This commit begins the process of moving towards a more principled means of state tracking. We eliminate the mutateState argument from processAddEntry and processRemoveEntry and move the responsibility of mutating said state to the call-sites. The current call-sites of these functions still have their *own* mutateState argument which will be eliminated during upcoming commits. However, following the principle of micro-commits I opted to break these changes up to make review simpler.
lnwallet
The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
