d8e62f6898 back to one adr[] slice
all adrs can be converted on the fly and displayed both ways.
in the actual UI this shouldn't happen though.

Also utxos are sorted and signed properly.  utxo selection
is still pretty low tech.

fbd17846d4 split adrs up into two slices?
here is code to keep track of two sets of addresses -- the
regular ones and the witness ones.  But maybe those should be
merged becuase it's easy for other wallets to switch between them
and send to the same 20 byte pubkey hash but wintessified.
So maybe I'll change this stuff...

a175e098fa remove waitgroups from ingest block
It doesn't work; can ingest out of order within a block,
so if a block has gain then loss, you might read it as loss
then gains, missing the loss.
Also, tryna implement p2wpkh

e2dd892a4f add waitgroups to ingestBlock
seems to go a little faster but not much.
making ingest tx take a slice of txs would be faster probably.
but it seems network i/o is the limiting factor so maybe it's OK

4535b965cd implement hard mode
seems to work OK.  Could be sped up by local filters instead of
ingesting every tx from the block but I can do that later if
performance (mostly disk i/o) is an issue

once multiple connections are implemented, hard mode should forward
txs to blend in.

8518be13f7 add hard mode test methods
really simple to check block merkle root
next can modify "ingestMerkleBlock" to ingest either type of block.

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.

9eccb0638a I think this fixes all sync problems
add a bool to the HashAndHeight struct;
can indicate "final".  When the block market final comes in,
we don't enter wait state, but instead ask for headers.
when you don't get any headers, you wont need any blocks, and that
will assert the wait state.

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.

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

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.
