discovery: make sure we do not block the read queue

[ziggie1984]

We increase the sync buffer for the syncer. Previously it was at
5 we increase it to 50. Moreover we make sure we process the
gossip messages in a async way.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

So I think that is the problem, in 19 we now throttle the outgoing message, this in combination with the decreased msg buffer size can easily end up with our node not reading the Ping/Pong responses in time and also delaying other messages, for example the Commitment Dance

So that is just a short term fix, we need to separate gossip from normal messages.

We might also think of starting the other method in the ProcessRemoteAnnouncement asynchronously like:

ApplyGossipFilter :

lnd/discovery/gossiper.go

Line 910 in 8e96bd0

if err := syncer.ApplyGossipFilter(ctx, m); err != nil {
