lnwallet: correct scaling for fee-per-byte to fee-per-weight, divide by 4
This commit corrects an error in the scaling as currently implemented
in the default static fee estimator. The spec draft has an error and
erroneously recommends multiplying by 4 to arrive at the fee-per-weight
from the fee-per-byte. This is incorrect as with the segwit block-size
increase, the ratio is 1/4 rather than 4.

lnwallet: use distinct fee rate for funding transaction coin selection
This commit modifies the coin selection logic around selecting inputs
for a funding transaction to query the fee estimator directly (and use
fee-per-byte), rather than use the fee estimate which was passed into
the context.

We also use the value passed into the InitChannelReservation method
directly rather than make a call to the fee estimator. With this
change, the responder to a funding workflow will now properly adopt the
fee-per-kw suggested by the funder of the channel.

lnwallet: simplify remote balance computation for single funder
The remote balance in the case of a single funder workflow is simply
what ever the pushSat amount is. The capacity - fundingAmt in this
scenario would always be zero, so we simply just set it directly to
pushSat.

channeldb: change MinFeePerKb to FeePerKw in OpenChannel struct
This commit modifies the name of a field in the OpenChannel struct to
better reflect its actual usage within this protocol. The FeePerKw
represents the amount of satoshi to be paid as fees per kilo-weight.
This field is set at the opening of a transaction and will be able to
be updated properly via the usage of the update_fee method.

4ac7cc719f lnwallet: replace hard-coded fees and adjust tests accordingly
This commit replaces the hard-coded 5000 satoshi fees with calls to the
FeeEstimator interface. This should provide a way to cleanly plug in
additional fee calculation algorithms in the future. This change
affected quite a few tests. When possible, the tests were changed to
assert amounts sent rather than balances so that fees wouldn't need to
be taken into account. There were several tests for which this wasn't
possible, so calls to the static fee calculator were made.

abe2e502d5 lnwallet: add FeeEstimator interface, StaticFeeEstimator implementation
This commit adds the FeeEstimator interface, which can be used for
future fee calculation implementations. Currently, there is only the
StaticFeeEstimator implementation, which returns the same fee rate for
any transaction.

320bed7e6b lnwallet: add CommitFee field to OpenChannel
In order to cleanly handle shutdowns and restarts during state machine operation, the fee for the current

7768415adc test: change integration tests to assert amounts sent rather than balances.
This commit changes the SingleHop and MultiHop integration tests to
assert amounts sent rather than balances. Because fees can be odd
amounts, this change makes it such that fee amounts don't need to be
explicitly taken into account in the tests.

routing: close exit chan before ntfnChan to cancel topology clients
This commit fixes a panic due to a send on a closed channel that could
possibly occur depending on the order of channel closes when a client
goes to cancel a topology notification client.

Previously we closed the ntfnChan first, this would possible result in
a panic as the goroutine may have succeeded on a send at the same time
the channel was closed. Instead, we now close the `exit` channel first
which is meant to be a signal to the goroutine that the client has been
canceled.

peer: fix panic bug in watiForChanToClose
This commit fixes a panic bug in the watiForChanToClose method caused
by a logic error leading to the return value of the function at times
being a nil pointer in the case that an error occurred. We now avoid
such an error by _always_ returning from the function if there’s an
error, but conditionally (in a diff if-clause) sending an error over
the error channel.

chainntnfs/btcdnotify: fix historical confirmation dispatch bugs
This commit fixes to distinct bugs in the way we previously dipatched
notifications for transactions which needed a historical dispatch.

Previously we would compare transactions when scanning the block using
the `tx.Hash` field. This was incorrect has the `Hash` field is
actually the wtxid, not the txid which should be the item being
compared. We fix this within the second bug fix by actually using the
txid to find the proper transaction.

The second fix has to due with a slight race condition which led to an
off-by-one error when dispatching the historical confirmation. If while
we were dispatching the confirmation, a new block was found, then we
could calculate the wrong block height (off by one) as we were using
the ‘currentHeight’ instead the height of the block which included the
transaction.

routing: reject channel announcement if connected vertexes are unknown
This commit modifies the processing in the routing package eo new
announcements. Previously,  if we cgot a cnew channel announcement but
didn’t yet know of the verses that the chanell connected, the
cnnounacment would be accepted. This behavior was eronoues as if the
channel were to be queried for, the DB query would fail as we would be
unable to retrieve the two nodes involved int he channel.

To avoid such an error case, we will now _reject_ any channel
announcements in which we don’t yet have a valid node announcement for
the connected nodes. This case has been inserted into the handling of
channel announcement, a new test has been added, and finally older
tests have also been updated to ensure that nodes are added to the
database _before_ the edge is.

rpc: non-existence of a nursery report is no longer an error
This commit fixes a slight logic error that could render the
`pendingchannels` RPC unusable if a node was on the reciting end of a
channel force close with no time-locked balance. In such a case the
channel wouldn’t be sent to the utxoNursery, resulting in an “contract
not found error”.

To fix this behavior, we’ve created a typed error that can be checked
within the RPC, thus we no longer treat this routine case as an error
case.

breacharbiter: don't watch for channel closes if time locked balance is non-zero
This commit fixes a slight logic error in the breachArbiter. Previously
we wouldn’t watch a pending channel for closure if the regular
(settled) balance was non-zero. However, this was incorrect, as it’s
possible for us to be on the receiving side of a channel force closure.
This error would leave certain channels as “pending close zombies”
forever until a user manually deleted the entry (or promoted it to be
fully closed).

To fix this, we now utilize the new `TimeLockedBalance` field to make a
better judgment as to if the utxoNursery is watching over a channel or
not.

This commit adds the total time locked balance of a closed channel at

close transactions, or if they should watch a channel for closure or
not.

lnwire: fix serialization order of features+addresses in NodeAnnouncement
This commit fixes a deviant in the way we serialize and deserialize the
node announcement message from that which is currently in the spec.
Before this commit we reversed the order of features and addresses.
Instead, on the wire, features should come _before_ the addresses.

We also add a new temporary feature bit to ensure nodes that don’t
directly connect to each other if they don’t have this new update.
However, this will also partition any current tests nets when new nodes
join them as the digest signed has changed, therefore invalidating any
older messages.

Fixes #207.

server: eliminate possible initial connection churn by ignoring duplicate inbound conns
This commit fixes a bug that was introduced when the connection
handling was re-worked to properly handle the case of concurrent
connections being made. In certain cases after a successful initial
connection, a peer’s stray goroutine would still attempt to establish a
second outbound connection even though a connection had already been
established. This was properly handled by the connecting peer, but not
he receiving peer. This commit adds the additional logic to the
receiving peer to ensure that we properly handle this case.

peer: ensure no messages are sent/processed _before_ all channels loaded
This commit fixes a bug which could at times cause channels to be
unusable upon connection. The bug would manifest like the following:
two peers would connect, one loads their channels faster than the
other, this would result in the winning peer attempting to extend their
revocation window. However, if the other peer hadn’t yet loaded the
channel, then this would appear to them to be an unknown channel.

We properly fix this issue by ensure all channels are loaded _before_
any of the goroutines needed for the operation of the peer are
launched.

routing: abandon ChainNotifier for FilteredChainView
This commit modifies the routing package to no longer use the
ChainNotifier for pruning the channel graph. Instead, we now use the
FilteredChainView interface to more (from the ChannelRouter’s PoV)
efficiently maintain the channel graph.

Rather than scanning the _entire_ block manually, we now rely on the
FilteredChainView to provide us with FilteredBlocks which include
_only_ the relevant transactions that we care about.

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.
