Subject: [PATCH] Prioritise own classes where possible
This adds the server property `Paper.DisableClassPrioritization` to disable
prioritization of own classes for plugins' classloaders.
This value is by default not present, and this will therefore break any
plugins which abuse behaviour related to not using their own classes
while still loading their own. This is often an issue with failing to
relocate or shade properly, such as when shading plugin APIs like Vault.
A plugin's classloader will first look in the same jar as it is loading
in for a requested class, then load it. It does not re-use other
plugins' classes if it has the chance to avoid doing so.
If a class is not found in the same jar as it is loading for and it does
find it elsewhere, it will still choose the class elsewhere. This is
intended behaviour, as it will only prioritise classes it has in its own
jar, no other plugins' classes will be prioritised in any other order
than the one they were registered in.
The patch in general terms just loads the class in the plugin's jar
before it starts looking elsewhere for it.

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] 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.
