multi: update build to latest version of neutrino+btcwallet
In this commit, we update the build to point to the latest version of
neutrino and btcwallet. The latest version of neutrino includes a number
of bug fixes, and new features like reliably transaction broadcast. The
latest version of btcwallet contains a number of bug fixes related to
properly remove invalid transactions from its database.

routing/chainview: demote logging of new utxos for filter to Trace
It was previously Debug, which would spam the logs at startup, and not
provide very useful (human-readable) information.

multi: update to latest BitcoindClient interface
In this commit, we introduce a nice optimization with regards to lnd's
interaction with a bitcoind backend. Within lnd, we currently have three
different subsystems responsible for watching the chain: chainntnfs,
lnwallet, and routing/chainview. Each of these subsystems has an active
RPC and ZMQ connection to the underlying bitcoind node. This would incur
a toll on the underlying bitcoind node and would cause us to miss ZMQ
events, which are crucial to lnd. We remedy this issue by sharing the
same connection to a bitcoind node between the different clients within
lnd.

routing/chainview: give neutrino backend more time to catch up for re-org test
In this commit, we modify the test to explitlcy give the neutrino
backend more time to catch up compared to the RPC backends. We do this
as a recent change has been made in the neutrino backend to wait for the
filter headers to finish syncing before proceeding with the rescan
itself. As a result, we'll need to account for this in the test and
sleep enough to give the backend a chance to catch up.

routing/chainview: modify the UpdateFilter method to take a channeldb.EdgePoint
In this commit, we update the existing UpdateFilter method to take the
new channeldb.EdgePoint struct in place of the prior wire.OutPoint. We
must do this as the caller now typically has this type due to the
preparation to enable lnd to be able to be compatible with the new
neutrino protocol.

routing/chainview/bitcoind: improve filterMtx locking
In this commit, we modify the granularity of the locking
around the filterMtx in the bitcoind chainview, such that
we only lock once per block connected or filter update.
Currently, we acquire and release the lock for every
update to the map.

We also fix a bug that would cause us to not fully remove
all previous outpoints spent by a txn when doing manual
filter, as we previously would only remove the first output
detected.

routing/chainview/neutrino: cache filter entries
This commit alters the neutrino chainview such that it
caches the filter entries corresponding to watched
outpoints at the moment they are added to the filter.
Previously, we would rederive each filter entry when
reconstructing the relevant filter entries, which
would lead to unnecessary work on the gc. Now, each is
created at most once, and reused across subsequent
reconstructions.

routing/chainview: use blockEventQueue for neutrino block events
This commit makes use of the blockEventQueue within the neutrino
implementation of FilteredChainView to ensure connected and
disconnected blocks are consumed in order by the reader.

It also specifies that neutrino is not to send disconnected blocks
notifications during rescans, making it consistent with the btcd
implementation.

routing/chainview: implement staleBlocks for btcd view.
This commit moves btcd view away from using the deprecated
callbacks onBlockConnected/Disconnected, and instead use
onFilteredBlockConnected/disconnected.

This commit also implements the sending of disconnected blocks
over the staleBlocks channel. To send these blocks, the
blockEventQueue is used to ensure the ordering of blocks are
correctly kept.

It also changes the way filter updates are handled. Since we
now load the tx filter to the rpc server itself, we can call
RescanBlocks instead of manually filtering blocks. These
rescanned blocks are also added to the blockEventQueue,
ensuring the ordering is kept.

routing/chainView: add blockEventQueue data structure
blockEventQueue is an ordered queue for block events sent from a
FilteredChainView. The two types of possible block events are
connected/new blocks, and disconencted/stale blocks. The
blockEventQueue keeps the order of these events intact, while
still being non-blocking. This is important in order for the
chainView's call to onFilteredBlockConnected/Disconnected to not
get blocked, and for the consumer of the block events to always
get the events in the correct order.

8fa2b95c12 lnd: remove seelog logger
The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.

There are two primary advantages to the new logger implementation.

First, all log messages are created before the call returns.  Compared
to seelog, this prevents data races when mutable variables are logged.

Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging").  Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.

Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output.  The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files.  Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.

routing/chainview: make filter updates synchronous for neutrino
This commit fixes a possible race condition wherein a call to
FilterBlock after a call to UpdateFilter would result in the call to
FilterBlock not yet using the updated filter. We fix this by ensuring
the internal chain filter is updated by the time the call to
FilterBlock returns.

routing/chainview: optimize neutrino implementation of FilterBlock
This commit optimizes the neutrino implementation of FilterBlock method
of the ChainView interface. The old implementation would _always_ fetch
the entire block and manually scan through it. Instead, we can just
fetch the filter, and then if the items match, fetch the block itself.
This will save bandwidth during a lnd node’s pruning of the channel
graph after a period of dormancy.

chainntnfs/neutrinonotify: add ChainNotifier implementation for neutrino
This commit adds an initial rough implementation father ChainNotifier
interface for neutrino, our new light client implementation. This
implementation largely borrows from the existing BtcdNotifier
implementation. As a result, a follow up commit will perform two
refactoring in order to further consolidate code.
