lnwire: eliminate the ErrorCode field within the Error message
This commit does away with the ErrorCode field in order to ensure that
we’re properly compatible with BOLT-0002. In the future the error code
field may be re-introduced as it’s much easier to check against an
internet error rather than interpret a byte slice describing the error.

lnwire: shift fields in NodeAnnouncment to match recent BOLT-0007 changes
This commit modifies the NodeAnnouncement message to ensure that it
matches the current spec ordering. The spec was recently modified to
place the feature vector first to allow for future changes to the
fields to be forwards compatible.

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.

lnwire: introduce new lnwire.MilliSatoshi type
This commit adds a new type to the lnwire package: MilliSatoshi. A
milli-satoshi is simply 1/1000th of a satoshi, and will be used for all
internal accounting when sending payments, calculating fees, updating
commitment state, etc. Two helper methods are added: ToBTC(), and
ToSatoshis() to make manipulation of the values easy.

lnwire: add a HtlcSigs field to the CommitSig message
This commit adds a new field to the CommitSig message: HtlcSigs. This
new field will house signatures for each of the HTLC’s on the newly
created commitment state. This addition allows us to implement the new
commitment transaction structure outlined within the specification
which modifies HTLC’s such that the claiming process is now a two-phase
process. The first state transitions an HTLC to the delay+claim state,
and the second state (after the delay has passed) allows the
broadcaster of the commitment transaction to sweep the HTLC’s.

Fixes #61.

lnwire: add new single funder messages from specification
This commit adds the new set of single funder messages from the
specification. As a result, after this commit and a follow up, all of
our messages will directly line up with those that are detailed within
the specification.

The new set of funding messages are very similar to our prior ones,
aside from the main difference of the addition of several channel level
constraints that give nodes control over their exposure, throughput,
and other values.

lnwire: modify RevokeAndAck to remove NextRevocationHash
This commit modifies the RevokeAndAck message in order to bring it more
in line with the current draft of the specification. The prior version
was based on a version that used a revocation hash for HTLC’s and a
revocation key for commitment outputs. The current commitment design
uses revocation keys uniformly throughout.

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: fix serialization order of features+addresses in NodeAnnouncement
This commit fixes a deviant in the way we serialize and deserialize the
node announcement message from that which is currently in the spec.
Before this commit we reversed the order of features and addresses.
Instead, on the wire, features should come _before_ the addresses.

We also add a new temporary feature bit to ensure nodes that don’t
directly connect to each other if they don’t have this new update.
However, this will also partition any current tests nets when new nodes
join them as the digest signed has changed, therefore invalidating any
older messages.

Fixes #207.

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

lnwire: replace all wire msg tests with a single property-based test
This commit does away with all the old manual message equality tests
and replace it with a single property-based test that uses the
testing/quick package. This test uses a single scenario which MUST hold
for all the messages type and all possible messages generated for those
types. As a result we are able to do away with all the prior manually
generated test data as the fuzzer to scan the input space looking for a
message that violates the scenario.

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: use ReadFull instead of Read when parsing feature vectors
This commit fixes a bug lingering in the decoding of the feature
vectors which was masked by the prior method of reading the _entire_
message from the stream before parsing it. The issue was that
performing a zero-byte Read on an io.Reader that’s purely streaming
will result in an indefinite block. We fix this bug by properly using
io.ReadFull in this context.
