0407b37fce contractcourt+switch: keep channels with timed-out initiated htlcs.
This commit enables the user to specify he is not interested in
automatically close channels with pending payments that their
corresponding htlcs have timed-out.
By requiring a configurable grace period uptime of our node
before closing such channels, we give a chance to the other node to
properly cancel the htlc and avoid unnecessary on-chain transaction.
In mobile it is very important for the user experience as otherwise
channels will be force closed more frequently.

lnwallet: adding TestMaxAsynchronousHtlcs unit test
Adds a new test which asserts that the new ReceiveHTLC logic can
handle proper commitment overflow calculation in the face of
asynchronous updates.

lnwallet: fixing unit tests to properly handle new receive validation
This commit fixes the TestMaxAcceptedHTLCs, TestMaxPendingAmount,
TestMinHTLC, & TestChanReserve unit tests to pass with the new
ReceiveHTLC logic. Instead of asserting specific failures upon
receiving a new commitment signature, the various assertions were
moved to assert on the error returned from ReceiveHTLC.

lnwallet: call valdiateCommitmentSanity in ReceiveHTLC
This commit checks the commitment sanity when receiving an HTLC so
that if a commitment transaction will overflow from an ADD, it is
caught earlier rather than in ReceiveNewCommitment.

sweep: add exclusive groups
Allows certain sweep inputs to be kept in separate transactions at all
times. This is a preparation for anchor outputs. Before the commitment
tx confirms, there are three potential anchors that can be cpfp'ed. We
want to cpfp them all, but if done in the same transaction, the
transaction would guaranteed to be invalid. Exponential backoff would
eventually get the txes published, but having exclusive groups makes the
process faster.

lnwallet: state transition from correct node during test, remove panic
The unit test TestNewBreachRetributionSkipsDustHtlcs triggered a state
transition from Bob, even though it was Alice that had added the HTLCs.
This is wrong since it will lead to Bob still owing Alice a commitment,
which is not accounted for in the unit tests.

We add a sanity check that the add heights has been set for all entries
found in the logs, and return an error otherwise. This won't happen
during normal operation, but it does reveal the mistake in the unit
test, which is fixed by making Alice trigger the transition.

In addition we resolve a long standing TODO by removing a (purposeful)
panic in the channel state machine. Old version of lnd had a bug that
could lead to the parent entries being lost during channel restore. A
panic was added to get to the bottom of if.

This is now fixed, so new nodes shouldn't encounter it. However, to be
on the safe side, instead of panicking we return an error back to
gracefully exit the channel state machine.

lnd: reload cert data after renewal
After renewing the certificate, the new certificate wasn't actually
loaded and used, causing the old one to be used until lnd was restarted.
This fixes that by reloading it after it has been written.

lnd+cert: recreate TLS files if IPs or DNS changed
This commit makes lnd recreate its TLS certificate if the config's
tlsextradomains or tlsextraips changed. This is useful, since earlier
user would have to manually delete the files to trigger lnd to recreate
them.

To ensure users don't accidentally have their TLS certificate recreated,
we gate it behind a flag --tlsautorefresh that defaults to false.

routing/test: test probability extrapolation
Adds an integrated routing test of probability extrapolation for untried
channels. The larger part of this commit is mock code to simulate the
Lightning Network.

The difference between this test and the existing pathfinding tests, is that
this test focuses on the feedback loop from result interpretation via
mission control updates and probability estimation back to pathfinding.
Improvements like probability extrapolation were previously only
validated by reasoning, while this setup makes it possible to assert the
improvement in a test and guard it for the future.

Updates were always restored with the same log index. This could cause a

elsewhere.

channeldb: replace fetch channels booleans with optional filters
This changes replaces the pending an waiting booleans in fetchChannels
with optional filters which can be more flexibly used. This change
allows filtering of channels without having to reason about the matrix
of possible boolean combinations. A test is added to ensure that the
combinations of these filters act as expected.

htlcswitch: add failure details to incoming failures
This commit adds LinkErrors with failure details to htlcs which fail on
our incoming link. This change is made with the intention of notifying
detailed htlc failure reasons in sendHTLCError. The FailureDetail
interface is implemented on FailureResolutionResults so that they can
directly be used to enrich LinkErrors. sendHtlcError is updated to
take a LinkError in preparation for the addition of a htlcnotifier
which will notify the detail of the error.

htlcswitch: add linkError field to htlcpacket
This commit adds a linkError field to track the value of failures
which occur at our node. This field is set when local payments or
multi hop htlcs fail in the switch or on our outgoing link. This
addition is required for the addition of a htlc notifier which will
notify these failures in handleDownstreamPacket.

The passing of link error to failAddPacket removes the need for an
additional error field, because the link error's failure detail will
contain any additional metadata. In the places where the failure detail
does not cover all the metadata that was previously supplied by addr
err, the error is logged before calling failAddPacket so that this
change does not reduce the amount of information we log.

htlcswitch: replace outgoing failure with interface
Add a FailureDetail interface which allows us have different kinds of

invoices: split resolution result into settle, fail and accept enums
This commit splits the resolution result enum into results divided
by outcome (settled, failed or accepted). This allows us to more
strictly control which resolution results can be used with which
HtlcResolution structs, to prevent the combination of a settle
resolution result with a failure resolution result, for example.

multi: replace htlcResolution with an interface
This commit repalces the htlcResolution struct with an interface.
This interface is implemeted by failure, settle and accept resolution
structs. Only settles and fails are exported because the existing
code that handles htlc resolutions uses a nil resolution to indicate
that a htlc was accepted. The accept resolution is used internally
to report on the resolution result of the accepted htlc, but a nil
resolution is surfaced. Further refactoring of all the functions
that call NotifyExitHopHtlc to handle a htlc accept case (rather than
having a nil check) is required.
