This commit will allow the general public to build lnd without jumping
through hoops setting up their local git branches nicely with all of
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.

lnwallet: use InputScripts struct within ChannelReservation 
This allows the reservation workflow to support pure witness program
outputs, as well as witness programs nested within p2sh.

Olaoluwa Osuntokun 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.

Olaoluwa Osuntokun 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.

Simply to compile, channel.go will be replaced with lnstate soon
enough.

Olaoluwa Osuntokun fe6d71e95e lnwallet: accept channeldb as a param in constructor 
lnwallet is no longer responsible for creating/opening channeldb. The
call is now expected to do so.

Olaoluwa Osuntokun fa05ee9a22 lnwallet: move pubKey comparison for funding output spend into spendMultiSig func

the reservation workflow.

Olaoluwa Osuntokun 4632894562 lnwallet: move teardown of rpctest before setup to ensure proper cleanup 
* Previously, if the call to SetUp(..) returned an error, then the test
harness would fail to stop the running bcd process, and clean up the
test directories. This would cause any subsequent tests to fail. This
commit remedies this scenario.
 2016-02-05 12:32:23 -08:00
Olaoluwa Osuntokun 1a8ae48807 lnwallet: point rpctest at my in-progress fork+branch

Olaoluwa Osuntokun daeecd5fc0 lnwallet: nuke most of setup.go, no longer needed w/ wallet.Loader 2016-02-03 12:01:45 -08:00
Olaoluwa Osuntokun b3cdc6167f lnwallet: switch over to using btcwallet's new Loader type 
Allows us to remove a lot of duplicated code pertaining to wallet
setup. We also gain hooks into the wallet to trigger callbacks once the
wallet is created/opened.
 2016-02-03 12:01:45 -08:00
Olaoluwa Osuntokun 92c14c99c3 lnwallet: update tests to utilize the in-progress btcsuite/btcd/rpctest package 
Instead of creating “fake” utxos for bob, and alice. We now employ a
dedicated mining node to hand out utxos, and generate blocks with hand
picked transactions.

Olaoluwa Osuntokun 80ce49a883 lnwallet: update btcwallet and chain.Client to new upstream API's 
A major change for btcwallet adding a new RPC wallet, refactoring parts
of the wallet, and introducing new functionality has been introduced.
This commit updates lnwallet to the API changes. A future commit will
change lnwallet to use some of the new functionality such as the
notification server, etc.

Olaoluwa Osuntokun 034cbef66d lnwallet: avoid goroutines waiting for channel open indefinitely blocking 
Select over the quit channel in order to shutdown goroutines waiting
for funding txn confirmations. Without this we may leak goroutines
which are blocked forever if the process isn’t exiting when the walet
is signaled to shutdown.

Olaoluwa Osuntokun d96cf0ec64 lnwallet: fix receiver htlc script 
* Fixes a bug in script_utils.go. CSV instead of CLTV was being used
  within the timeout clause of the receivers HTLC (sender can reclaim
the HTLC).

Olaoluwa Osuntokun 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.
 2016-01-14 23:58:04 -08:00
Olaoluwa Osuntokun 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.
 2016-01-14 23:58:04 -08:00
Olaoluwa Osuntokun cf65aaa2c9 lnwallet: have wallet return db so it can be closed during shutdown

Olaoluwa Osuntokun f52b8370bc lnwallet: populate the update totem during channel initialization 2016-01-14 23:56:11 -08:00
Olaoluwa Osuntokun 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).

Olaoluwa Osuntokun 895d70e79f lnwallet: add funding tx p2sh output to lnchannel

transactions.
 2016-01-14 23:56:10 -08:00
Olaoluwa Osuntokun 3fe82f475f lnwallet: correctly adjust cleared funds during AddHTLC 
* When adding an HTLC, the update to settled balances are to the side
sending the HTLC.

Olaoluwa Osuntokun 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.

Olaoluwa Osuntokun 1772108544 lnwallet: start of HTLC update logic

start to implement the p2p code.

Olaoluwa Osuntokun 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.
