Improve syncer startup #532
Description
What
Currently we check every 30s if we are synced, this was a hacky way of doing it which was never meant to stick. Instead we should have a way of telling the syncer if we are behind.
Why
Qubic recently caused a lot of re orgs, most of these blocks were passed around by syncing not through block notifications, needing to wait an extra 30s to sync blocks is a lot of wasted time for anyone who uses cuprated to mine.
Where
Syncer, p2p.
How
A channel to wake the syncer if we are behind?
