multi: add height-based invoice expiry
This commit adds height-based invoice expiry for hodl invoices
that have active htlcs. This allows us to cancel our intentionally
held htlcs before channels are force closed. We only add this for
hodl invoices because we expect regular invoices to automatically
be resolved.

We still keep hodl invoices in the time-based expiry queue,
because we want to expire open invoices that reach their timeout
before any htlcs are added. Since htlcs are added after the
invoice is created, we add new htlcs as they arrive in the
invoice registry. In this commit, we allow adding of duplicate
entries for an invoice to be added to the expiry queue as each
htlc arrives to keep implementation simple. Our cancellation
logic can already handle the case where an entry is already
canceled, so this is ok.

config: expose distinct accept-amp flag
This mirrors the accept-keysend flag, but also permits users to
eventually toggle off keysend separately from AMP.

3223df74e5 channelnotifier+discover+invoices: return error in Stop functions
In order to be consistent with other sub systems an error is now
returned from the Stop functions.
This also allows writing a generic cleanup mechanism to stop all
sub systems in case of a failure.

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.

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.
