invoices: add TestSpontaneousAmpPayment
Adds a set of test cases that exercise the spontaneous AMP payment flow
with valid and invalid reconstructions, as well as with single and
multiple HTLCs. This also asserts that spontaneous AMP is gated behind
the existing AcceptKeysend flag.

channeldb: make payhash on InvoiceRef optional
Currently we support queries by payHash or payHash+payAddr. For handling
of AMP HTLCs, we only need to support querying by payAddr.

invoices: force MPP payload inclusion for non-keysend payments
In this commit, we move to start rejecting any normal payments that
aren't keysend, if they don't also include the MPP invoice payload. With
this change, we require that some sort of e2e secret (either the payment
addr or the keysend pre-image) is present in a payload before we'll
accept the payment.

The second portion of the commit also updates all current tests in the
package. We kept the base `TestSettleInvoice` test in-tact as it still
exercises some useful behavior. However, we've removed all cases that
allow an overpayment, as the new MPP logic doesn't allow overpayment for
various reasons. In addition to this, some of the returned errors are
slightly different, tho the actual behavior is equivalent.

invoices: optionally garbage collect invoices on the fly
This commit extends invoice garbage collection to also remove invoices
which are canceled when LND is already up and running. When the option
GcCanceledInvoicesOnTheFly is false (default) then invoices are kept and
the behavior is unchanged.

channeldb+invoices: add ScanInvoices and integrate with InvoiceRegistry
This commit adds channeldb.ScanInvoices to scan through all invoices in
the database. The new call will also replace the already existing
channeldb.FetchAllInvoicesWithPaymentHash call in preparation to collect
invoices we'd like to delete and watch for expiry in one scan in later
commits.

invoices: add String() method to failure resolution outcome
In this commit, we add a String() method to the failure resolution
outcome. Without this, logs aren't very useful as the integer version of
the outcome is printed rather than the description.

invoices: optionally hold and auto-cancel keysend payments
Adds a new configuration flag to lnd that will keep keysend payments in
the accepted state. An application can then inspect the payment
parameters and decide whether to settle or cancel.

The on-the-fly inserted keysend invoices get a configurable expiry time.
This is a safeguard in case the application that should decide on the
keysend payments isn't active.

multi: add explicit hodl invoice flag to invoice
Previously it wasn't possible to store a preimage in the invoice
database and signal that a payment should not be settled right away. The
only way to hold a payment was to insert the magic UnknownPreimage value
in the invoice database. This commit introduces a distinct flag to
signal that an invoice is a hold invoice and thereby allows the preimage
to be present in the database already.

Preparation for (key send) hodl invoices for which we already know the
preimage.

invoices/invoiceregistry: properly synchronize backlog
This commit moves the db calls for retrieving add and settle backlogs
outide of the main event loop. All other db operations are performed
outside of the event loop and synchronized via the invoice registry's
mutex, which also synchronizes the order in which events submitted to be
processed.

This resolves various concurrency issues where notifications can be
missed of inconsistent reads against the databse. This is especially
important in this case because we are actually making two separate
database calls.

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.

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.

fabcdf754a invoices: fix slow startup with many expired invoices
This commit intends to fix slow first startup time when there are many
invoices that need to be canceled. The slowdown is caused by a combination
of adding invoices to the expiry watcher one-by-one and slow
cancellation. Due to slow cancellation and the unbuffered channel which
we use to pass invoices to the expiry watcher blocks the registry.
With this fix we'll instead batch add invoices to the expiry watcher and
thereby won't block the registry startup.

invoices: jit insert key send invoices
This commit adds handling code for the key send custom record. If this
record is present and its hash matches the payment hash, invoice
registry will insert a new invoice into the database "just in time". The
subsequent settle flow is unchanged. The newly inserted invoice is
picked up and settled. Notifications will be broadcast as usual.
