routing: refactor update payment state tests
This commit refactors the resumePayment to extract some logics back to
paymentState so that the code is more testable. It also adds unit tests
for paymentState, and breaks the original MPPayment tests into independent tests
so that it's easier to maintain and debug. All the new tests are built
using mock so that the control flow is eaiser to setup and change.

routing: rename mock structs to make them obsolete
This commit renames the mock structs by appending Old in their names. In
doing so the old tests stay unchanged and new mock structs can be added
in the following commit.

routing: fix TestSendPaymentErrorRepeatedFeeInsufficient
The simulated error returned was rejected due to signature failure,
and didn't simulate correctly the insufficient fees error as
intended. Fix error by including correct signature.

routing: add new error for failed funding tx validation
In this commit we add a new error for when we fail to validate the
funding transaction (invalid script, etc) and mark it as a zombie like
the other failed validation cases.

routing: add chans rejected due to failed chain validation to zombie index
In this commit, we start to add any channels that fail the normal chain
validation to the zombie index. With this change, we'll ensure that we
won't continue to re-process the same set of spent channels over and
over again.

Fixes #5191.

routing: use Identifier in place of PaymentHash
Since we want to support AMP payment using a different unique payment
identifier (AMP payments don't go to one specific hash), we change the
nomenclature to be Identifier instead of PaymentHash.

routing: add strict zombie pruning as a config level param
In this commit, we add strict zombie pruning as a config level param.
This allow us to add the option for those that want a tighter graph, and
not change the default composition of the channel graph for most users
over night.

In addition, we expand the test case slightly by testing that the self
node won't be pruned, but also that if there's a node with only a single
known stale edge, then both variants will prune that edge.

routing: delay initial zombie prune by 30 sec
Since zombie pruning can be very slow on some devices (e.g. mobile) it
would stall lnd startup. Since it is not essential for pruning to be
finished for lnd to be functional, we instead delay the initial prune by
30 seconds.

Note that we could also wait for the graphPruneInterval to tick, but
since this is by default 2 hours, it is unlikely that a mobile app will
ever be open that long.

routing: avoid modifying AssumeChannelValid in unit tests
This produces a race condition when reading AssumeChannelValid from a
different goroutine. Instead we isolate the test cases and initial
AssumeChannelValid properly.

router: move self node out of config
We are going to use the config struct to allow getting and setting

is not something we want to change, so we move it out for better
separation.

routing+lnrpc: extend BuildRoute to accept raw payAddr
In this commit, we extend the `BuildRoute` method and RPC on the router
sub-server to accept a raw payment address which will be included as
part of an MPP payload for the finla hop. This change actually also
allows users to craft their own MPP paths using BuildRoute+SendToRoute.
Our primary goal however, was to fix some broken itests since we now
require the payAddr to be present for ALL payments other than key send
payments.

multi: enforce routing.MinCLTVDelta=18 for invoices + chanupd
This commit clamps all user-chosen CLTVs in LND to be at least 18, which
is the new conservative value used in the sepc. This minimum is applied
uniformly to forwarding CLTV deltas (via channel updates) as well as
final CLTV deltas for new invoices.

routing tests: move TestRouterPaymentStateMachine to own file
(almost) PURE CODE MOVE

case _ <- channel:

case <- channel:

to please the linter.

routing/payment_lifecycle: return recorded errors
In preparation for MPP we return the terminal errors recorded with the
control tower. The reason is that we cannot return immediately when a
shard fails for MPP, since there might be more shards in flight that we
must wait for. For that reason we instead mark the payment failed in the
control tower, then return this error when we inspect the payment,
seeing it has been failed and there are no shards in flight.

routing: remove errNoRoute and lastError
Now that SendToRoute is no longer using the payment lifecycle, we
remove the error structs and vars used to cache the last encountered
error. For SendToRoute this will now be returned directly after a shard
has failed.

For SendPayment this means that the last error encountered durinng
pathfinding no longer will be returned. All errors encounterd can
instead be inspected from the HTLC list.

routing/router_test: remove preimage overwrite
The test case's preimage was (mistakenly) overwritten after crafting the
lightning payment, causing the parts of the testcases use the same
preimage causing problems when we are using the payment hash and
preimage in the mock control tower to distinguish paymennts.

htlcswitch: add ClearTextError interface
This commit adds a ClearTextError interface
which is implemented by non-opaque errors that
we know the underlying wire failure message for.
This interface is implemented by ForwardingErrors,
because we can fully decrypt the onion blob to
obtain the underlying failure reason. This interface
will also be implemented by errors which originate
at our node in following commits, because we know
the failure reason when we fail the htlc.

The lnwire interface is un-embedded in the
ForwardingError struct in favour of implementing
this interface. This change is made to protect
against accidental passing of a ForwardingError
to the wire, where the embedded FailureMessage
interface will present as wire failure but
will not serialize properly.

routing+routerrpc: improve prob. estimation for untried connections
This commit changes mission control to partially base the estimated
probability for untried connections on historical results obtained in
previous payment attempts. This incentivizes routing nodes to keep all

routing+routerrpc: take max cltv limit into account within path finding
With the introduction of the max CLTV limit parameter, nodes are able to
reject HTLCs that exceed it. This should also be applied to path
finding, otherwise HTLCs crafted by the same node that exceed it never
left the switch. This wasn't a big deal since the previous max CLTV
limit was ~5000 blocks. Once it was lowered to 1008, the issue became
more apparent. Therefore, all of our path finding attempts now have a
restriction of said limit in in order to properly carry out HTLCs to the
network.
