our forks.

lnwallet: update reservation workflow to be segwitty 
Only nested p2sh or pure witness outputs are used when selecting coins
for inputs to a funding transaction.

The funding transaction output now uses p2wsh rather than regular p2sh.

All tests have been updated accordingly.

f9a8dcbc9c lnwallet: add ListUnspentWitness to WalletController 
This method has been added in order to allow lnd to collect eligible
unspent witness programs outputs from the wallet controller for use as
inputs to the funding transaction.

Additionally, the change address functions now also specify whether the
generated change address should be payable to a witness program or not.

10d52611cd lnwallet: introduce WalletController interface as a "base wallet" 
The WalletController will serve as a layer of separation between “base”
Bitcoin wallet logic, and the higher level Lightning Network logic. As
a result LightningWallet will no behave as an overly wallet, relying on
the lower wallet for basic services such as new address, signing etc.

Within this higher level lies the awareness of channel types, chain
monitoring, HTLCs, and so on.

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).

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.
