multi: add relative thaw height interpretation
This is useful when we wish to have a channel frozen for a specific
amount of blocks after its confirmation. This could also be done with an
absolute thaw height, but it does not suit cases where a strict block
delta needs to be enforced, as it's not possible to know for certain
when a channel will be included in the chain. To work around this, we
add a relative interpretation of the field, where if its value is below
500,000, then it's interpreted as a relative height. This approach
allows us to prevent further database modifications to account for a
relative thaw height.

lnwallet/test: reproduce test vectors in commit and htlc tx test
This commit changes the verification of our code against the spec test
vectors to use a more black box approach. It exercises the channel state
machine via its external interface as much as possible, making this test
more robust. A consequence of this is that the test now runs from the
'root' data from which the test vectors are also derived, meaning that
more code is covered too.

Running from the root data is also a preparation for _producing_ test
vectors for the new anchor commitment format. This will be a matter of
changing the channel type and recording the produced commitment and htlc
txes.

Previously the success transaction was skipped during verification. With
this commit, the proper preimage insertion is carried out, allowing the
success tx to be checked too.

2d68a64a5b chancloser: new package for cooperative channel closure
Introduces a new chancloser package which exposes a ChanCloser
struct that handles the cooperative channel closure negotiation
and is meant to replace chancloser.go in the lnd package. Updates
all references to chancloser.go to instead use chancloser package.

btcwallet: ensure output isn't locked by in-memory impl in LeaseOutput
The current implementation of LeaseOutput already checked whether the
output had already been leased by the persisted implementation, but not
the in-memory one used by lnd internally. Without this check, we could
potentially end up with a double spend error if lnd acquired the UTXO
internally before the LeaseOutput call.

Add label parameter to PublishTransaction in WalletController
interface. A labels package is added to store generic labels that are

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.

lnwallet/channel: enforce absolute fee floor of 250 sat/kw
This enforces the _actualized_ fee rate of the  commitment transaction,
rather than the fee floor used for estimation. The new value of 250
sat/kw corresponds to 1 sat/byte, rather than 253 which is only rounded
up during estimation to account for the fact that BOLT 3 rounds down to
the nearest satoshi and that the vbyte fee estimation is lossy.

Previously we would incorrectly fail to sign the next commitment even
though the fee was technically high enough. Restarting with this commit
should solve the issue as long as the channel hasn't already gone to
chain.

input: introduce Signature iface
This commit introduces the Signature interface which will be used by our
witness construction methods instead of passing in raw byte slices. This
will be used later to inject various kinds of mock signatures, e.g.
73-byte signatures for simulating worst-case witness weight.

lnwallet/channel_test: assert commit sorting of commit diff htlcs
This commit adds a test to exercise that HTLC signatures are sent in the
correct order, i.e. they match the sorting of the HTLC outputs on the
commitment after applying BOLT 3's BIP69+CLTV sort.

lnwallet/channel: tie-break HTLCs by cltv when locating
This commit fixes #4118 by properly sorting the HTLC signatures sent
over the wire to match the BOLT3 BIP69+CLTV sorting of the commitment
outputs.

To do so, we expose the slice of cltv deltas for HTLCs on the unsigned
commitment after applying the commitment sorting. This will be used to
locate the proper output index, as the CLTV serves as a tie breaker
between HTLCs that otherwise have the same payment hash and amount.

Note that #3412 fixed the issue partially by ensuring the commitment was
constructed properly (and the second-level prev outpoint's txid was
correct), but failed to address that the HTLC signatures were still sent
out in the incorrect order. With this, we pass the test case introduce
in the next commit.

lnwallet/channel: populate htlc indexes from disk commit
We currently write each HTLCs OutputIndex to disk, but we don't use it
when restoring. The restoration is modified to use these directly, since
we will have lost access to the sorting of CLTVs after the initial
signing process.
