Olaoluwa Osuntokun e942e70651 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.		2016-11-18 17:12:58 -08:00
