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/link_test: update Bandwidth tests
This commit updates the tests for checking a links Bandwidth()
calculation, after the change that made us use the remoteACKedIndex
instead of the logIndex when calculating it. The main result of this
change is that we never consider incoming updates before they are
acked, when calculating the bandwidth. This is because this was
inconsistent with the state we actually end up signing later on.

htlcswitch: reject duplicate payments to same invoice
In this commit, we modify the way the link handles HTLC’s that it
detects is destined for itself. Before this commit if a payment hash
came across for an invoice we’d already settled, then we’d gladly
accept the payment _again_. As we’d like to enforce the norm that an
invoice is NEVER to be used twice, this commit modifies that behavior
to instead reject an incoming payment that attempts to re-use an
invoice.

Fixes #560.

317b44e220 lnwallet: Change channel update methods to accept HTLC ID.
Previously, some methods on a LightningChannel like SettleHTLC and
FailHTLC would identify HTLCs by payment hash. This would not always
work correctly if there are multiple HTLCs with the same payment hash,
so instead we change these methods to identify HTLCs by their unique
identifiers instead.

htlcswitch: within link, with each new block, check to see if commit fee should change
In this commit we add a new case to the main select statement within a
channel link. This select statement will serve as a Sipping Bird which
will check the network fee rate (as returned by the fee estimator) and
compare that to the fee on the commitment transaction. Using the
shouldAdjustCommitFee function, we determine if we should update the
commitment fee. If so, then we’ll send an UpdateFee message and also
trigger a new commitment update.

We also add a new unit test: TestChannelLinkUpdateCommitFee to ensure
that we update the fee accordingly if the fee increases or decreases by
a large portion.
