lnwallet: mark channel as frozen based on ShimIntent
In this commit, we make the internal channel funding flow aware of
frozen channels. We also update the testSingleFunderReservationWorkflow
method to ensure that the created channels have the proper type bit set.

lnwallet/chanfunding: add new ThawHeight() method to ShimIntent+CannedAssembler
As frozen channels can only be created via the non-default channel
assembler, we extend both the ShimIntent and CannedAssembler to also
accept and expose this new channel status along with the thaw height.

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.

lnwallet: check local commitment sanity when adding HTLC
This commit adds an extra validation step when adding HTLCs. Previously
we would only validate the remote commitment resulting from adding an
HTLC, which in most cases is enough. However, there are situations where
the dustlimits are different, which could lead to the resulting remote
commitment from adding the HTLC being valid, but not the local
commitment.

Now we also validate the local commitment. A test to trigger the case is
added.

lnwallet: state transition from correct node during test, remove panic
The unit test TestNewBreachRetributionSkipsDustHtlcs triggered a state
transition from Bob, even though it was Alice that had added the HTLCs.
This is wrong since it will lead to Bob still owing Alice a commitment,
which is not accounted for in the unit tests.

We add a sanity check that the add heights has been set for all entries
found in the logs, and return an error otherwise. This won't happen
during normal operation, but it does reveal the mistake in the unit
test, which is fixed by making Alice trigger the transition.

In addition we resolve a long standing TODO by removing a (purposeful)
panic in the channel state machine. Old version of lnd had a bug that
could lead to the parent entries being lost during channel restore. A
panic was added to get to the bottom of if.

This is now fixed, so new nodes shouldn't encounter it. However, to be
on the safe side, instead of panicking we return an error back to
gracefully exit the channel state machine.

lnwallet: restore unsigned acked remote updates
This commit updates the channel state machine to
persistently store remote updates that we have received a
signature for, but that we haven't yet included in a commit
signature of our own.

Previously those updates were only stored in memory and
dropped across restarts. This lead to the production of
an invalid signature and channel force closure. The remote
party expects us to include those updates.

lnwallet: fix bug in verifyFundingInputs skip dual funder tests for neutrino
In this commit, we fix a long standing bug within the newly created
`verifyFundingInputs` method. Before this commit, the method would
attempt to derive the pkScript by looking at the last items on the
witness stack, and making a p2wsh output script from that. This is
incorrect as typically non of these scripts will actually be p2wsh, and
instead will be p2wkh. We fix this by using the newly available
`txscript.ComputePkScript` method to derive the proper pkScript.

This resolves an issue w.r.t passing incorrect arguments for all
backends, but an issue still stands for the neutrino backend. As is, we
pass a height hint of zero into the `GetUtxo` method call. With the way
the current utxo scanner is set up for neutrino, this'll cause it to
never find the UTXO, as it takes the height hint as a UTXO birth height,
rather than a lower bound of the birth of the UTXO.

lnwallet/chanfunding: introduce new channel funding abstractions
In this commit, we introduce a series of new abstractions for channel
funding. The end goal is to enable uses cases that construct the funding
transaction externally, eventually handing the funding outpoint to lnd.
An example of such a use case includes channel factories and external
channel funding using a hardware wallet.

We also add a new chanfunding.Assembler meant to allow external channel
funding in contexts similar to how channel factories
can be constructed. With this channel funder, we'll only obtain the
channel point and funding output from it, as this alone is enough to
carry out a funding flow as normal.

chanfunding+lnwallet: move coin selection code into new chanfunding package
In this commit, we make an incremental change to move the existing coin
selection code into a new chanfunding package. In later commits, this
package will grow to serve all the lower level channel funding needs in
the daemon.

htlcswitch+lnwallet: replace updateNeeded by check on channel itself
Instead of tracking local updates in a separate link variable, query
this state from the channel itself.

This commit also fixes the issue where the commit tx was not updated
anymore after a failed first attempt because the revocation window was
closed. Also those pending updates will be taken into account when the
remote party revokes.

htlcswitch: check for signature owed in link
Previously the channel method FullySynced was used to decide whether to
send a new commit sig message. However, it could happen that FullySynced
was false, but that we didn't owe a commitment signature. Instead we
were waiting on the other party to send us a signature. If that
happened, we'd send out an empty commit sig. This commit modifies the
condition that triggers a new commit sig and fixes this deviation from
the spec.

lnwallet: log empty commit sig event
To facilitate the logging, this commit adds a new OweCommitment method.
For the logging, we only need to consider the remote perspective. In a
later commit, we'll also start using the local perspective to support
the decision to send another signature.

chainfee: create new chainfee package extracting fees from lnwallet
In this commit, we create a new chainfee package, that houses all fee
related functionality used within the codebase. The creation of this new
package furthers our long-term goal of extracting functionality from the
bloated `lnwallet` package into new distinct packages. Additionally,
this new packages resolves a class of import cycle that could arise if a
new package that was imported by something in `lnwallet` wanted to use
the existing fee related functions in the prior `lnwallet` package.

multi: convert the existing channeldb.ChannelType uint8 into a bit field
In this commit, we convert the existing `channeldb.ChannelType` type
into a _bit field_. This doesn't require us to change the current
serialization or interpretation or the type as it is, since all the
current defined values us a distinct bit. This PR lays the ground work
for any future changes that may introduce new channel types (like anchor
outputs), and also any changes that may modify the existing invariants
around channels (if we're the initiator, we always have the funding
transaction).
