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.

c233b8816e htlcswitch: increase payment timeout in bydirectional unit test
During travis tests the latency of payment might lead to test failure,
for that reason we increase the waiting timeout.

routing: wait for topology clients to fully exit before closing ntfn chan
This commit fixes a send on closed channel panic by adding additional
synchronization when cancelling the notifications for a particular
topology client. We now ensure that all goroutines belonging to a
particular topology client exit fully before we close the notification
channel in order to avoid a panic.

lnwallet: fix race condition when forwarding by creating new pubkey
This commit fixes a race condition that would at times occur in the
htlcswitch.TestChannelLinkBidirectionalOneHopPayments test case. A race
condition would occur in the goroutine running ReceiveNewCommitment
compared with the grouting that would obtain the snapshot in order to
make a forwarding decision.

We fix this by creating a new public key for each new commitment
transaction such that we complete avoid the read/write race condition.

config: don't log to stderr if lnd.conf isn't found
This commit fixes a bit of a wart in the configuration file handling
wherein if the config file isn’t found, an error was printed to stderr.
At times, this would cause the testing framework to erroneously mark as
test as failed. Instead, we now keep a particular config file error,
and check that, printing to a warning log level.

htlcswitch: add a new UpdateFeePolicy to ChannelLink interface
This commit adds a new method to the ChannelLink interface which is
meant to allow outside sub-system to update the forwarding policy of a
channel. This can be triggered either by a new RPC method, or
automatically by some sort of control system which seeks to optimize
fee revenue, or block off channels, etc.

htlcswitch: implement full HTLC onion payload validation logic
This commit puts a missing piece in place by properly parsing and
validating the per hop payload received in incoming HTLC’s. When
forwarding HTLC’s we ensure that the payload recovered is consistent
with our current forwarding policy. Additionally, when we’re the “exit
node” for a payment, then we ensure that the HTLC extended matches up
with our expectation w.r.t the payment amount to be received.

htlcswitch: modify the HopIterator interface to utilize per-hop payloads
This commit modifies the HopIterator interface to allow nodes that
receive incoming HTLC’s to make forwarding decisions based on the
returned peer hop information, rather than just the next hop. With this
change, we can now enforce our routing policy, and reject any HTLC’s
that violate the policy.

funding: we process the funding locked message _after_ shortChanID is known
This commit adds a new bit of synchronization to the funding manager to
ensure that we only process the funding locked message directly _after_
the short channel ID has become available within the channel. This
fixes a possible bug wherein we would receive the funding locked
message, and register the channel with the switch without yet knowing
the short chan ID. This would then cause any HTLC’s routed to the new
channel to fail, as it would be using the incorrect short channel ID.

funding: obtain and populate shortChanID for MarkChannelAsOpen
This commit modifies the funding process to use the short channel ID,
rather than only the opening block height to mark a channel as open
once it has been confirmed. With this change, the short channel ID
information will now be available immediately after the channel has
been confirmed in the chain.

routing: add ToHopPayloads method to routing.Route
This commit adds a new method to the routing.Route struct:
ToHopPayloads. This function will converts a complete route into the
series of per-hop payloads that is to be encoded within each HTLC using
an opaque Sphinx packet.

We can now use this function when creating the sphinx packet to
properly encoded the hop payload for each hop in the route.

This commit modifies the OpenChannel struct to include the full short
