lnwallet: don't sign new commitment if next revocation point is unknown
In this commit, we extend the initial check within SignNextCommitment
to bail out early if we don’t yet know the commitment point of the
remote party. This prevents a class of nil pointer panics if we attempt
to create a new state without yet having received the FundingLocked
message.

720a8c7e96 htlcswitch: Only send UpdateFee message when channel is eligible
This commit adds a check to `updateChannelFee` which skipssending the
`update_fee` message when the channel is not eligable for forwarding
messages (likely due to the channel's `RemoteNextRevocation` not yet
being set).

This addresses #470.

docs: update sample-lnd.conf
This commit adds additional documentation to the sample-lnd.conf, and
also ensures that users are able to drop it in without any issues. The
prior version left the namespace off several of the arguments, rendering
it unusable.

Fixes #462.

chainntnfs/neutrinonotify: fix early historical confirmation dispatch
In this commit, we fix an existing bug within the logic of the neutrino
notifier. Rather than properly dispatching only once a transaction had
reached the expected number of confirmations, the historical dispatch
logic would trigger as soon as the transaction reached a single
confirmation.

This was due to the fact that we were using the scanHeight variable
which would be set to zero to calculate the number of confirmations.
The value would end up being the current height, which is generally
always greater than the number of expected confirmations. To remedy
this, we’ll now properly use the block height the transaction was
originally confirmed in to know when to dispatch.

This also applies a fix that was discovered in
93981a85c0b47622a3a5e7089b8bca9b80b834c5.

chainntnfs: expand historical dispatch test case to detect early dispatches
In this commit, we extend the existing historical dispatch test case to
detect any instances of early dispatches. This catches a class of bug
within a ChainNotifier when the notifier will *always* dispatch early
no matter the number of confirmations. Currently, this test fails for
the neutrino notifier.

htlcswitch: ensure we don't dispatch local HTLC's to link that aren't eligible to forward
This commit fixes an existing bug wherein we would incorrectly attempt
to forward and HTLC to a link that wasn’t yet eligible for forwarding.
This would occur when we’ve added a link to the switch, but haven’t yet
received a FundingLocked message for the channel. As a result, the
channel won’t have the next revocation point available. A logic error
prior to this commit would skip tallying the largest bandwidth rather
than skipping examining the link all together.

Fixes #464.

peer: check LocalUnrevokedCommitPoint for nil-ness as it's optional
In this commit, we modify the logWireMessage function to ensure that we
don't attempt to nil out the LocalUnrevokedCommitPoint.Curve field
unless it's actually set. We need to do this as the field as actually
optional, and we may be reading a message from a node that doesn't
support the option.

Fixes #461.

routing: ensure we set the TotalFees value on routes properly
Before this commit, we wouldn’t properly set the TotalFees attribute.
As a result, our sorting algorithm at the end to select candidate
routes would simply maintain the time-lock order rather than also sort
by total fees. This commit fixes this issue and also allows the test
added in the prior commit to pass.

peer: when processing a msg, skip he funding barrier if it's a ChanSync message
This commit is a follow up to the prior commit: as it’s possible for
the channel_reestablish message to be sent *before* the channel has
been fully confirmed, we’ll now ensure that we process it to the link
even if the channel isn’t yet open.

peer: always load active channels upon connection reestablishment with peer
In this commit, we modify the logic within loadActiveChannels to
*always* load a channel, even if it isn’t yet fully confirmed. With
this change, we ensure that we’ll always send a channel_reestablish
message upon reconnection.

peer: properly process retransmitted FundingLocked message we've never processed
In this commit, we modify the logic within the channelManager to be
able to process any retransmitted FundingLocked messages. Before this
commit, we would simply ignore any new channels sent to us, iff, we
already had an active channel with the same channel point. With the
recent change to the loadActiveChannels method in the peer, this is now
incorrect.

When a peer retransmits the FundingLocked message, it goes through to
the fundingManager. The fundingMgr will then (if we haven’t already
processed it), send the channel to the breach arbiter and also to the
peer’s channelManager. In order to handle this case properly, if we
already have the channel, we’ll check if our current channel *doesn’t*
already have the RemoteNextRevocation field set. If it doesn’t, then
this means that we haven’t yet processed the FundingLcoked message, so
we’ll process it for the first time.

This new logic will properly:
  * ensure that the breachArbiter still has the most up to date channel
  * allow us to update the state of the link has been added to the
switch at this point
      * this link will now be eligible for forwarding after this
sequence

peer: unconditionally add a channel to the switch if it's open
In this commit we revert a prior change which was added after
FundingLocked retransmission was implemented. This prior change didn’t
factor in the fact that the FundingLocked message will *only* be
re-sent after both sides receive the ChannelReestablishment message.
With the prior code, as we never added the channel to the link, we’d
never re-send the ChannelReestablishment, meaning the other side would
never send the FundingLocked message.

By unconditionally adding the channel to the switch, we ensure that
we’ll always properly retransmit the FundingLocked message.

rpc: a link is now only active if it is eligible to forward HTLCs
In this commit, we further constrain the candidacy for an “active”
channel. In addition to being present within the link, it *must* also
have the RemoteNextRevocation set. Otherwise, this indicates that we
haven’t yet processed a FundingLocked message for this channel.

htlcswitch: ensure links are eligible to forward when selecting outgoing links
In this commit, when selecting a candidate link to forward a payment,
we’ll ensure that it’s actually able to take on the HTLC. Otherwise,
we’ll skip over the link itself. Currently, a link is only fully
eligible for forwarding, *after* we’ve received and fully processed the
FundingLocked message.

but in an intermediate state which indicates that it isn’t yet ready to

routing: ensure that new blocks connected monotonically increase in height
This commit fixes an existing bug within the ChannelRouter. Prior to
this commit, if the chain view skipped blocks or for some reason we had
a gap in blocks delivered, then we would simply accept them. This had
the potential to cause us to miss on-chain channel closure events. To
remedy this, we won’t process any blocks whose heights aren’t
*strictly* increasing.

A longer term fix would be to have the ChainView take a block height,
and re-dispatch any notifications from that height to the current
height.

config+test: increase default num confs for funding flows to 3
In this commit, we increase the default number of confirmations we
require for funding flows from 1 to 3. The value of 1 was rather
unstable on testnet due to the frequent multi-block re-orgs.
Additionally, a value of 3 ensures our funding transaction is
sufficiently buried before we deem is usable.
