routing: add sufficient link capacity to our relaxation condition
This commit modifies our modified version of Dijkstra's to include
sufficient link capacity within the algorithm’s relaxation condition.
With this change, we’ll now avoid exploring the graph in the direction
of a link that has insufficient capacity, allowing us to terminate path
finding more quickly.

routing: introduce a heap to keep track of closest nodes during pathfinding
This commit introduces a new heap struct that will be used to keep
track of the next closest node to the source during path finding within
our modified Dijkstra's algorithm.

peer: fix bug in handshake wherein RevokeAndAck would be sent first
This commit fixes a bug in the opening handshake between to peers. The
bug would arise when on or many channels were active between a node
establishing a new connection. The htlcManager goroutines will
immediately attempt to extend the revocation window once they’re
active. However, at this time, the init message may not yet have been
sent as the two executions are in distinct goroutines.

We fix this bug by manually writing the init message directly to the
socket, rather than traveling through the queueHandler goroutine. With
this, we ensure that the init message is _always_ sent first.

35813ad939 server: fix panic when error occures on peer intialization (#163)
If an error occurs during, peer initialization then 'p' is nil. This 
may cause a panic while accessing the peer's member 
variables.

To avoid such panics, we now omit the call to `p.Disconnect` 
and also directly access the `connmgr.ConReq` variable if it's 
non-nil.

test: don't panic within lightningNetworkWatcher if lnd is shutting down
This commit fixes an issue in the newly added integration tests level
topology notifications that caused tests to erronosely panic when the
daemon was detected to be shutting down. This issue was notified by
AndrewSamokhvalov.

We fix this issue by checking if the error is a shutdown error, and
exiting early if so. Additionally we add a fail-fast case if the quit
channel for the node has already been closed.

cmd/lncli: append a new-line when using encoding/json to print resp
It was noticed by 21E14 on Github that when we fall back to using
golang’s encoding/json lib in special cases when printing the proto
responses in JSON form, the value printed lacked a new-line at the end.
This would cause the output to flow into bash prompts.

This issue has been fixed by simply appending a newline character to
the end of the formatted JSON output.

Fixes #160.

brontide: replace aead/chacha20 with x/crypto/chacha20poly1305
This commit replaces aead’s chacha20 library with the official golang
implementation. We should see a bit of a performance increase on amd64
as the assembly for the library uses the SIMD AVX2 instructions in the
inner loop. In the future assembly will be written for other platforms,
so we’ll see a performance increase across the board.

Fixes #146.

multi: replace usage of fastsha256 with crypto/sha256
This commit removes all instances of the fastsha256 library and
replaces it with the sha256 library in the standard library. This
change should see a number of performance improvements as the standard
library has highly optimized assembly instructions with use vectorized
instructions as the platform supports.

test: remove many sleeps from integration test by using new topology ntfns
This commit removes a number of sleeps from the set of current
integration tests by replacing them with a synchronous (w/ a timeout)
block until one or many channels are detected as being open within the
network.

As a result, the tests are now more robust, many flakes have been
eliminated, and finally this shaves a few second off of the integration
testing runs.

routing: fix bug when sending topology ntfns to multiple clients
This commit fixes a bug which was originally introduced when the
topology notifications were added to the channel router. The issue was
that a pointer to the loop-scope range variable was being passed into
the goroutine which dispatches the notification rather than the value
itself. It seems that the memory location is re-used between range
iterations causing the same client to receive _all_ the notifications.

This bug is fixed by passing a copy of the client struct rather than a
pointer to the range variable.

In the process, we also add some additional debug logging messages, and
remove the Curve parameter from any public keys involved in a
notification so the pretty print properly.

test: modify new network announcement hook to be in node level
This commit modifies the two newly added network announcement hook stop
be at the lightningNode level rather than on the level of the entire
test framework. With this, callers are now able to better utilize the
newly added RPC’s since they can target particular peers and wait for
network messages to be processed rather then depending on a single node
(Alice) for information about the announcements propagated within the
network.

test: add ability to register for LN channel notification to framework
This commit adds the ability for test authors using the integration
testing framework to hook into real-time notifications for
network-level announcements concerning channel openings, closings, and
updates. With this commit we should be able to eliminate a number of
the sleeps within the test framework with synchronous calls (time outs)
to the new methods added in this PR.

rpc: implement new streaming SubscribeChannelGraph RPC call
This commit implements the new server-side streaming RPC call within
the current default implementation of the RPC server. With this, the
new functionality can now be used within the integration tests to
achieve a greater degree of synchronization in the tests. As a result,
we should be able to eliminate many of the sleeps lingering within the
tests.

routing: include the channel point of chan within edge update ntfn
This commit modifies the `ChannelEdgeUpdate` struct to include the
channel point itself within the notifications. Such a change improves
the notificaiton experience for callers as it allows them to filter out
update notifications based on a familiar object within the codebase: a
channel point.

ce1fcc0bd6 utxonursery: handle non-existant to-self outputs
If a forceClose happens and the to-self output is below the dust value,
then that output will be non-existant in the commitment transaction.
UtxoNursery now handles that case by checking to see if the accompanying
selfOutPutSignDescriptor is nil. If it is nil, then it will ignore it.

a6a503bf28 lnwallet: ForceCloseSummary should check if to-local output exists
If the value of the to-local output is below the dust limit, the
ForceCloseSummary should not include a sign descriptor for this output.

We also find the proper to-self output by looking for the expected public
key script and not assume that no HTLC outputs exist.

52b56b8cf2 lnwallet+test: no dust outputs in commitment transaction + tests
Currently non-HTLC outputs will be accepted in the commitment
transaction as long as it is non-zero. We change this by not allowing
outputs with a value lower than the dust limit. The value of such
an output will go towards transaction fees.
