safer check for the queues if we're blocked on a send, should work even if we're blocked on a link packet send

when we detect we're blocked, only drop packets often enough to make sure the existing queue's size is non-increasing, and always drop the worst packet from a random flow with odds based on the total size of packets queued for that flow

use a dedicated per-stream writer goroutine, send messages to it over a 1-buffered channel, this eliminates most of the false positive blocking that causes drops
