On servers with plugins that constantly churn through scoreboards, there is a risk of degraded GC performance due to the number of scoreboards held on by weak references. Most plugins don't even need the (vanilla) functionality that requires all plugin scoreboards to be tracked by the server. Instead, only track scoreboards when an objective is added with a non-dummy criteria.
This is a breaking change, however the change is a much more sensible default. In case this breaks your workflow you can always force all scoreboards to be tracked with settings.track-plugin-scoreboards in paper.yml.

This reverts commit 7968c4f5c9.
Issues have been found post merge that sadly no one discovered during test builds.
Reverting for now until we can identify the issue and do another test round.
Trying to solve random hangs we've seen, ensuring that this part of code isnt the culprit
also fixing a vanilla bug reportedby PhiPro where tickets are released too early
hoping this reduces amount of incorrect light issues.
This greatly improves performance as it drastically reduces the amount
of Entities and Tile Entities that are "registered" into the world, as
purely "cached" chunks will no longer have their entities hanging out in the world.
Additionally this fixes our Entity Add To World and Entity Remove From World events
Those events have not been firing correctly since MC changed how chunks work here.
Now the server will only consider a chunk "loaded" if it's got a ticket putting
it at level 33 or lower, which matches the public Bukkit API.

Mojang precaches every single potential rewrite rule that could ever
exist on server startup. This includes rules from all the way back to versions from 6+ years ago.
This is the source of why the server hogs every CPU core at 100% every start.
For anyone who hard resets for updates or has force upgraded their entire world, this
results in completely wasted cpu cycles.
This massive CPU usage also delays server startup time.
We improve this by making "min version to precache" that defaults to a future version
so that no rewrite rules are precached.
someone who expects to be converting a lot chunks could theoretically set
-DPaper.minPrecachedDatafixVersion=<dataVersionConvertingFrom> as a startup
parameter and only build from that point on.
However this will likely never be needed as the server will still run
the same cache logic on demand when it's actually needed. The only
cost would be some delay on the FIRST chunk conversion, but paper already
runs chunk conversions on another thread so this will likely never be
a concern for TPS.
This patch will significantly reduce CPU use on startup, reduce memory usage,
and improve server startup time.

1.16.2 introduced 2 thread pools for Bootstrap vs main we didn't account for.
This also sets Bootstrap priority to be 1 less thread priority too so MC Main threads will always have
more priority specially on servers running multiple instances, since bootstrap tends to use up all CPU.

6f55306c4 SPIGOT-5794: Only skip interact event if position, hand and itemstack are equal
This is a pretty tiny update with very little changed. Recommended to update
from 1.16.2 ASAP as 1.16.2 is now no longer supported.
Plugins should mostly remain working as the NMS revision did not change.
Previously, Entity Activation Range only applied to the root entity of a vehicle chain.
If that vehicle is active, every entity as it's passenger would then tick.
This creates scenarios where EAR does not apply your desired ranges to passengers.
Additionally, any entity that was a passenger never had its inactiveTick method called
when the parent was inactive, creating behavioral desyncs.
This could of been a source of many villager issues when those villagers were in minecarts
as players commonly do.
Now we will process passengers checking their activation state independently of their vehicle
and if they are inactive, call their inactiveTick() method to ensure state remains consistent.
This also helps improve any desync issues with entity position of passengers too.
This also removes immunity for passenger/vehicles, so it should improve performance
of these minecart villagers too for EAR.
This makes it so entities that are passengers of other entities no longer count in the parents timings, as well as
tracks them as a separate timers per their tick status.
This lets you see how much time is spent in activated entities vs inactive (as inactive still has to do work)
Passengers is also tracked separately so you can identify "Villagers in Minecarts" vs roaming villagers, as
the lack of ability to move can impact their performance characteristics.
This will likely break any plugin that was naughty and directly messed with our internal timings as this
moves the timings to the EntityTypes object, speeding up creation of Entities to no longer store
a timing handler object per entity.
This will also change the output of the entities in timings to use internal ID's instead of class names.
If a plugin is broken by this, shame them for doing bad things. Paper will not fix it, they will have to fix it.

Spigot has been stripping the minecraft-server jar down in order to

fastutil. as we use fastutil and offer it as API, this is useless
to us, and creates headaches when it breaks builds due to spigots
version of this being installed.
