htlcswitch: if unable to add half in channel link, properly increment bandwidth
This commit fixes an existing bug, wherein if we failed to account for
the fact that if we we’re unable to add an HTLC for any reason other
than an overflown commitment transaction, then we wouldn’t properly
re-add the available bandwidth of the offending HTLC.

htlcswitch: in local outgoing payment attempt print a nicer error if no bandwidth
This commit modifies the error we return to the end user in the case of
an insufficient link capacity error when handling a local payment
dispatch. Previously we would return a
lnwire.CodeTemporaryChannelFailure, however, this isn’t necessary as
this is a local payment attempt and we don’t give up any sensitive
information by returning the best available bandwidth, and what we need
to complete the payment.

routing: modify TestSendPaymentRouteFailureFallback to use non-critical error
In this commit we modify the existing
TestSendPaymentRouteFailureFallback to use a non-critical error aside
from FailChannelDisabled. This is necessary as the behavior of the
current error handling can fail due to us sending in a nil error.

routing: add preliminary version of more intelligent payment error handling
This commit modifies the way we currently interpret errors when sending
payments via the SendToSwitch method. We split the errors into two
broad sections: critical errors which cause us to abandon the payment
dispatch all together, and errors which are transient meaning we should
continue trying to remainder of the returned routes.

Note that we haven’t yet properly implemented all the necessary
measures such as filtering edges that are detected as being temporarily
inactive, etc.

This change should correct erroneous behavior such as continuing to try
all available routes in the face of an invalid payment hash error and
the like.

routing: move path caching into FindRoutes
This commit modifies the way we do path caching. Rather than only
caching within SendPayment, we now cache routes within FindRoutes. This
is more natural as SendPayment eventually calls FindRoute. As a result
of this commit, queries to FindRoute are now properly cached, speeding
up applications which are focused on graph visualization or querying
rather than sending payments.

peer: within loadActiveChannels, skip channel if FundingLocked not processed
This commit fixes a bug to wrap up the recently merged PR to properly
handle duplicate FundingLocked retransmissions and also ensure that we
reliably re-send the FundingLocked message if we’re unable to the first
time around.

In this commit, we skip processing a channel that does not yet have a
set remote revocation as otherwise, if we attempt to trigger a state
update, then we’ll be attempting to manipulate a nil commitment point.
Therefore, we’ll rely on the fundingManager to properly send the
channel all relevant subsystems.

fundingManager: conditional select on arbiterChan and peer.newChannels
This commit adds a select statement for sending on the fundingManager's
arbiterChan and the peer's newChannels channel. This makes sure we won't
be blocked sending on these channels in case of a shutdown.

tests: cleanup of fundingmanager_test.go
This commit cleans the fundingManager tests by extracting
most of the common code from the different test cases into
assert methods, making the test cases easier to follow
and distinguish.

It also adds a new test for the case where the peer goes
offline, and the fundingManager must wait for it to come
online before it can send the fundingLocked message and
continue the funding flow.

fundingManager: use NotifyWhenOnline when sending fundingLocked.
The fundingManager will register with the server to get notified
when the targetted peer comes online, in case of a failed send
of the fundingLocked message. This is necessary because if the
peer is not connected yet (or was disconnected while we were
waiting for the funding tx to confirm), we cannot continue the
the opening process before the peer successfully has received
the fundingLocked.

htlcswith/link: resend fundingLocked from channelLink when numUpdates == 0.
In the case where the channelLink get started and the number of
updates on this channel is zero, this means no paymenys has been
done using this channel. This might mean that the fundingLocked
never was sent successfully, so we resend to make sure this
channel gets opened correctly.

fundingManager: handle duplicate fundingLocked
This commit adds a channel barrier on fundingManager startup for
channels where the opening process is not finished. This fixes
a bug where we after restarting the fundingManager would receive
the fundingLocked message, and crash when trying to close the
non-existing barrier.

In case we received a fundingLocked message after our own opening
process was finished, we would crash with the same error. We
therefore check if the channel barrier exists before we try to
close it.

It also adds functionality to fundingManager that makes it
ignore a fundingLocked message it receives for a channel where
this is already received. This is necessary when we in case of
a reconnection resend the fundingLocked since we cannot be sure
the remote has received it.

The fundingmanager tests are also updated to check that the
fundingLocked messages are sent and handled correcly, and also
exercise the scanarios described above.

funding channels. Additionally, we add some additional text 
to the insufficient funding error to detail that we don't have 
enough witness outputs.

lnwallet: expand TestForceClose to ensure outgoing HTLC's can be swept
This commit expands the existing TestForceClose test case to add an
HTLC (outgoing) to Alice’s commitment transaction before force closing.
We then ensure that both the pre-signed timeout transaction _and_ the
sign descriptor to sweep the second-level output are fully valid.

lnwallet: fix bug in extractHtlcResolutions, ensure slice is contiguous
This commit fixes an existing bug within extractHtlcResolutions. The
prior code would use an index to assign the returned
OutgoingHtlcResolutions into a single slice. However, this is invalid
as there are two cases where an HTLC might be skipped: if it’s an
incoming HTLC, or if the HLTC itself is dust from the PoV of the
commitment chain.

To fix this, we now instead use append to add items to the slice. This
ensure that we don’t have any “empty” items in between fully populated
items.
