htlcswitch: hodl invoice
This commit modifies the invoice registry to handle invoices for which
the preimage is not known yet (hodl invoices). In that case, the
resolution channel passed in from links and resolvers is stored until we
either learn the preimage or want to cancel the htlc.

htlcswitch: abtract invoice from link
This commit detaches signaling the invoice registry that an htlc was
locked in from the actually settling of the htlc.

It is a preparation for hodl invoices.

htlcswitch/test: use real invoice registry with temp db as mock
In further commits the behaviour of invoice registry becomes more
intrinsically connected to the link. This commit prepares for that by
allowing link and registry to be tested as a single unit.

htlcswitch/test: move preimage cache to server level
In this commit the preimage cache is instantiated on the mock server
level where it belongs. Previously it was a cache shared across all mock
servers.

multi: make AddPreimage variadic, optimistically compute key
In this commit, we modify the WitnessCache's
AddPreimage method to accept a variadic number
of preimages. This enables callers to batch
preimage writes in performance critical areas
of the codebase, e.g. the htlcswitch.

Additionally, we lift the computation of the
witnesses' keys outside of the db transaction.
This saves us from having to do hashing inside
and blocking other callers, and limits extraneous
blocking at the call site.

invoices: use lntypes.Hash and lntypes.Preimage
Previously chainhash.Hash was used, which converts to/from string in

This commit is a step to split the lnwallet package. It puts the Input

htlcswitch/mock: drop messages if link is not online
In this commit, we modify the readHandler w/in
the mock peer to drop messages if it is unable
to find the target link. This has led to observed
race conditions related to removing a link and still
attempting to deliver messages. By removing this,
the readHandler shouldn't fail the test as a result.

htlcswitch: modify the InvoiceDatabase interface to allow specifying final payment amt
In this commit, we modify the InvoiceDatabase slightly to allow the link
to record what the final payment about for an invoice was. It may be the
case that the invoice actually had no specified value, or that the payer
paid more than necessary. As a result, it's important that our on-disk
records properly reflect this.

To fix this issue, the SettleInvoice method now also accepts the final
amount paid.

Fixes #856.

htlcswitch: obtain the min final CLTV delta directly from the InvoiceDatabase
In this commit, we modify the existing logic that would attempt to read
the min CLTV information from the invoice directly. With this route, we
avoid any sort of DB index modifications, as this information is already
stored within the payment request, which is already available to the
outside callers. By modifying the InvoiceDatabase interface, we avoid
having to make the switch aware of what the "primary" chain is.

htlcswitch: extend the HtlcSatifiesPolicy to also accept timelock/height info
In this commit, we extend the existing HtlcSatifiesPolicy method to also
accept timelock and height information. This is required as an upcoming
commit will fix an existing bug in the forwarding logic wherein we use
the time lock policies of the incoming node rather than that of the
outgoing node.

multi: move block epochs dependency from links to switch
In this commit, we move the block height dependency from the links in
the switch to the switch itself. This is possible due to a recent change
on the links no longer depending on the block height to update their
commitment fees.

We'll now only have the switch be alerted of new blocks coming in and
links will retrieve the height from it atomically.

htlcswitch: add new ticker in switch to batch log forwarding events
In this commit, we extend the switch as is, to record details
concerning settled payment circuits. To do this, we introduce a new
interface to the package: the ForwardingLog. This is a tiny interface
that simply lets us abstract away the details of the storage backing of
the forwarding log.

Each time we receive a successful HTLC settle, we’ll log the full
details (chans, fees, time) as a pending forwarding log entry. Every 15
seconds, we’ll then batch flush out these entries to disk. When we’re
exiting, we’ll try to flush out all entries to ensure everything gets
recorded to disk.
