htlcswitch/switch: permit link shutdown mid-forwarding
In this commit, we thread through a link's quit channel into
routeAsync, the primary helper method allowing links to send
htlcPackets through the switch. This is intended to remove
deadlocks from happening, where the link is synchronously
blocking on forwarding packets to the switch, but also
needs to shutdown.

htlcswitch/link_test: adds TestChannelLinkShutdownDuringForward
This commit adds a test that verifies Stop does not block
if the link is concurrently forwarding incoming Adds to
the switch. This test fails prior to the commits that
thread through the link's quit channel.

htlcswitch/link_test: removes unnecessary WaitForShutdown
The new RemoveLink method blocks until the link has
been fully stopped, so we no longer need to wait
for it explicitly.

htlcswitch/link: reusable BatchTicker
This commit modifies the default BatchTicker
implementation such that it will generate a
new ticker with each call to Start(). This
allows us to create a new ticker after
releasing an old one due to the batch
being empty.

htlcswitch/link: conditional batch ticker
In this commit, we prevent the htlcManager from
being woken up by the batchTicker when there is no
work to be done. Profiling has shown a significant
portion of CPU time idling, since the batch ticker
endlessly demands resources. We resolve this by only
selecting on the batch ticker when we have a
non-empty batch of downstream packets from the
switch.

htlcswitch/link: send FailFinalExpiryTooSoon from exit hop
This commit corrects our exit hop logic to return
FailFinalExpiryTooSoon if the following check is true:
   pd.Timeout-expiryGraceDelta <= heightNow

Previously we returned FailFinalIncorrectCltvExpiry, which
should only be returned if the packet was misconstructed.

htlcswitch: modify the InvoiceDatabase interface to allow specifying final payment amt
In this commit, we modify the InvoiceDatabase slightly to allow the link
to record what the final payment about for an invoice was. It may be the
case that the invoice actually had no specified value, or that the payer
paid more than necessary. As a result, it's important that our on-disk
records properly reflect this.

To fix this issue, the SettleInvoice method now also accepts the final
amount paid.

Fixes #856.

htlcswitch/link: correct bias in fee update backoff
This commit corrects the distribution used to
schedule a link's randomized backoff for fee
updates. Currently, our algorithm biases the
lowest value in the range, with probability
equal to lower/upper, or the ratio of the lower
bound to the upper. This distribution is skewed
more heavily as lower approaches upper.

The solution is to sample a random value in the
range upper-lower, then add this to our lower
bound. The effect is a uniformly distributed
timeout in [lower, upper).

htlcswitch: obtain the min final CLTV delta directly from the InvoiceDatabase
In this commit, we modify the existing logic that would attempt to read
the min CLTV information from the invoice directly. With this route, we
avoid any sort of DB index modifications, as this information is already
stored within the payment request, which is already available to the
outside callers. By modifying the InvoiceDatabase interface, we avoid
having to make the switch aware of what the "primary" chain is.

htlcswitch/decayedlog_test: fix bug in gc unit test
This commit fixes a bug in the
TestDecayedLogPersistentGarbageCollector unit test.
The test generates a second hash prefix, which is never
added to the log, and used to query for the final
existence check. This commit reverts the behavior so
that the same hash prefix is used throughout the test.

htlcswitch: use the delta within the time lock, not the default policy at exit node
In this commit, we fix a lingering bug within the link when we're the
exit node for a particular payment. Before this commit, we would assert
that the invoice gives us enough of a delta based on our current routing
policy. However, if the invoice was generated with a lower delta, or
we've changed from the default routing policy, then this would case us
to fail back any payments sent to us.

We fix this by instead using the newly available final CLTV delta
information within the extracted invoice.

Fixes #1431.
