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.

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).

Subject: [PATCH] Fix Codec log spam
Mojang did NOT add dataconverters for world gen configurations
that they CHANGED. So, the codec fails to parse old data.
This fixes two instances:
- IntProvider is new and Mojang did not account for old data.
Thankfully, only ColumnPlace needed to be special cased.
- TreeConfiguration had changes. Thankfully, they were
only renames for one value and thankfully defaults could
be provided for two new values (WITHOUT changing behavior).

Subject: [PATCH] Optimise WorldServer#notify
Iterating over all of the navigators in the world is pretty expensive.
Instead, only iterate over navigators in the current region that are
eligible for repathing.
