Subject: [PATCH] Delay Chunk Unloads based on Player Movement
When players are moving in the world, doing things such as building or exploring,
they will commonly go back and forth in a small area. This causes a ton of chunk load
and unload activity on the edge chunks of their view distance.
A simple back and forth movement in 6 blocks could spam a chunk to thrash a
loading and unload cycle over and over again.
This is very wasteful. This system introduces a delay of inactivity on a chunk
before it actually unloads, which will be handled by the ticket expiry process.
This allows servers with smaller worlds who do less long distance exploring to stop
wasting cpu cycles on saving/unloading/reloading chunks repeatedly.

Subject: [PATCH] Fix missing chunks due to integer overflow
This patch fixes a bug in the WorldChunkManagerTheEnd class where the distance
from 0,0 squared overflows the maximum size of an integer. The overflow leads
to hard chunk borders around 370,000 blocks from 0,0. After this cutoff there
is a few hundred thousand block gap before end land resuming to generate at
530,000 blocks from spawn. This is due to the integer flipping back and forth.
The fix for the issue is quite simple, casting chunk coordinates to longs
allows the distance calculation to avoid overflow and work as intended.

Subject: [PATCH] Fix piston physics inconsistency - MC-188840
Pistons invoke physics when they move blocks. The physics can cause
tnt blocks to ignite. However, pistons (when storing the blocks they "moved")
don't actually go back to the world state sometimes to check if something
like that happened. As a result they end up moving the tnt like it was
never ignited. This resulted in the ability to create machines
that can duplicate tnt, called "world eaters".
This patch makes the piston logic retrieve the block state from the world
prevent this from occuring.
This patch also sets the moved pos to air immediately after creating
the moving piston TE. This prevents the block from being updated from
other physics calls by the piston.
Tested against the following tnt duper design:
https://www.youtube.com/watch?v=mS7xxNGhjxs
This patch also affects every type of machine that utilises
this mechanic. For example, dead coral is removed by a physics
update when being moved while it is attached to slimeblocks.
Standard piston machines that don't destroy or modify the
blocks they move by physics updates should be entirely
unaffected.
This patch fixes https://bugs.mojang.com/browse/MC-188840
This patch also fixes rail duping and carpet duping.

Subject: [PATCH] Maps shouldn't load chunks
Previously maps would load all chunks in a certain radius depending on
their scale when trying to update their content. This would result in
main thread chunk loads when they weren't really necessary, especially
on low view distances or "slow" async chunk loads after teleports or
other prioritisation.
This changes it to only try to render already loaded chunks based on
the assumption that the chunks around the player will get loaded
eventually anyways and that maps will get checked for update every
five ticks that movement occur in anyways.

Subject: [PATCH] Optimize Voxel Shape Merging
This method shows up as super hot in profiler, and also a high "self" time.
Upon analyzing, it appears most usages of this method fall down to the final
else statement of the nasty ternary.
Upon even further analyzation, it appears then the majority of those have a
consistent list 1.... One with Infinity head and Tails.
First optimization is to detect these infinite states and immediately return that
VoxelShapeMergerList so we can avoid testing the rest for most cases.
Break the method into 2 to help the JVM promote inlining of this fast path.
Then it was also noticed that VoxelShapeMergerList constructor is also a hotspot
with a high self time...
Well, knowing that in most cases our list 1 is actualy the same value, it allows
us to know that with an infinite list1, the result on the merger is essentially
list2 as the final values.
This let us analyze the 2 potential states (Infinite with 2 sources or 4 sources)
and compute a deterministic result for the MergerList values.
Additionally, this lets us avoid even allocating new objects for this too, further
reducing memory usage.

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] Prevent position desync in playerconnection causing tp
exploit
Caused the server to revert to the player's overworld coordinates
after teleporting into the end.
Sidenote: The underlying issue is that the move call can teleport
entities and do other things like kill the entity. In the future,
to fix all exploits derieved from this usually unexpected
behaviour, we need to move all of this dangerous logic outside
of the move call and into an appropriate place in the tick method.

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] Set cap on JDK per-thread native byte buffer cache
See: https://www.evanjones.ca/java-bytebuffer-leak.html
This is potentially a source of lots of native memory usage.
We are clearly seeing native usage upwards to 1-4GB which doesn't make sense.
Region File usage fixed in previous patch should of tecnically only been somewhat
temporary until GC finally gets it some time later, but between all the various
plugins doing IO on various threads, this hidden detail of the JDK could be
keeping long lived large direct buffers in cache.
Set system properly at server startup if not set already to help protect from this.

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.
