switch+router+server: move NextPaymentID to router
This commit moves the responsibility of generating a unique payment ID
from the switch to the router. This will make it easier for the router
to keep track of which HTLCs were successfully forwarded onto the
network, as it can query the switch for existing HTLCs as long as the
paymentIDs are kept.

The router is expected to maintain a map from paymentHash->paymentID,
such that they can be replayed on restart. This also lets the router
check the status of a sent payment after a restart, by querying the
switch for the paymentID in question.

routing/router: define PaymentAttemptDispatcher interface
The switch satisfies this interface, and makes it easy to mock the send
method from the router.

cnct+htlcswitch+invoices: move invoice parameter check out of link
This commit is the final step in making the link unaware of invoices. It
now purely offers the htlc to the invoice registry and follows
instructions from the invoice registry about how and when to respond to
the htlc.

The change also fixes a bug where upon restart, hodl htlcs were
subjected to the invoice minimum cltv delta requirement again. If the
block height has increased in the mean while, the htlc would be canceled
back.

Furthermore the invoice registry interaction is aligned between link and
contract resolvers.

lnd_test: move chain claim tests to separate files
This commit splits out several integration tests that will be modified
in a follow up commit to separate files. The current lnd_test.go file is
10k+ loc which makes it harder to handle by tools and it isn't good for
overview either.

witness_beacon: do not look up invoice preimages
This commit isolates preimages of forwarded htlcs from invoice
preimages. The reason to do this is to prevent the incoming contest
resolver from settling exit hop htlcs for which the invoice isn't marked
as settled.

cnct: be stricter about matching preimages
The former tryApplyPreimage function silently ignored invalid preimages.
This could mask potential bugs. This commit makes the logic stricter and
generates an error in case an unexpected mismatch occurs.

cnct: do not depend on ChainIO in incoming contest resolver
New behaviour of the chain notifier to always send the current block
immediately after registration takes away the need to make a separate
GetBestBlock call on ChainIO.

channel+cnct: remove preimage from channel and resolution
Now that the success resolver preimage field is always populated by the
incoming contest resolver, preimage lookups earlier in the
process (channel and channel arbitrator) can mostly be removed.

cnct: always create incoming contest resolver
One of the first things the incoming contest resolver does is checking
if the preimage is available and if it is, convert itself into a success
resolver.

This behaviour makes it unnecessary to already determine earlier in the
process whether an incoming contest or a success resolver is needed.

By having all incoming htlcs go through the incoming contest resolver,
the number of execution paths is reduced and it becomes easier to
ascertain that the implemented logic is correct.

The only functional change in this commit is that a forwarded htlc for
which is the preimage is known, is no longer settled when the htlc is
already expired. Previously a success resolver would be instantiated
directly, skipping the expiry height check.

This created a risk that the success resolver would never finish,
because an expired htlc could already have been swept by the remote
party and there is no detection of this remote spend in the success
resolver currently.

With the new change, the general direction that an expired htlc
shouldn't be settled and instead given up on is implemented more
consistently.

This commit prepares for fixing edges cases related to hodl
invoice on-chain resolution.

SubscribeSingleInvoiceRequest that contains only the RHash field.

routing/router: break rescans on router quit
This commit reevaluates the router's quit channel between each block
during the initial call to syncGraphWithChain, which, in the worst case,
may have to scan several thousand blocks on startup if the node has not
been active for some time. Without this, attempting to stop the daemon
will not exit until the rescan has completed, which for certain backends
could be several hours.

peer: break sendMessage on server quit
This commit modifies sendMessage to break on the server's quit channel,
which allows synchronous callers of SendMessage or SendLazyMessage to
receive an error during server shutdown which can be independent of a
particular peer's shutdown.

As of https://github.com/lightningnetwork/lnd/pull/2916, all replies
made by gossip syncers were modified to be synchronous. In certain
cases, This would prevent the syncers from shutting down promptly, as
they would try to offload a batch a of messages that could not be
aborted. Now, an error will be propagated back to the caller, allowing
them to detect the error condition, and reevaluate their own quit
signals, releasing any waitgrouped goroutines and permitting a quick
shutdown.
