07b0d5ca3e lnwallet: once the reservation workflow is complete, wait then open the payment channel
* Hooks into the ChainNotifier infrastructure to receive a notification
once the funding transaction gets enough notifications.
* Still need to set up the notification grouting within a
LightningChannel to watch for uncooperative closures, and broadcasts
and revoked channel states.

6e0cfaf7ec lnwallet: re-introduce rpc calls during channel reservation workflow
* In preparation for regression testing once nodetest is finished.
* These sections we’re previously uncommented to allow for testing the
wallet without a full-node hooked up.

lnwallet before notes is finished.

986eb83ceb chainntfs: create new ChainNotifier for bfcd-based notifications
* Currently depends on the wallet, but that will change in the near
future due to new additions to btcwallet currently under review.
* Re-orgs aren’t intelligently handled yet. To be done along with tests
in a later commit.

8154b96d67 chainntfs: flesh out initial draft of interface
* So far very simple, only notifications for tx confirmations, and
outpoint spends.
* Our two cases are: waiting for the funding transaction to reach a
depth of N confirmations, and open channels being notified of the
counterpart trying to cheat them by broadcasting an invalidated
commitment tx.

27744a3582 lnwallet: add logic for adding/removing HTLCs
* Updates to the channel are made atomic, and consistent via a proxy
object: “ChannelUpdate” which encapsulates an update transaction. Only
one update transaction may be outstanding at any time.
* Update transactions are initiated via AddHTLC or SettleHTLC.
* Once a transaction has been begun, in order to complete the update
the transaction must first be presented with a signature from the
counter-party for our new version of the commitment tx
(VerifyNewCommitmentSigs), and finally to atomically commit the
transaction, the counterparty’s pre-image to their previous revocation
hash must be validate (Commit).

b2cb33c3c2 lnwallet: add documentation to ChannelReservation
* Workflow along with expected call orders have been documented.
* With this, the initial iteration of ChannelReservation is mostly
complete.
* However, there are still some unfinished steps internally within the
wallet related to processing. Such as factoring proper tx fees,
splitting fees, some node interaction etc.

f3849f5c10 Structs for Wire Protocol HTLCs and Commitments
* Structs and wire messages for HTLCs
* Wire protocol for a state machine with no blocking(!!!)
  (I will write the state machine)
  TL;DR: Can do multiple HTLC modifications in-flight, dead simple wire
  protocol. Both sides can update their Commitments unliaterally without
  waiting for the other party's signature. Will have basic/preliminary
  notes in the README
* Added **swp to .gitignore because of vim annoyances

* moved sorting of transaction outside of createCommitTx also us to add
HTLC’s before sorting

start to implement the p2p code.

a93b6dcee4 Messages for funding flow.
This is the most different due to segwit (the rest of the messages are
simple).

I still need to simplify/refactor the tests, they're "messy".
