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).

config: only normalize and resolve tor DNS host if it has changed
In the event that the default Tor DNS host wouldn't resolve, it would
prevent `lnd` from starting due to the failed lookup. This should fail
silently as it's only crucial during bootstrapping. However, if the user
has explicitly modified this, we should let them know of the error
immediately.

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.

lnd: only print shutdown message if logs are initialized
In this commit, we fix a slight bug recently introduced by the addition
of the new signal package. As we now use a regular defer for many
actions, it may be possible that the logs aren't yet initialized (for
example, lnd -h), which can cause a panic if the shutdown procedure goes
to log before the logs have been initialized.

b52796749f routing: new weight function
In this commit, a new weight function is introduced. This will create a
meaningful effect of time lock on route selection. Also, removes the
squaring of the fee term. This led to suboptimal routes.

Unit test added that covers the weight function and asserts that the
lowest fee route is indeed returned.

d4471878df routing: fix route fee calculation and channel capacity check
This commit fixes the logic inside the newRoute function to
address the following problems:

- Fee calculation for a hop does not include the fee that needs
  to be paid to the next hop.

- The incoming channel capacity "sanity" check does not include
  the fee to be paid to the current hop.

70ff4414d9 lnd_test: use different fee policy in multi hop payment test
This change makes the test more sensitive to bugs than a route
with nodes that all enforce the same fee policy.

In addition to that, the fee has been increased to a level
at which potential problems with improper fee calculation
become detectable (and not disappear in rounding).

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.

8dcfeeaef5 channeldb: explicitly store the FinalCltvDelta within the ContractTerm struct
In this commit, we move to explicitly storing a bit more information
within the invoice. Currently this information is already stored in the
payment request, but by storing it at this level, callers that may not
be in the state to fully decode a payment request can obtain this data.

We avoid a database migration by appending this data to the end of an
invoice. When decoding, we'll try to read out this extra information,
and simply return what we have if it isn't found.

routing: fix incorrect expiry values in spec_example.json
In this commit, we fix the incorrect expiry values in the
spec_example.json test file. Many of the time locks were incorrect which
allowed bugs within the path finding logic related to CLTV deltas to go
un-detected.

routing: fix bug in newRoute, use time lock delta of prior hop, not current
In this commit, we fix an existing bug in the newRoute method. Before
this commit we would use the time lock delta of the current hop to
compute the outgoing time lock for the current hop. This is incorrect as
the time lock delta of the _outgoing_ hop should be used, as this is
what we're paying for "transit" on. This is a bug left over from when we
switched the meaning of the CLTV delta on the ChannelUpdate message
sometime last year.

The fix is simple: use the CLTV delta of the prior (later in the route)
hop.
