lnwallet/btcwallet: remove internal utxoCache
The cache wasn't really serving a purpose as FetchInputInfo isn't known
to be a hot path. Also, with a planned addition of returning the
confirmation status of an output within FetchInputInfo in a later
commit, caching won't be useful as we'll have to go to disk anyway to
determine the confirmation status.

lnwallet: when signing create account if not found
In this commit, we address an edge case that can happen a user rescans
w/ their seed, while retaining their existing `channel.db`. Once they
rescan, if they go to sign for a channel sweep for example, the
commitment key family (actually an account) may not yet have been
created, causing the signing attempt to fail.

We remedy this always creating the account if we go to sign, and the
account isn't found. The change has been structured to make this the
exception, so we'll avoid always needing to do 2 DB hits (check if
account exists, sign), each time we sign.

A new test has been added to exercise this behavior. If the diff from
the `signer.go` file is removed, then the test will fail.

lnwallet/wallet: define SubtractFees for InitFundingReserveMsg
This commit adds a SubtractFees option to the funding request, letting
the caller specify that the fees should be deducted from the funding
amount. This paves the way for letting the funding manager spend up to a
given amount when creating a channel, like the rest of the funds in the
wallet.

bd46491d07 lnwallet: fix key derivation for very first key in family
In this commit, we fix an existing bug that would cause us to be unable
to derive the very first key in a key family if the wallet hadn't
already derived it in the past. This can happen if a user keeps their
same `channel.db`, but restores their wallet resulting in fresh
`wallet.db` state.

This is an existing issue due to the fact that we don't properly
distinguish between an empty key locator, and the very first key in a
`KeyFamily`: `(0, 0)`. Atm, `KeyLoactor{0, 0}.IsEmpty() == True`,
causing us to be unable to retrieve this key in certain cases since we
fall through and attempt address based derivation.

In order to remedy this, we add a new special case (until we upgrade
`KeyLoactor` formats, but needed for legacy reasons) to _try_ a regular
`KeyLoactor` based derivation if we fail to derive via address, and this
is an "empty" key loc. This has been tested in the field and shown to
work, with the one downside that in this "hot swap restoration" case,
we'll hit the database twice to derive the key.

eaa043f585 lnwallet/btcwallet: use relay fee not tx fee rate for dust check
In this commit we fix a hidden bug in the transaction creating logic
that was only manifested recently due to higher fees on Bitcoin's
mainnet. Before this commit, we would use the target fee rate to
determine if an output was dust or not. However, this is incorrect, as
instead the relay fee should be used as this matches the policy checks
widely deployed in Bitcoin full node today.

To fix this issue we now properly use the relay fee when computing dust.
This fixes the issue for the `EstimateFee` call, but the `SendOutputs`
call also has a similar issue. However, this must be fixed within
`btcwallet` itself, so it has been left out of this commit

Fixes #3217.

5f0fad85be multi: address lingering TODO by no longer wiping out local HTLCs on remote close
In this commit, we fix a lingering TOOD statement in the channel arb.
Before this commitment, we would simply wipe our our local HTLC set of
the HTLC set that was on the remote commitment transaction on force
close. This was incorrect as if our commitment transaction had an HTLC
that the remote commitment didn't, then we would fail to cancel that
back, and cause both channels to time out on chain.

In order to remedy this, we introduce a new `HtlcSetKey` struct to track
all 3 possible in-flight set of HTLCs: ours, theirs, and their pending.

We also we start to tack on additional data to all the unilateral close
messages we send to subscribers. This new data is the CommitSet, or the
set of valid commitments at channel closure time. This new information
will be used by the channel arb in an upcoming commit to ensure it will
cancel back HTLCs in the case of split commitment state.

Finally, we start to thread through an optional *CommitSet to the
advanceState method. This additional information will give the channel
arb addition information it needs to ensure it properly cancels back
HTLCs that are about to time out or may time out depending on which
commitment is played.

Within the htlcswitch pakage, we modify the `SignNextCommitment` method
to return the new set of pending HTLCs for the remote party's commitment
transaction and `ReceiveRevocation` to return the latest set of
commitment transactions on the remote party's commitment as well. This
is a preparatory change which is part of a larger change to address a
lingering TODO in the cnct.

Additionally, rather than just send of the set of HTLCs after the we
revoke, we'll also send of the set of HTLCs after the remote party
revokes, and we create a pending commitment state for it.

4944eb3e54 lnwallet: add implementation of WebApiFeeSource for external APIs
This enables users to specify an external API for fee estimation.
The API is expected to return fees in the JSON format:
`{
	fee_by_block_target: {
	   a: x,
	   b: y,
	   ...
	   c: z
        }
 }`
 where a, b, c are block targets and x, y, z are fees in sat/kb.
 Note that a, b, c need not be contiguous.

lnwallet: send invalid commitment secret if restored chan in ChanSyncMsg
In this commit, we modify the `ChanSyncMsg` to send an invalid
commitment secret in `ChanSyncMsg`. We do this in order to force the
remote party to force close off-chain, if we're restoring a channel from
scratch and we never had any state updates within the channel. We need
to do this, as otherwise the remote party will think we can resume as
they're able to verify their own commit secret for state zero.
