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.

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).

3fe82f475f lnwallet: correctly adjust cleared funds during AddHTLC 
* When adding an HTLC, the update to settled balances are to the side
sending the HTLC.

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.

1772108544 lnwallet: start of HTLC update logic 
* moved sorting of transaction outside of createCommitTx also us to add
HTLC’s before sorting
* On the fence about the proxy object design, will re-visit once we
start to implement the p2p code.

4fdb2763e6 channeldb: create new channeldb package, update lnwallet to use new API 
* Initial draft of brain dump of chandler. Nothing yet set in stone.
* Will most likely move the storage of all structs to a more “column”
oriented approach. Such that, small updates like incrementing the total
satoshi sent don’t result in the entire struct being serialized and
written.
* Some skeleton structs for other possible data we might want to store
are also included.
* Seem valuable to record as much data as possible for record keeping,
visualization, debugging, etc. Will need to set up a time+space+dirty
cache to ensure performance isn’t impacted too much.
