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.

channeldb: convert settled boolean to state
This commit is a preparation for the addition of new invoice
states. A database migration is not needed because we keep
the same field length and values.

lnwallet: prevent static fee estimator fees from being modified

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.

6e8dd9e00f htlcswitch: verify test are running with "debug" tag
Per team decision all tests should run with "debug" flag.
Makefile updated accordingly.

A developer may still run the test from command line by "go test ...."

The commit protects against this and issue an error if needed.

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.

htlcswitch/link_test: increase fwdpkg gc interval
In this commit, we increase the fwdpkg gc interval
to avoid having it conflict with switch tests that
inspect forwarding packages. The current timeout is
a little too short on travis, and sporadically fails
TestChannelLinkCleanupSpuriousResponses, which was
added recently.

htlcswitch/switch: make local response handling async
This commit moves the logic handling responses to
locally-initiated payments to be asynchronous. The
reordering of operations into handleLocalDispatch
brings a serious performance burden to the switch's
main event loop. However, the at-most once semantics
of circuit map and idempotency of cleanup methods
allows concurrent operations to run in parallel.

Prior to this commit, the async_payments_benchmark
would timeout due to the forcibly serial nature of
the prior design. With this change, there is no
perceptible difference in the benchmark OMM, even
though we've added two extra db calls.

htlcswitch/control_tower: use one db txn for transitions
Composes the new payment status helper methods such that
we only require one db txn per state transition. This
also allows us to remove the exclusive lock from the
control tower, and enable more concurrent requests.
