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.

This commit modifies the readElement and writeElement functions to add

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.

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 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.

normal channel operation has began, the ID is to be (txid XOR index),
where index is the index of the funding outpoint.

e549a3f0ed fundingmanager: move final funding steps from wallet to funding manager.
Once a channel funding process has advanced to the point of broadcasting
the funding transaction, the state of the channel should be persisted
so that the nodes can disconnect or go down without having to wait for the
funding transaction to be confirmed on the blockchain.

Previously, the finalization of the funding process was handled by a
combination of the funding manager, the peer and the wallet, but if
the remote peer is no longer online or no longer connected, this flow
will no longer work. This commit moves all funding steps following
the transaction broadcast into the funding manager, which is available
as long as the daemon is running.

funding: disallow channel creation before lnd is synced to the chain
This commit adds a new restriction around funding channels at the
daemon level: lnd nodes will not allow either the initiation or the
acceptance of a channel before the node is fully synced to the best
known chain.

This fixes a class of bug that arises when a new node joins the network
and either attempts to open a channel or has a channel extended to them
before the node is fully synced to the network.

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: add new 'PushSatoshis' field to SingleFundingRequest
This commit adds a new paramter to the initial channel creation:
‘PushSatoshis’. This new field allows the funder of a channel to push
over a certain amount to the responder as part of the initial channel
state. This ability creates a new streamlined UX of finalizing a
payment as a part of the channel creation.

lnwire: add IncorrectValue as HTLC error type, fix typos
This commit adds a new HTLC error type: IncorrectValue. This error type
is to be used when an HTLC that’s extended to the final destination
does not match the expectation of the destination.

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: modify fundingOpen to include channel ID rather than SPV proof
This commit modifies the SingleFundingOpen message to include the
compact channel ID of the finalized transaction rather than a “fake”
SPV proof. This change is a stop-gap which allows us to implement
portions of BOLT07 without yet fully implementing all parts of BOLT[02,
03].

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: remove channel graph announcement validation tests
This commit removes the previous test cases which excised the proper
validation of graph announcements on the network. As full generation of
the authenticated messages has not yet been implemented, these tests
aren’t currently applicable.

In a future commit, these tests will be replicated on the new discovery
package which will handle producing the channel proofs and also fully
validating them.

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.

lnwire: temporarily disable chan/node announcement validation
This commit temporarily disables the signature validation for all
announcement related messages which should be authenticated by one or
many parties. This feature is being disabled as we don’t yet generate
valid signatures for our advertisements and the validation of the
messages should be placed in the layer 3 discovery service rather than
within within the message parsing layer.

lnwire: separate ChannelID into a distinct struct, add tests
This commit separates out the ChannelID into a new file, with
additional helper methods for conversion and formatting. With this
commit, the struct is now more general purpose and can be used in the
new routing package, database, and other related sub-systems.
