Subject: [PATCH] Consolidate flush calls for entity tracker packets
Most server packets seem to be sent from here, so try to avoid
expensive flush calls from them.
This change was motivated due to local testing:
- My server spawn has 130 cows in it (for testing a prev. patch)
- Try to let 200 players join spawn
Without this change, I could only get 20 players on before they
all started timing out due to the load put on the Netty I/O threads.
With this change I could get all 200 on at 0ms ping.
(one of the primary issues is that my CPU is kinda trash, and having
4 extra threads at 100% is just too much for it).
So in general this patch should reduce Netty I/O thread load.

Subject: [PATCH] Optimise nearby player lookups
Use a distance map to map out close players.
Note that it's important that we cache the distance map value per chunk
since the penalty of a map lookup could outweigh the benefits of
searching less players (as it basically did in the outside range patch).

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Optimise non-flush packet sending
Places like entity tracking make heavy use of packet sending,
and internally netty will use some very expensive thread wakeup
calls when scheduling.
Thanks to various hacks in ProtocolLib as well as other
plugins, we cannot simply use a queue of packets to group
send on execute. We have to call execute for each packet.
Tux's suggestion here is exactly what was needed - tag
the Runnable indicating it should not make a wakeup call.
Big thanks to Tux for making this possible as I had given
up on this optimisation before he came along.
Locally this patch drops the entity tracker tick by a full 1.5x.
