routing/chainView test: add testFilterBlockDisconnected
This commit adds a test for the FilteredChainView interfaces,
making sure they notify about disconnected/connected blocks
in the correct order during a reorg.

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.

chainntnfs+routing/chainview: reduce neutrino.WaitForMoreCFHeaders value
This commit reduces the neutrino.WaitForMoreCFHeaders parameter when
instantiating a neutrino instance as a lower value will allow the tests
to complete more quickly.

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.

routing/chainview: add behavioral interface level tests
This commit adds a new set of behavioral interface level tests to the
chain view package. This set of tests can now be used in order to check
proper conformity to this “specification” for all future
implementations of the chain view package.

chainview.FilteredChainView interface. The implementation of this
interface, BtcdFilteredChainView is backed by a web sockets connection
to an active btcd instance.

routing/chainview: add new chainview package for watching subsets of the UTXO set
This commit creates a new package as sub-package within the routing
package: chainview. This package is centered around a single interface
definition: the FilteredChainView. This interface is to be used to
allow the routing package to watch a _subset_ of the UTXO set for any
modifications. In the case of LN, the subset of the UTXO set that we
care about is the set of currently opened channels.

In a future commit the routing package will be modified to remove the
current full block scanning with processing of FilteredBlock
notification, and proper updates to the filter as observed by the
FilteredChainView.
