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: 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: 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: add new TestForwardingAsymmetricTimeLockPolicies test
In this commit, we add a new test to the switch:
TestForwardingAsymmetricTimeLockPolicies. This test ensures that a link
has two channels, one of which has a greater CLTV delta than the latter,
that a payment will successfully be routed across the channels. Atm, the
test fails (including the fix to hop payload generation included in the
next commit).

Atm, due to the way that we check forwarding policies, we'll reject this
payment as we're attempting to enforce the policy of the incoming link
(cltv delta of 7), instead of that of the outgoing link (cltv delta of
6). As a result, atm, the incoming link checks if (incoming_timeout -
delta < outgoing_timeout). For the values in the test case: 112 - 7 <
106 -> 105 < 106, this check fails. The payload is proper, but the check
itself should be applied at the outgoing hop.

multi: move block epochs dependency from links to switch
In this commit, we move the block height dependency from the links in
the switch to the switch itself. This is possible due to a recent change
on the links no longer depending on the block height to update their
commitment fees.

We'll now only have the switch be alerted of new blocks coming in and
links will retrieve the height from it atomically.

peer+htlcswitch: randomize link commitment fee updates
In this commit, we modify the behavior of links updating their
commitment fees. Rather than attempting to update the commitment fee for
each link every time a new block comes in, we'll use a timer with a
random interval between 10 and 60 minutes for each link to determine
when to update their corresponding commitment fee. This prevents us from
oscillating the fee rate for our various commitment transactions.

link test: add TestChannelLinkWaitForRevocation
This commit adds a test where we trigger a situation which would
previously make the link think it was never in sync, and potentially
create a lot of empty state updates. This would happen if we were
waiting for a revocation, while still receiving updates from the remote.
Since in this case we could not ACK the updates because of the exhausted
revocation window, our local commitchain would extend, while the remote
chain would stall. When we finally got the revocation the local
commitment height would be far larger than the remote, and FullySynced
would return false from that point on.

link test: add TestChannelLinkNoMoreUpdates
This commit adds a new test that makes sure we don't try to send
commitments for states where there are now new updates. Before the
recent change to FullySynced we would do this in this test scenario, as
the local an remote commitment heights would differ.

The test makes the local commitment chain extend by 1 vs the remote,
which would earlier trigger another state update, and checks taht no
such state update is made.

htlcswitch: move link trimming to link start up
In this commit, we fix a race in the set of TestChannelLinkTrimCircuits*
tests. Before this commit, we would trim the circuits in the htlcManager
goroutine. However, this was problematic as the scheduling order of
goroutines isn't predictable. Instead, we'll now trim the circuits in
the Start method.

Additionally, we fix a series of off-by-2 bugs in the tests themselves.

htlcswitch: fix TestUpdateForwardingPolicy
In this commit, we fix the TestUpdateForwardingPolicy test case after
the recent modification in the way we handling validating constraints
within the link. After the recent set of changes, Bob will properly use
his outgoing link to validate the set of fee related constraints rather
than the incoming link. As a result, we need to modify the second
channel link, not the first for the test to still be applicable.

htlcswitch: allow overpaying for incoming payments
In this commit, we relax the constraints on accepting an exit hop
payment a bit. We'll now accept any incoming payment that _at least_
pays the invoice amount. This puts us further inline with the
specification, which recommends that nodes accept overpayment by a
certain margin.

Fixes #1002.

htlcswitch: modify forwarding fee assertion to compare emperical fees
In this commit, we fix a bug that was uncovered by the recent change to
lnwire.MilliSatoshi. Rather than manually compute the diff in fees,
we’ll directly compare the fee that is given against the fee that we
expect.
