multi: add labels to lnd native transactions
Follow up labelling of external transactions with labels for the
transaction types we create within lnd. Since these labels will live
a life of string matching, a version number and rigid format is added
so that string matching is less painful. We start out with channel ID,
where available, and a transaction "type". External labels, added in a
previous PR, are not updated to this new versioned label because they
are not lnd-initiated transactions. Label matching can check this case,
then check for a version number.

contractcourt: persist remote outgoing htlc claim outcome on disk
When a remote peer claims one of our outgoing htlcs on chain, we do
not care whether they claimed with multiple stages. We simply store
the claim outgome then forget the resolver.

contractcourt: persist timed out incoming htlc resolver reports
Incoming htlcs that are timed out or failed (invalid htlc or invoice
condition not met), save a single on chain resolution because we don't
need to take any actions on them ourselves (we don't need to worry
about 2 stage claims since this is the success path for our peer).

contractcourt: add resolver report function to ContractReport
Our current set of reports contain much of the information we will
need to persist contract resolutions. We add a function to create
resolver reports from our exiting set of resolutions.

multi: add resolver reports to Checkpoint
To allow us to write the outcome of our resolver to disk, we add
optional resolver reports to the CheckPoint function. Variadic params
are used because some checkpoints may have no reports (when the resolver
is not yet complete) and some may have two (in the case of a two stage
resolution).

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.

multi: update WalletController PublishTransaction to include label
Add label parameter to PublishTransaction in WalletController
interface. A labels package is added to store generic labels that are
used for the different types of transactions that are published by lnd.

To keep commit size down, the two endpoints that require a label
parameter be passed down have a todo added, which will be removed in
subsequent commits.

2110bfa40b contractcourt: test sweep of locally breached commit tx
This adds a test to the commit sweeper resolver to ensure it behaves
properly if the local node breaches a channel.

In this situation the remote party is expected to sweep the breached
output to itself and therefore the local party won't be able to recover
any funds.

d71a4ee033 contractcourt+itest: fix lingering pending channel after breach
This fixes an issue where the contract court could leave a completely
swept commit tx unresolved if it was swept by the remote party.

This could happen if (our) commit tx just published was actually a
previously revoked state, in which case the remote party would claim the
funds via a justice transaction.

This manifested itself in the testRevokedCloseRetribution integration
test where at the end of the test Bob was left with a pending channel
that never resolved itself.

contractcourt: add additional logging of commitments at play
In this commit, we add some additional logging of the commitments at
play when we detect a channel closure on-chain. This should help to
debug things more in the future as we don't log the full commitments
anywhere.  We also now also print the type of commitment as well, as a
follow up from the recent anchor outputs work. In the near future, as we
implement a dynamic commitments update protocol, always logging the
commitment type as well will likely be useful for debugging purposes.

cnct: resolve anchors post-confirmation
Sweeping anchors and being able to bump the fee was already added in a
previous commit. This commit extends anchor sweeping with an anchor
resolver object that becomes active after the commitment tx confirms.
At that point, the anchors do not serve the purpose of getting the
commitment tranaction confirmed anymore. It is however still possible to
reclaim some of their value if using a low fee rate.

cnct: do not ignore resolver reports after resolution
Preparation for anchor resolver. The recovered anchor amount should
still be included in the pending channel report even after it has been
resolved.

This also fixes an existing bug that in some cases caused the recovered
amount from an htlc resolver not to be included in the total.

cnct: pre-confirmation anchor sweep
Start anchor sweep attempts immediately after the commitment transaction
has been published. This makes the anchor known to the sweeper and
allows the user to bump the fee on it to get their commitment
transaction confirmed in case the fee committed too is insufficient for
timely confirmation.

contractcourt/commit_sweep_resolver: set sweep witness type based on witness script
We use the fact that we can tell whether the commit is local or remote
by inspecting the witness script. We cannot use the maturity delay
anymore, as we can have delayed to_remote outputs also now.

channeldb: store close initiator status
This commit adds two new channel statuses which indicate the party that
initatited closing the channel. These statuses are set in conjunction
with the existing commit broadcast status so that we do not need to
migrate existing logic to handle multiple types of closes. This status
is set for locally initiated force closes in this commit because they
follow a similar pattern to cooparative closes, marking the commitment
broadcast then proceeding with tx broadcast. Remote force closes are
added in the following commit, as they are handled differently.
