lnwire: document start of single funder workflow
This commit adds some additional documentation in the form of comments
to the start of the revised single funder workflow.

A primary change lies in the introduction of the exchange of Channel
Derivation Points (CDP’s) for both sides. Using CDP’s we can derive
channel authentication proofs which are both unforgettable and binding.

lnwire: add SingleFundingSignComplete msg to workflow
This commit adds the SingleFundingSignComplete message to the single
funder transaction workflow. This marks the second to last message sent
in the workflow. The message transports Bob’s signature for the
commitment transaction, allowing Alice to broadcast the funding
transaction as she can now refund her inputs.

lnwire: add SingleFundingComplete to single funder
This commit adds the SingleFundingComplete message to the single funder
channel workflow. This is the 3rd message sent in the workflow,
traveling from Alice to Bob once Alice is able to construct the final
commitment transaction.

Doesn't need to use a list, only needs to show each party's most recent
state.

1981001a29 Started working on state machine
* Added description in lnwire/README.md for state machine
* Figured out mutex stuff...
* Started the State Machine (using dummy functions for net/db)
* Minor corrections in wire protocol (changed some names/types)
    - Renamed StagingID to HTLCKey of type HTLCKey (uint64)

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

266c121510 Changed type in Accept/Complete & lnwire refactor
* FundingSignAccept and FundingSingComplete had *[]btcec.Signature and
  instead it's now []*btcec.Signature to match other slice types.
* Refactored lnwire's when doing readElement/writeElement on slices

0d4c78e90d FundReq/FundResp update / Refactor tests
* Added field
* Renamed FundingAmount and ReserveAmount to specify in FundingRequest
  and FundingResponse that it is for RequesterFundingAmount or
  ResponderFundingAmount
* Added PaymentAmount field to FundingRequest
* Added MinDepth field to FundingRequest and FundingResponse
* Fixed .Serialize() to show inputs/etc. only if there are fields
  available (prevents trying to dereference nil value)
* Add a bunch of Validate() conditions
* MASSIVE REFACTOR of tests (removed tons of redundancy)

a93b6dcee4 Messages for funding flow.
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".

02a9b1e237 While making things match closely with Rusty's wire protocol, I noticed
he didn't allow for multiple HTLCs. Gotta explain the rationale for that
that... will merge the progress in the next commit tomorrow.

f51a5a6458 Holy shit pointer crap was annoying! Serialize/deserialize works now.
Running "go test -v" will show the serialization and deserialization.

Doing the rest of the wire stuff should be *much* faster since I figured
everything out...
