For Part 1 of Issue #275. Create isolated private struct in
networkHandler goroutine that will de-duplicate
announcements added to the batch. The struct contains maps
for each of channel announcements, channel updates, and
node announcements to keep track of unique announcements.
The struct has a Reset method to reset stored announcements, an
AddMsg(lnwire.Message) method to add a new message to the current
batch, and a Batch method to return the set of de-duplicated
announcements.
Also fix a few minor typos.
This commit does to things: moves the prior ShortChannelID struct into
a new short_channel_id.go file, and also implements the new ChannelID’s
currently used within he specification.
These new ID’s are 32-bytes in length and used during initial channel
funding as well as during normal channel updates. During initial
channel funding, the ID is to be a random 32-byte string, while once
normal channel operation has began, the ID is to be (txid XOR index),
where index is the index of the funding outpoint.
