely also a marginal performance
improvement from the reduction in goroutine
overhead.

multi: make AddPreimage variadic, optimistically compute key
In this commit, we modify the WitnessCache's
AddPreimage method to accept a variadic number
of preimages. This enables callers to batch
preimage writes in performance critical areas
of the codebase, e.g. the htlcswitch.

Additionally, we lift the computation of the
witnesses' keys outside of the db transaction.
This saves us from having to do hashing inside
and blocking other callers, and limits extraneous
blocking at the call site.

08750f180b multi: deprecate IncorrectHtlcAmount onion error
In this commit, we deprecate the `IncorrectHtlcAmount` onion error.
We'll still decode this error to use when retrying paths, but we'll no
longer send this ourselves. The `UnknownPaymentHash` error has been
amended to also include the value of the payment as well. This allows us
to worry about one less error.

htlcswitch/switch: check EligibleToForward in HasActiveLink
This commit modifies the behavior of the
HasActiveLink method within the switch to
only return true if the link is in the
link index and is eligible to forward
HTLCs.

The prior version returns true whenever
the link is found in the link index,
which may return true for pending
channels that are not actually active.

e71151f56a htlcswitch/link: return FinalFailExpiryTooSoon for last htlc
In this commit, we fix a minor discrepancy with the spec. We should
return a FinalFailExpiryTooSoon error, rather than a
FinalFailIncorrectCltvExpiry error, when the last HTLC of a route (exit
hop) has an expiration height that is deemed too soon by the final
destination of the HTLC.

multi: replace per channel sigPool with global daemon level sigPool
In this commit, we remove the per channel `sigPool` within the
`lnwallet.LightningChannel` struct. With this change, we ensure that as
the number of channels grows, the number of gouroutines idling in the
sigPool stays constant. It's the case that currently on the daemon, most
channels are likely inactive, with only a hand full actually
consistently carrying out channel updates. As a result, this change
should reduce the amount of idle CPU usage, as we have less active
goroutines in select loops.

In order to make this change, the `SigPool` itself has been publicly
exported such that outside callers can make a `SigPool` and pass it into
newly created channels. Since the sig pool now lives outside the
channel, we were also able to do away with the Stop() method on the
channel all together.

Finally, the server is the sub-system that is currently responsible for
managing the `SigPool` within lnd.

htlcswitch+routing: implement expiry_too_far failure
In this commit we add a check to HtlcSatifiesPolicy to verify that the
time lock for the outgoing htlc that is requested in the onion packet
isn't too far in the future.

Without this check, anyone could force an unreasonably long time lock on
the forwarding node.
