7535371238 htlcswitch: implement strict forwarding for locally dispatched payments
In this commit, we address an issue that could arise when using the
SendToRoute RPC. In this RPC, we specify the exact hops that a payment
should take. However, within the switch, we would set a constraint for
the first hop to be any hop as long as the first peer was at the end of
it. This would cause discrepancies when attempting to use the RPC as the
payment would actually go through another hop with the same peer. We fix
this by explicitly specifying the channel ID of the first hop.

Fixes #1500.
Fixes #1515.

htlcswitch/mock: drop messages if link is not online
In this commit, we modify the readHandler w/in
the mock peer to drop messages if it is unable
to find the target link. This has led to observed
race conditions related to removing a link and still
attempting to deliver messages. By removing this,
the readHandler shouldn't fail the test as a result.

htlcswitch/test_utils: bump fwdpkg gc timeout to 15s
This commit increases the fwdpkg garbage collection
interval to 15s, to mitigate the likelihood of it
interfering with our unit tests related to fwdpkgs.

htlcswitch/link: remove circuit deletion forgiveness
This commit removes the concept of "circuit deletion
forgivness" from the link. This was originally
implemented due to the strict semantics of the original
DeleteCircuit implementation, which would fail if we tried
to delete unknown circuits. Forgivness is used on startup
to ignore this error in case the circuits had already been
deleted before shutting down.

Now that the circuit deletion has been relaxed, this
behavior is no longer necessary, as requests to delete
unknown (or previously deleted) circuits will be ignored.

This is necessary for future changes regarding switch
cleanup, which may attempt to cleanup already deleted
circuits.

htlcswitch/circuit_map: relax circuit deletion
Previously, we would only allow deletion of circuits if all circuit keys
were found in the pending map.

In this commit, we relax this to allow for deletion of any circuits
that are found pending, and ignore those that are not found. This
is a preliminary step to cleaning up duplicate forwards that get caught
by the switch. It also allows us to gracefully handle any nodes that
are still afflicted by the split mailbox issue.

htlcswitch/circuit_map: prevent spewing secp curve in trace
Replaces the log statement in CommitCircuits so that
it prints the circuit key of the incoming channel. This way
we avoid spewing the secp curve stored in the ErrorEncrypter.

server: add goroutine watchChannelStatus
This commit adds a goroutine watchChannelStatus to the server, which
will query the switch for the status of all open channels every
InactiveChanTimeout / 4. If a channel's status has remained unchanged
during the last InactiveChanTimeout it'll send out a ChannelUpdate
setting the disabled bit accordingly.

lnd_test: use dave to listen for ChannelUpdates in testSendUpdateDisableChannel
This commit changes the test testSendUpdateDisableChannel to use Dave to
listen for channel updates, as was originally intended.

Since a ChannelUpdate won't propagate in the network if the channel is
already closed (if the closing transaction has been mined), we change
the closing procedure to initiate the closing process, wait for the
ChannelUpdates, then finally mining the closing transaction. This avoids
a propagation race between the mined block and the ChannelUpdate.

call will fail with "Outdated" and the announcement won't propagate.

autopilot: check if already connected before returning error
This commit fixes a small bug that could cause us to disconnect an
already connected peer if no addresses where provided to the ConnectPeer
method. Now we instead first check if we are already connected, and
return early.

In this commit, we add a new method to the network harness that allows
us to send funds to another party without confirming the transaction.
This will be useful for testing funding channels with outputs that have
not been confirmed yet.

autopilot/agent_test: pass in agent's quit chan to heuristic
In this commit, we alter our mock heuristic to also take in a quit chan.
It's possible that at the end of a test the agent is blocked on a
NeedMoreChans/Select call as their mock implementations use channels. To
prevent this, we use the agent's quit chan so that the heuristic can
safely exit once the agent does.
