This commit does two things. First we fix a deadlock bug within boltdb
that could arise when the channel router attempted to open a
transaction, while the retransmission loop was attempting to send a
message to the channel router (circular wait). Second, we’ve refactored
out the retransmission into its own function. This allows us to kick
off retransmission as soon as the AuthenticatedGossiper is created.
This commit modifies the recently modified logic for self-channel
retransmission to exclude pruning *our* channels which haven’t been
updated since the broadcastInterval. Instead, we only re-broadcast
channels of ours that haven’t been updated in 24 hours.
This commit fixes an existing bug in the announcement processing of the
authenticated gossiper. We will now only examine an incoming
announcement for validity if it targets the chain that we’re currently
active on.
