Subject: [PATCH] Do not process entity loads in CraftChunk#getEntities
This re-introduces the issue behind #5872 but fixes #6543
The logic here is generally flawed however somewhat of a nuance,
upstream uses managedBlock which is basically needed to process
the posted entity adds, but, has the side-effect of processing any
chunk loads which has the naunce of stacking up and either causing a
massive performance hit, or can potentially lead the server to crash.
This issue is particularly noticable on paper due to the cumulative efforts
to drastically improve chunk loading speeds which means that there is much more
of a chance that we're about to eat a dirtload of chunk load callbacks, thus
making this issue much more of an issue

Subject: [PATCH] Async catch modifications to critical entity state
These used to be here from Spigot, but were dropped with 1.17.
Now in 1.17, this state is _even more_ critical than it was before,
so these must exist to catch stupid plugins.

Subject: [PATCH] Fix setPatternColor on tropical fish bucket meta
Prior to this commit, the tropical fish bucket meta would set the body
color to the previous metas pattern colour when updating the pattern
colour.
This commit hence simply fixes this by using the proper body colour
value when updating the pattern color.

Subject: [PATCH] Do not overload I/O threads with chunk data while flush
saving
If the chunk count is high, then the memory used by the
chunks adds up and could cause problems. By flushing
every so many chunks, the server will not become
stressed for memory. It will also not increase the total
time to save, as flush saving performs a full flush at
the end anyways.

Subject: [PATCH] Preserve overstacked loot
Preserves overstacked items in loot tables, such as shulker box drops, to prevent the items
from being deleted (as they'd overflow past the bounds of the container)-- or worse, causing
chunk bans via the large amount of NBT created by unstacking the items.
Fixes GH-5140 and GH-4748.

This is because bukkit uses a separate head rotation field for yaw.

Subject: [PATCH] Fix upstreams block state factories
Sometimes, blocks are changed and then logic is called before the associated
tile entity is removed. When this happens, the factories were relying on the
block at the position, not the tile entity. This change prioritizes using the
tile entity type to determine the block state factory and falls back on
the material type of the block at that location.

Subject: [PATCH] Add root/admin user detection
This patch detects whether or not the server is currently executing as a privileged user and spits out a warning.
The warning serves as a sort-of PSA for newer server admins who don't understand the risks of running as root.
We've seen plenty of bad/malicious plugins hit markets, and there's been a few close-calls with exploits in the past.
Hopefully this helps mitigate some potential damage to servers, even if it is just a warning.
