lnwallet: within validateCommitmentSanity check for balance underflow
In this commit, we add an additional check within
validateCommitmentSanity due to the recent change to unsigned integers
for peer balances in the channel state machine. If after evaluation
(just applying HTLC updates), the balances are negative, then we’ll
return ErrBelowChanReserve.

lnwallet: if the initiator is unable to pay fees, then consume their entire output
In this commit, we add logic to account for an edge case in the
protocol. If they initiator if unable to pay the fees for a commitment,
then their *entire* output is meant to go to fees. The recent change to
properly interpret balances as unsigned integers (within the protocol)
let to the discovery of this missed edge case.

lnwallet: update interface tests to account for recent lnwire.MilliSatoshi change
lnwire.MilliSatoshi is now a signed integer, as a result, we’ll return
a different error if our balances go to negative due to the inability
to pay a the set fee.

lnwallet: in NewChannelReservation ensure commit fees are payable
In this commit, we fix a bug introduced by the recent change of
lnwire.MilliSatoshi to be an unsigned integer. After this change an
integer underflow was left undetected, as a result we’ll now
momentarily cast to a signed integer in order to ensure that both sides
can pay the proper fee.

lnwallet/btcwallet: grab best header timestamp directly from wallet
In this commit, we modify the way we obtain the current best header
timestamp. In doing this, we fix an intermittent flake that would pop
up at times on the integration tests. This could occur as if the wallet
was lagging behind the chain backend for a re-org, then a hash that the
backend knew of, may not be known by the wallet.

To remedy this, we’ll take advantage of a recent change to btcwallet to
actually include the timestamp in its sync state.

lnwallet: remove p2pkh as an address type, wallet is now pure segwit
In this commit, we modify the mechanics of the wallet to only allow
derivation of segwit-like addresses. Additionally, the ConfirmedBalance
method on the WalletController now only has a single argument, as it’s
assumed that the wallet is itself only concerned with segwit outputs.

lnwallet: modify the way we derive revocation roots to be deterministic
In this commit, we modify the way we generate the secrets for
revocation roots to be fully deterministic. Rather than use a special
key and derive all sub-roots from that (mixing in some “salts”), we’ll
use the proper keychain.KeyFamily instead. This ensures that given a
static description of the channel, we’re able to re-derive our
revocation root properly.

lnwallet: update the SignDescriptor struct to use keychain.KeyDescriptor
In this commit, we update the SignDescriptor struct to instead use the
keychain.KeyDescriptor struct inplace of a raw public key. We do this
as this allows for a recovery mode, where the caller doesn’t know what
key was used exactly, but remembers the precise KeyDescriptor. A
stateless signer is still able to re-derive the proper key, as it’s
given the full path.

lnwallet/btcwallet: update implementation to account for recent API changes
The new version of the internal core of btcwallet now uses KeyScopes
rather than address types to derive particular addresses. As a result,
in this commit, we update our API usage to ensure that proper addresses
are still derived.

lnwallet: remove NewRawKey and FetchRootKey from the WalletController interface
In this commit, we remove two methods from the WalletController
interface which were previously used by the funding reservation process
(NewRawKey) and the p2p network (FetchRootKey) in order to derive
various keys for operation. This methods are no longer necessary as the
KeyRing interface implements the functionality in a deterministic
manner.

lnwallet/btcwallet: during initial creation catch the case of an existing wallet
In this commit, due to the recent changes within lnd itself, it may be
possible that a wallet already exists when the wallet has been signaled
to be created. As a result, *always* open the wallet ourselves, but
allow an existing wallet to already be in place.

lnwallet/btcwallet/btcwallet: adds extra double spend case
Adds an extra case to the select statement to catch
an error produced by btcd. The error is meant to signal
that an output was previously spent, which can appear
under certain race conditions in spending/broadcasting.
This caused our final itest to fail because it would
not try to recraft the justice txn.

84551c616f lnwallet/lnrpc: Expose sync status to gRPC interface
This commit adds wallet_best_block_timestamp to the gRPC interface.
This is done in order to allow clients to calculate progress while
lnd syncs to the blockchain. wallet_best_block_timestamp is exposed
via the GetInfo() rpc call. Additionally, IsSynced() returns the
WalletBestBlockTimestamp as the second value in the tuple
that is returned, providing additional detail when querying about the
status of the sync. The BtcWallet interface has also been updated
accordingly.

This commit was created to support the issue to
[Add progress bar for chain sync] (lightninglabs/lightning-app#10) in
lightning-app

lnwallet: fully validate all channel constraints in validateCommitmentSanity
This commit introduces changes to the validateCommitmentSanity
function to fully validate all channel constraints.
validateCommitmentSanity now validates that the
MaxPendingAmount, ChanReserve, MinHTLC, & MaxAcceptedHTLCs
limits are all adhered to during the lifetime of a channel.

When applying a set of updates, the channel constraints are
validated from the point-of-view of either the local or the
remote node, to make sure the updates will be accepted.

lnwallet/channel: move common calculation of balance into computeView
This commit moves common logic used to calculate the state
of a commitment after applying a set of HTLC updates, into
the new method computeView. This method can be used when
calculating the available balance, validating the sanity
of a commitment after applying a set of updates, and also
when creating a new commitment, reducing the duplication
of this logic.

lnwallet/channel: let evaluateHTLCView take mutate boolean
This commit adds a new boolean parameter mutateState to
evalueteHTLCView, that let us call it without neccessarily
mutating the addHeight/removeHeight of the HTLCs, which is
useful when evaluating the commitment validity without
mutating the state.
