lnwallet+routing: modify BlockChainIO.GetUtxo to be light client friendly
This commit modifies the GetUtxo method of the BlockChainIO interface
to be more light client friendly by introducing a height hint which
gives light clients that don’t have UTXO set commitments a way in which
they can restrict their search space. Light clients will now be able to
have a concrete cut off point in the chain as they scan backwards for
spentness of an output.

multi: update btcsuite API's to latest upstream changes
This commit makes a large number of minor changes concerning API usage
within the deamon to match the latest version on the upstream btcsuite
libraries.

The major changes are the switch from wire.ShaHash to chainhash.Hash,
and that wire.NewMsgTx() now takes a paramter indicating the version of
the transaction to be created.

lnwallet/btcwallet: fix bug in GetUtxo for BlockChainIO implementation
This commit fixes an unnoticed bug within btcwallet’s implementation of
the BlockChainIO interface, specifically the GetUtxo method. In order
to maintain compatibility with Bitcoin Core’s gettxout method, btcd
doesn’t return an error if the targeted output is actually spent.

We weren’t properly detecting this, but we do now by creating a new
error which is returned in the case of a nil error but a nil return
value.

lnwallet/btcwallet: fix bug in implementation of GetUxo
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.

lnwallet+lnrpc: convert GetCurrentHeight to GetBestBlock in BlockChainIO
This commit expands the data returned by the current GetCurrentHeight
to also return the current best block hash, expanding the method into
GetBestBlock. Additionally, the current best BlockHash is also now
displayed within the GetInfo RPC call.

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.
