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: update single funder workflow to use revocation keys
This commit updates the messages sent during a single funder workflow
to utilize revocation keys rather than revocation hashes. This now
matches the latest updates to the commitment transaction.

The changes to the workflow are as follows:
  * the response message now carries the responder’s revocation key
  * the complete message now carries the initiator’s revocation key

Once the initiator receives the response message, it can construct both
versions of the commitment transaction as it now knows the responder’s
commitment key. The initiator then sends their initial revocation key
over to the responder allowing it to construct the commitment
transactions and give the initiator a sig for their version.

lnwire: channels are now identified by outpoint
This commit modifies most of the wire messages to uniquely identify any
*active* channels by their funding output. This allows the wire
protocol to support funding transactions which open several channels in
parallel.

Any pending channels created by partial completion of the funding
workflow are to be identified by a uint64 initialized by both sides as
follows: the initiator of the connection starts from 0, while the
listening node starts from (1 << 63). These pending channel identifiers
are expected to be monotonically increasing with each new funding
workflow between two nodes. This identifier is volatile w.r.t to each
connection initiation.

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.
