9ffac9eae1 lnwire: update NodeAnnouncement to handle multiple addresses
This commit modifies address handling in the NodeAnnouncement struct,
switching from net.TCPAddr to []net.Addr. This enables more flexible
address handling with multiple types and multiple addresses for each
node. This commit addresses the first part of issue #131 .

lnwire: create distinct type for UpdateFailHTLC failure reason
This commit creates a distint type for the opaque failure reason within
the UpdateFailHTLC message. This new type is needed as this is the only
variable length byte slice within the protocol and therefore requires a
length prefix in order to serialize/deserialize properly.

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.

3dd619fb35 lnwire: Add BOLT#1 'init' message
'init' message is the first message reveals the features supported or required
by this node. Nodes wait for receipt of the other's features to simplify error
diagnosis where features are incompatible. This message will help negotioate the
the features which are supported by both sides.

lnwire: add cancellation reason to htlc cancel messages
This commit adds a new field to the CancelHTLC message which describes
the event that led to an HTLC being cancelled up stream.

A new enum has been added which describers the “why” concerning the
cancellation of the HTLC. Currently the encoding and back propagation
of the errors aren’t properly implemented as defined within the spec.
As a result the current error types provide to privacy as the error are
in plain-site rather doing being properly encrypted.

multi: update btcsuite API's to latest upstream changes
This commit makes a large number of minor changes concerning API usage
within the deamon to match the latest version on the upstream btcsuite
libraries.

The major changes are the switch from wire.ShaHash to chainhash.Hash,
and that wire.NewMsgTx() now takes a paramter indicating the version of
the transaction to be created.

lnwire: remove old routing/discovery messages
This commit removes the older routing/discovery messages from the
unwire package, as we’ll be converging towards BOLT07 in the near-term.
In the mid to far term we’ll be revisiting integrating Flare into the
newer scheme in order to take advantage of its scaling characteristics.

lnwire: modify Alias to only track the non-zero portion of wire msg
This commit modifies the Alias type to only hold the non-zero portion
of the alias as encoded on the wire. Previously the entire 32-bytes
would be read and stored, including the zeroes at the end used as
padding. Within the constructor, we now parse the alias properly,
discarding the trailing zeroes within the passed byte slice.
Additionally, the .String() method of Alias will now also only print
the non-zero prefix of the decoded alias.

a20594b0bf lnwire: switch to using a fixed 64-byte encoding for signatures (#86)
This commit modifies the encoding of signatures on the wire to use 
a fixed-size 64-byte format. This change is required as the current spec
draft dictates that all signatures be encoded as `R` and `S` as 32-byte
big-endian integers. With this, signatures are now always a _fixed_ size 
slice of bytes on the wire, which is nice to have. 

Fixes #83.

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

lnwire: all hashes within the protocol are now 32-bytes
We now enforce that the site of all revocation pre-images+hashes (used
for HTLC’s) are now 32-bytes.

Additionally, all payment pre-images are now required to be 32-bytes
not he wire. There also exists a Script level enforcement of the
payment pre-image size at a lower level.

This commit serves to unify the sizes of all hashes/pre-images across
the codebase.

lnwire: channels are now identified by outpoint
This commit modifies most of the wire messages to uniquely identify any
*active* channels by their funding output. This allows the wire
protocol to support funding transactions which open several channels in
parallel.

Any pending channels created by partial completion of the funding
workflow are to be identified by a uint64 initialized by both sides as
follows: the initiator of the connection starts from 0, while the
listening node starts from (1 << 63). These pending channel identifiers
are expected to be monotonically increasing with each new funding
workflow between two nodes. This identifier is volatile w.r.t to each
connection initiation.

  protocol. Both sides can update their Commitments unliaterally without
  waiting for the other party's signature. Will have basic/preliminary

This is the most different due to segwit (the rest of the messages are
simple).

I still need to simplify/refactor the tests, they're "messy".

Running "go test -v" will show the serialization and deserialization.
