In this commit, we remove the per channel `sigPool` within the `lnwallet.LightningChannel` struct. With this change, we ensure that as the number of channels grows, the number of gouroutines idling in the sigPool stays constant. It's the case that currently on the daemon, most channels are likely inactive, with only a hand full actually consistently carrying out channel updates. As a result, this change should reduce the amount of idle CPU usage, as we have less active goroutines in select loops. In order to make this change, the `SigPool` itself has been publicly exported such that outside callers can make a `SigPool` and pass it into newly created channels. Since the sig pool now lives outside the channel, we were also able to do away with the Stop() method on the channel all together. Finally, the server is the sub-system that is currently responsible for managing the `SigPool` within lnd. |

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.
