This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
This commit refactors the remaining usage of WriteElements. By
replacing the interface types with concrete types for the params used in
the methods, most of the encoding of the messages now takes zero heap
allocations.
This commit changes the WriteElement and WriteElements methods to take a
write buffer instead of io.Writer. The corresponding Encode methods are
changed to use the write buffer.
Removes the MaxPayloadLength function from the Message interface
and checks that each message payload is not greater than MaxMsgBody.
Since all messages are now allowed to be 65535 bytes in size, the
MaxPayloadLength is no longer needed.

lnwire: update quickcheck tests, use constant for Error
multi: update unit tests to pass deep equal assertions with messages
In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.
In this commit, we export the ReadElements and WriteElements functions.
We do this as exporting these functions makes it possible for outside
packages to define serializations which use the BOLT 1.0 wire format.
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.
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.
