lnwire: correct incorrect type numbers for UpdateFee, Shutdown, and ClosingSigned
In this commit we correct an off by one error on the Shutdown and
ClosingSigned message types. Additionally, we fix an error related to
the numbering of the UpdateFee message. With this we, gain proper
compatibility with the other implementations when it comes to
commitment hygiene, and also the cooperative closure process.

multi: retain original copyright on files copied/modified from btcsuite
Early in the lifetime of the project here were a few files we either
copied entirely, or used as the basis for code within lnd. Before this
PR, this was not recognized by retaining the original copyright. With
this commit, we remedy that by explicitly noting the copyright in the
relevant files.

Fixes #423.

f29b4f60e4 lnwire: add BOLT#2 channel reestablish message
In this commit the reestablish message have been added, which serves as
channel state synchronization message. Before exchanging the messages
for particular channel peers have to send it to each other as the
first message in order to be sure that non of the updates have been
lost because of the previous disconnect.

98956bc2fe lnwire: add specification onion errors
In this commit onion routing error from BOLT#4 have been added, the
initial error construction have been splitted on two parts: The first
part which contains the actual data will reside inside the lnwire
package because it contains all necessary function to decode/encode
the data. The second part obfuscation and hmac checking will resides
inside the lighting-onion package because it requires the key
generation.

lnwire: modify ReadMessage to no longer return the total bytes read
This commit modifies ReadMessage to no longer return the total bytes
read as this value will now be calculated at a higher level. The
io.Reader that’s passed to ReadMessage is expected to contain the
_entire_ message rather than be a pointer into a stream that contains
the message itself.

lnwire: convert message parsing to use the new minimal type header
This commit abandons our old bitcoin inspired message header and
replaces it with the bare type-only message headers that’s currently
used within the draft specification. As a result the message header now
consists of only 2-bytes for the message type, then actual payload
itself. With this change, the daemon will now need to switch to a
purely message based wire protocol in order to be able to handle the
extra data that can be extended to arbitrary messages.

lnwire: on Message interface convert Command to MsgType
This commit modifies the Message interface to convert the Command
method to a MsgType method that uses a new set of message type for all
the defined messages. These new messages types nearly exactly match the
message types used within the current draft of the BOLT specifications.

54b3541707 lnwire: add specification 'AnnounceSignature' message
In this commit announcement signature message has been added which is
needed when peers want to announce their channel to the rest of the
network. This message acts as half proof carrier, nodes exchanges
their half proofs with each other and after that they are able to
construct the full proof.

LN) to a single payment preimage.

lnwire: morph CancelHTLC into UpdateFailHTLC, remove HTLCAddReject
This commit morphs the prior CancelHTLC into the new UpdateFailHTLC
message and also gets rid of the obsolete HLTCAddReject message while
we’re at it.

The primary change from the CancelHTLC message to the UpdateFailHTLC
message is that the CancelReason is now simply called Reason and that
it’s now an opaque encrypted set of bytes. With this update the failure
messages are now more flexible (they can even carry new
ChannelUpdate’s) and also don’t reveal the exact cause of failure to
intermediate nodes.

lnwire: morph CommitSignature into CommitSig
This commit renames and modifies the CommitSignature message to more
closely match the CommitSig message defined within the current set of
draft specifications.

The major change within the new message is that we now longer
explicitly specify the update log index of the remote node that this
signature covers. This is due to the fact the revocation message now
also double as acknowledgements of the remote parties recevied
commitment update messages.

the features which are supported by both sides.

lnwire+peer: introduce new error for unknown message type for forward compat
This commit adds a new error type to the `lnwire` package:
`UnknownMessage`. With this error we can catch the particular case of a
an error during reading that encounters a new or unknown message. When
we encounter this message in the peer’s readHandler, we can now
gracefully handle it by just skipping to the next message rather than
closing out the section entirely.

This puts us a bit closer to the spec, but not exactly as it has an
additional constraint that we can only ignore a new message if it has
an odd type. In a future release, we’ll modify this code to match the
spec as written.

lnwire+lnd: Make Logging Messages Great Again
This commit modifies the login of sent/recv’d wire messages in trace
mode in order utilize the more detailed, and automatically generated
logging statements using pure spew.Sdump.

In order to avoid the spammy messages due to spew printing the
btcec.S256() curve paramter within wire messages with public keys, we
introduce a new logging function to unset the curve paramter to it
isn’t printed in its entirety. To insure we don’t run into any panics
as a result of a nil pointer defense, we now copy the public keys
during the funding process so we don’t run into a panic due to
modifying a pointer to the same object.

327768f4ad routing: Move tools inside lnd. Refactor and delete unneeded stuff
Use [33]byte for graph vertex representation.
Delete unneeded stuff:
1. DeepEqual for graph comparison
2. EdgePath
3. 2-thread BFS
4. Table transfer messages and neighborhood radius
5. Beacons

Refactor:
1. Change ID to Vertex
2. Test use table driven approach
3. Add comments
4. Make graph internal representation private
5. Use wire.OutPoint as  EdgeId
6. Decouple routing messages from routing implementation
7. Delete Async methods
8. Delete unneeded channels and priority buffer from manager
9. Delete unneeded interfaces in internal graph realisation
10. Renamed ID to Vertex

This commit adds Ping and Pong messages to the suite of lnwire
messages. The usage of these messages within the daemon are similar to
the usage of Bitcoin’s ping/pong messages. Pings are to be sent
periodically with a random nonce to check connection activity and also
to gauge latency. Pong’s are to be sent in reply to ping messages,
echo’ing the same nonce used.

lnwire: remove the HTLC timeout msg in favor of a HTLC cancel msg
This commit removes the previous HTLC timeout in message in favor of a
HTLC cancel message. Within the protocol, a timeout message would never
be sent backwards along the route as in the case of an HTLC timeout
before/after the grace period, the course of action taken would be to
broadcast the current commitment transaction unilaterally on-chain.

f8c851769f multi: initial integration of routing module
This commit integrates BitFury's current routing functionality into lnd. The
primary ochestration point for the routing sub-system in the routingMgr. The
routingMgr manages all persistent and volatile state related to routing within
the network.

Newly opened channels, either when the initiator or responder are inserted into
the routing table once the channel is fully open. Once new links are inserted
the routingMgr can then perform path selection in order to locate an "optimal"
path to a target destination.
