lnwallet/btcwallet: remove unnecessary tx in mempool/chain checks
The checks to determine whether the transaction broadcast failed due to
it already existing in the mempool/chain are no longer needed since the
underlying btcwallet PublishTransaction call will not return an error
when running into these cases.

lnwallet: add LastUnusedAddress to WalletController interface
In this commit, we add a new `LastUnusedAddress` method to the
`WalletController` interface. Callers can use this new method to graph
the last unused address, which can be useful for UIs that want to
refresh the address, but not cause nearly unbounded address generation.

The implementation for `btcwallet` uses the existing `CurrentAddress`
method. We've also added a new integration tests to exercise the new
functionality.

3c1e0f2aef lnwallet/btcwallet: return best header timestamp while wallet is rescanning.
One way applications built on top of lnd can estimate sync percentage is
through comparing the current time to the best known timestamp of the
lnd wallet's sync state. Therefore, we should always return this
information even if the the wallet is not synced.

lnwallet/btcwallet: add lightning addr scope before wallet start
In this commit, we add the lightning address scope before the wallet
starts to prevent a race condition between the wallet syncing and adding
the scope itself. This became more apparent with the recent btcwallet
fixes, as several database transactions now occur between the wallet
being started and it syncing.

lnwallet/btcwallet: check output is under our control in FetchInputInfo
In this commit, we add an additional check to btcwallet's FetchInputInfo
method to ensure the output is actually under control of the wallet.
Previously, the wallet would assume the output was under its control if
the txid of the output was found within the wallet. This is not a safe
assumption to make however, because if we happened to be the sender of
this transaction, it would be found within the wallet but it's not
actually under our control. To fix this, we explicitly check that there
exists an address in our wallet for this output.

Add a maxconfirms argument to ListUnspentWitness
This change was inspired by #1984 - the underlying call to
ListUnspent supports a (min, max) range so it makes sense that
the WalletController interface can also support this; a
default no-maximum can be expressed using a MaxInt32 value.

lnwallet: fix ListTransactionDetails to ensure unconfirmed transactions are installed
In this commit, we fix a bug in the arguments to GetTransactions for the
btcwallet implementation of the WalletController interface. Before this
commit, we wouldn't properly return unconfirmed transactions. The issue
was that we didn't specify the special mempool height of "-1", as the
ending height. The mempool height is actually internally converted to
the highest possible height that can fit into a int32.

In this commit, we set the start to zero, and end to -1 (actually
2^32-1) to properly scan for unconfirmed transactions.

Fixes #1422.

lnwallet: use btcutil.NewAmount for BTC -> SAT conversions
In this commit, we fix an existing rounding related bug in the codebase.
The RPC interface for btcd and bitcoind return values in BTC rather than
in satoshis. So in several places, we're forced to convert ourselves
manually. The existing logic attempted to do this, but didn't properly
account for rounding. As a result, our values can be off due to not
rounding incorrectly.

The fix for this is easy: simply properly use btcutil.NewAmount
everywhere which does rounding properly.

Fixes #939.

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.

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.

lnwallet/btcwallet/blockchain: properly handle nil spend report
This commit adds an additional check in GetUtxo that
tests for the nil-ness of the spend report returned by
the neutrino backend. Previously, a nil error and
spend report could be returned if the rescan did not
find the output at or above the start height. This
was observed to have cause a nil pointer dereference
when the returning line attempted to access the output.
This case is now handled by returning a distinct error
signaling that the output was not found.

calculation within lnd which can then be extended to the internal
wallets.

lnwallet/btcwallet: fix bug in non-recognition of self-funds in chan force close
This commit fixes a bug which would cause the node on the _receiving_
side of a channel force close to be blind of their immediately funds
on-chain. The root of the issue was that within the btcwallet
implementation of the WalletController method ‘NewRawKey’, the wallet
wouldn’t request notifications for the new address, as the direct
function from the waddrmgr was used which skips registration of the new
address.

To fix, this, we now ensure that btcwallet will receive notifications
for keys used within the raw p2wkh commitment output. This ensures that
the wallet is aware of funds that are made available as a result of a
channel force closure by the channel counter party.

This commit fixes an unnoticed bug within btcwallet’s implementation of

to maintain compatibility with Bitcoin Core’s gettxout method, btcd

error which is returned in the case of a nil error but a nil return

This commit fixes a bug within the btcwallet implementation of the
BlockChainIO interface. The exact nature of the bug was a rounding
error that would only manifest if the value of the UTXO was below 1
BTC.

The tests within this package currently test channels with mostly whole
values of BTC, as a result the bug went unnoticed until now.

The fix itself is trivial: convert to an int64 AFTER performing the
multiplication to convert to satoshis from Bitcoin.

if it thinks it has fully synced to the tip of the current main chain.
This function can be useful within U.I’s to block off certain
functionality until the wallet is fully synced to the main chain.

lnwallet: extend the SignDescriptor to include a PrivateTweak
This commit extends the SignDescriptor with a single attribute, the
‘PrivateTweak’. The duties of the Signer interface have also been
augmented to properly derive a private key using the specified tweak,
iff it’s non-nil.

As currently defined in order to generate the proper private key based
off of a PrivateTweak, the signer is to add the tweak value to the
private key for the specified public key. This generated value is to be
used for signing within the specified context.

This change paves the way for automatic revoked output sweeping with
signatures generated directly by the Signer interface, maintaining the
structure of the abstraction.

A test has been added at the interface level in order to excerise each
WalletController’s implementation of the key derivation as currently
defined.

e515710a7d multi: use witnessScript everywhere instead of redeemScript
This commit consists of a mass variable renaming to call the pkScript being executed for segwit outputs the `witnessScript` instead of `redeemScript`. The latter naming convention is generally considered to be reserved for the context of BIP 16 execution. With segwit to be deployed soon, we should be using the correct terminology uniformly through the codebase. 

In addition some minor typos throughout the codebase has been fixed.

lnwallet/btcwallet: concretely implement the new TransactionSubscription interface
This commit returns the BtcWallet wrapper struct back to conformance to
the WalletController interface by adding support for
SubscribeTransactions.

The implementation of the lnwallet.TransactionSubscription consists
simply of a proxy goroutine which forwards notifications from the
wallet’s internal NotificaitonServer.

lnwallet/btcwallet: implement ListTransactionDetails
This commit implements the new ListTransactionDetails method within
btcwallet’s concrete implementation of the WalletController interface.
Both mined and unmined transactions are currently returned via the same
method. Unmined transactions are indicated by their lack of an
inclusion block hash and lack of confirmations.

lnwallet: modify btcwallet's SignOutputRaw method to get proper pubkey
This commit slightly modifies btcwallet’s SignOutputRaw method to work
properly in the case that the pkScript of the output being spent isn’t
one of the template pkScripts (p2pkh, multi-sig, etc). Rather than
examining the address, we now attempt to find the private key which
matches the public key passed within the sign descriptor.

lnwallet: add a BtcWallet implementation of WalletController
This commit adds the first concrete implementation of the
WalletController interface: BtcWallet. This implementation is simply a
series of wrapper functions are the base btcwallet struct.

Additionally, for ease of use both the BlockChain IO and Signer
interface are also implemented by BtcWallet. Finally a new WalletDriver
implementation has been implemented, and will be register by the init()
method within this new package.
