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.

87603e780f channeldb: re-design OpenChannel schema, update tests
The state of OpenChannel on disk has now been partitioned into several
buckets+keys within the db. At the top level, a set of prefixed keys
stored common data updated frequently (with every channel update).
These fields are stored at the top level in order to facilities prefix
scans, and to avoid read/write amplification due to
serialization/deserialization with each read/write.

Within the active channel bucket, a nested bucket keyed on the node’s
ID stores the remainder of the channel.

Additionally OpenChannel now uses elkrem rather than shachain, delivery
scripts instead of addresses, stores the total net fees, and splits the
csv delay into the remote vs local node’s.

Several TODO’s have been left lingering, to be visited in the near
future.

631e76519e channeldb: switch to Open/Create methods rather than New
Commit includes basic tests for Open/Create. Additionally, rather than
relying on btcwallet’s addmgr for encryption/decryption, this package
now exposes a simple crypto system interface.

8ce8c29af6 chainntfns: add basic tests for confirmation+spending notifications
* The tests as written will be general to all future implementations of
ChainNotifier allowing future implementers to easily ensure their
implementation meets the expected behavior.

* The tests will be moved to the outer directory once a registration
mechanism for notifier implementations is in place.

e92fc5f495 chainntfs: switch BtcdNotifier to directly use btcrpcclient
* Turns out the NotificationServer on btcwallet doesn’t sever full
blocks, nor notify for arbitrary transactions. Instead, we now create a
new client specifically for BtcdNotifier.

* Final implementation is simpler, less dependent on newer btcwallet
features in flux. Additionally, this decouples the chain notifications
from the wallet. Enabling reliance on btcd for notifications, in
conjunction with an independent wallet that satisfies the to-be-drafted
Wallet interface.

unimplemented however.

b913bda472 chainntfs: expand ChainNotifier interface
* The `NotificationTrigger` struct has been dropped. Instead we know
simply employ a non-blocking send over a chan struct. This moves the
responsibility of triggering callbacks a level above to the registering
client.

* Confirmation notifications also now have a counter part in order to
notify a caller of the scenario wherein a funding transaction drops out
of the chain due to a re-org. A “neagtiveConf” value will be sent to
the client over a channel in this case. This will allow a caller to
re-register for another confirmation notification. Note that due to
this scenario, callers should also register for notifications
concerning spends of the counterparty’s inputs to the funding
transaction. If a second spend (other than the funding) is detected,
the channel should be closed immediately.

* Notifications concerning spends now also include the spending
transaction, hash, and the input on the spending transaction at which
the outpoint is spent.

d2d37ce1ab make it way faster
there were a lot of dumb things in Ingest() that made it really slow.
Like re-hashing the tx a bunch of times.  And re-saving it to the
db redundantly.

also added local bloom filters.  Maybe some concurrency issues if you
generate an address just as you're getting a tx with that address but
that doesn't seem like a real problem.  Cheap to rescan anyway.

So it's faster and works better.
