lnwire: update onion error encoding/decoding to match BOLT-0004
This commit updates the encoding/decoding for the onion errors to
properly match BOLT-0004. This commit does to major things: we increase
the max message size to 256 bytes to account for recent modifications
to the ChannelUpdate message, and also fold in the error code into the
failure message encapsulation itself.

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.

b86409cdb3 htlcswitch: recreate hlcswitch from scratch
This commit gives the start for making the htlc manager and htlc switch
testable. The testability of htlc switch have been achieved by mocking
all external subsystems. The concrete list of updates:

1. create standalone package for htlc switch.
2. add "ChannelLink" interface, which represent the previous htlc link.
3. add "Peer" interface, which represent the remote node inside our
subsystem.
4. add htlc switch config to htlc switch susbystem, which stores the
handlers which are not elongs to any of the above interfaces.

With this commit we are able test htlc switch even without having
the concrete implementation of Peer, ChannelLink structures, they will
be added later.

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.

lnwire: remove the Validate method from the Message interface
This commit revues the Validate method from the Message interface as
the method is no longer used and is a relic from an older version of
the codebase.

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.
