lnwire: replace instances of *btcec.PublicKey with [33]byte in ann messages
In this commit, we replace all instances of *btcec.PublicKey within the
announcement messages with a simple [33]byte. We do this as usually we
don’t need to immediately validate an announcement, therefore we can
avoid the scalar multiplications during decoding.

lnwire: add new ChanUpdateFlag for the ChannelUpdate flag bitmask
In this commit, we add a new type to the lnwire package:
ChanUpdateFlag. This type represent the bitfield that’s used within the
ChannelUpdate message to give additional details as how the message
should be interpreted.

lnwire: add observance of optional data loss fields to ChannelReestablish
In this commit, we add support within lnwire for the optional dataloss
fields in ChannelReestablish. With these fields, it’s possible to:
verify that the remote node really knows of the state of our prior
local commitment, and also that they’ve sent us the current commitment
point for their current state.

In the event of dataloss, it’s possible for the party which lost data
to claim their commitment output in the remote party’s commitment if
they broadcast their current commitment transaction.

a14a15641b lnwire: add new HtlcPoint to OpenChannel and AcceptChannel
In this commit, we begin implementing the latest spec change to reduce
the attack surface on online channels. In this commit, we introduce a
distinct HTLC base point which will be used to sign the second-level
HTLC transactions for each active HLTC on the commitment transaction of
the remote node. With this, we allow the commitment key to remain
offline, as it isn’t needed in routine channel updates, unless we need
to go to chain.

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.

lnwire: add new FundingFlag type for OpenChannel
In this commit we add a new type to the lnwire package: FundingFlag.
This type will serve as an enum to describe the possible flags that can
be used within the ChannelFlags field in the OpenChannel struct.

We also define the first assigned flag: FFAnnounceChannel, which
indicates if the initiator of the funding flow wishes to announce the
channel to the greater network.

lnwire: properly encode/decode addrs in NodeAnnouncement msg
This commit fixes an existing deviation in the way we encode+decode the
addresses within the NodeAnnouncement message with that of the
specification. Prior to this commit, we would encode the _number_ of
addresses, rather than the number of bytes it takes to encode all the
addresses.

In this commit, we fix this mistake by properly writing out the total
number of bytes, modifying our parsing to take account of this new
encoding.

42a263b29f wire: Correct fuzz test for MsgCommitSig.
This corrects the fuzz test in TestLightningWireProtocol for
MsgCommitSig to avoid creating an empty slice since the decoded message
only creates a slice when there are greater than zero signatures and an
empty slice is not considered equal to a nil slice under reflection.

This can be tested by running the TestLightningWireProtocol 1000 times
in a loop with and without this change.

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.

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: 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+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.

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: 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.

f3849f5c10 Structs for Wire Protocol HTLCs and Commitments
* Structs and wire messages for HTLCs
* Wire protocol for a state machine with no blocking(!!!)
  (I will write the state machine)
  TL;DR: Can do multiple HTLC modifications in-flight, dead simple wire
  protocol. Both sides can update their Commitments unliaterally without
  waiting for the other party's signature. Will have basic/preliminary
  notes in the README
* Added **swp to .gitignore because of vim annoyances
