multi: move Input interface and related code
This commit is a step to split the lnwallet package. It puts the Input
interface and implementations in a separate package along with all their
dependencies from lnwallet.

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.

b98e993d76 lnallet: remove a TODO from signer.go
The TODO indicated that the fmt.Errorf call should be changed
to use the errors package, which allows for wrapping of errors
as necessary.

lnwallet/btcwallet: Use signDesc.HashType when signing
Tis commit makes the btcwallet signer implementation use
signDesc.HashType instead of SigHashAll when signing
transactions. This will allow the creator of the transaction
to specify the sighash policy when creating the accompanying
sign descriptior.

lnwallet/btcwallet: remove FundingSigner, implement MessageSigner
This commit removes the now deprecated FundingSigner struct as part of
the btcwallet package, and instead replaces it within an implementation
of the MessageSigner interface.

multi: minor coding style and comment clean ups post-discovery merge
This commit implements some minor coding style, commenting and naming
clean up after the recent major discovery service was merged into the
codebase.

Highlights of the naming changes:
* fundingManager.SendToDiscovery -> SendAnnouncement
* discovery.Discovery -> discovery.AuthenticatedGossiper

The rest of the changes consist primary of grammar fixes and proper
column wrapping.

a23715a9c7 lnwallet: add message signer
Added the signer which will be needed in the funding manager to sign
the lnwaire announcement message before sending them to discovery
package. Also in the future the message signer will be used to sign
the users data.

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: 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.
