Subject: [PATCH] Fix Non Full Status Chunk NBT Memory Leak
Any full status chunk that was requested for any status less than full
would hold onto their entire nbt tree and every variable in that function.
This was due to use of a lambda that persists on the Chunk object
until that chunk reaches FULL status.
With introduction of no tick, we greatly increased the number of non
full chunks so this was really starting to hurt.
We further improve it by making a copy of the nbt tag with only the memory
it needs, so that we dont have to hold a copy to the entire compound.

Adds a new method to fetch the location of a player's bed without generating any sync loads.
getPotentialBedLocation - Gets the last known location of a player's bed. This does not preform any check if the bed is still valid and does not load any chunks.

Subject: [PATCH] Protect Bedrock and End Portal/Frames from being destroyed
This fixes exploits that let players destroy bedrock by Pistons, explosions
and Mushrooom/Tree generation.
These blocks are designed to not be broken except by creative players/commands.
So protect them from a multitude of methods of destroying them.
A config is provided if you rather let players use these exploits, and let
them destroy the worlds End Portals and get on top of the nether easy.

Subject: [PATCH] Wait for Async Tasks during shutdown
Server.reload() had this logic to give time for tasks to shutdown,
however shutdown did not...
Adds a 5 second grace period for any async tasks to finish and warns
if any are still running after that delay just as reload does.

Subject: [PATCH] Workaround for Client Lag Spikes (MC-162253)
When crossing certain chunk boundaries, the client needlessly
calculates light maps for chunk neighbours. In some specific map
configurations, these calculations cause a 500ms+ freeze on the Client.
This patch basically serves as a workaround by sending light maps
to the client, so that it doesn't attempt to calculate them.
This mitigates the frametime impact to a minimum (but it's still there).
