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.

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.

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.

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.

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).

624e776987 add shell spv testing mode
To try uspv, do ./lnd -spv
The remote node is hardcoded in shell.go.  If you aren't
running a full node on localhost, specify where to connect to.
Nearby nodes will be much faster but random testnet nodes on the
internet should also work.

2f9fc87636 fix sync, remove sum from TxStore
Synchronization now seems to work well even with the rapid fire
many inv-block messages that I'm seeing often on testnet3.  I'm
not 100% sure measuring the len() of a buffered channel is safe
but it seems to work fine.
Got rid of 'sum' in the TxStore; can be computed from GetAllUtxos()
Might want to merge SCon and TxStore since there's not much going
on in TxStore any more...

f231113b90 some cleanup, store spent txs
pretty much everything is db based now.  Still some concurrency issues
when multiple block inv messages come in (which they do) where
we used len(mBlockQueue) as a check for being synched up, which doesn't
quite work.  Find a better way to do that...

cf01e02d64 fix dumb loop break error
break was outside the if bytes.Equal {}, oops.  only checked first output.
Works now.  Concurrency also seems OK but need to test more.

3b774ef361 move tx ingest to all db, fixes sync
Sync was non-deterministic because ingest was concurrent.
Now receiving tx messages is blocking, but that's OK, they really need
to be in the right order because the whole point of bitcoin is to put
txs in the right order.  SendTx still has a problem that the change address
may not be recognized by ingest.

83dff432b1 mutex helps, still some sequence errors from mblocks
Seems that merkle blocks can return txs out of sequence, unlike
regular blocks which have to be in temporal/sequential order.
so maybe want to absorb ALL txs from mblock, then expel all?

5c2bbff3eb fix more sync problems. Seems to work OK
One edge case is with long chains of unconfirmed txs.
All self-signed txs are stored, but not used to negate false incoming utxos yet.

6ef9dc3d4a not saying it works, but it works better
redo how db and header sync works, somewhat simpler but a little
recursve-ish.  There is still an off by 1 error somewhere with headers.

d9afd623eb new stxo struct and more db methods
I'm getting away from having both in-ram and on-disk stores for the transaction store data.
it should all be on disk, it's safer that way.  It might be slower but this will not
process many txs / second anyway.

5a7c04bdb5 incoming invs and tx signing
when we get inv messages, txs are easy but blocks are a little tricky
block heigh synchronization is done via os' file system
signing is a bit inelegant (searches through inputs for pkscript matches)
but fast enough in practice

29d0c0cc6f fix bolt slices. db read / write works.
also switch heights from uint32 to int32, which I guess is what they use.
Makes this thing last 2 billion blocks shorter.  If we get past uint32 time.

709b8a05cd oh right, another fun thing I forgot about
When there's only the coinbase tx, the merkle root = the coinbase txid.
