ba71d372a5 Fix shield disable inconsistency
In vanilla, if the damage source is tagged as a projectile,
it will not disable the shield if the attacker is holding
an axe item.

15fcde4b3c Fix NPE on null loc for EntityTeleportEvent
EntityTeleportEvent#setTo is marked as nullable and so is the
getTo method. This fixes the handling of a null "to" location
by treating it the same as the event being cancelled. This is
already existing behavior for the EntityPortalEvent (which
extends EntityTeleportEvent).

ddbfcd4403 Restore vanilla entity drops behavior
Instead of just tracking the itemstacks, this tracks with it, the
action to take with that itemstack to apply the correct logic
on dropping the item instead of generalizing it for all dropped
items like CB does.

fff5d44a12 Don't fire sync events during worldgen
Fixes EntityPotionEffectEvent
Fixes EntityPoseChangeEvent

Asynchronous chunk generation provides an opportunity for things
to happen async that previously fired synchronous-only events. This
patch is for mitigating those issues by various methods.

Also fixes correctly marking/clearing the entity generation flag.
This patch sets the generation flag anytime an entity is created
via StructureTemplate before loading from NBT to catch uses of
the flag during the loading logic. This patch clears the generation
flag from an entity when added to a ServerLevel for the situation
where generation happened directly to a ServerLevel and the
entity still has the flag set.

d648e75653 Correctly shrink items during EntityResurrectEvent
The EntityResurrectEvent logic is supposed to locate a totem of undying
in any of the interaction slots of the player inventory and then, if the
called EntityResurrectEvent is not cancelled, shrink that item by 1,
usually reducing it to zero.

For this, the logic iterates over the items in the interaction slots and
breaks out the loop if a totem of undying was found.
However, even if no totem of undying was found, the iteration item stack
variable remains as a refernce to the last interaction slot probed.

Plugins uncancelling a EntityResurrectEvent, which is published
pre-cancelled to listeners if no totem of undying could be found,
would hence cause the server logic to shrink completely unrelated items
found in, at the writing of this patch, the players off hand slot.

This patch corrects this behaviour by only shrinking the item if a totem
of undying was found and the event was called uncancelled.

c593e8510e Improve and expand AsyncCatcher
Log when the async catcher is tripped
  The chunk system can swallow the exception given it's all
  built with completablefuture, so ensure it is at least printed.

Add/move several async catchers

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.

3ab3613d10 Fix PlayerItemConsumeEvent cancelling properly
When the active item is not cleared, the item is still readied
for use and will repeatedly trigger the PlayerItemConsumeEvent
till their item is switched.
This patch clears the active item when the event is cancelled

4b1f23c2e8 Fix item duplication and teleport issues
This notably fixes the newest "Donkey Dupe", but also fixes a lot
of dupe bugs in general around nether portals and entity world transfer

We also fix item duplication generically by anytime we clone an item
to drop it on the ground, destroy the source item.

This avoid an itemstack ever existing twice in the world state pre
clean up stage.

So even if something NEW comes up, it would be impossible to drop the
same item twice because the source was destroyed.

3d63d68ecb Don't run entity collision code if not needed
Will not run if:
Max entity cramming is disabled and the max collisions per entity is less than or equal to 0.
Entity#isPushable() returns false, meaning all entities will not be able to collide with this
entity anyways.
The entity's current team collision rule causes them to NEVER collide.

373c8ff0b2 force entity dismount during teleportation
Entities must be dismounted before teleportation in order to avoid
multiple issues in the server with regards to teleportation, shamefully,
too many plugins rely on the events firing, which means that not firing
these events caues more issues than it solves;

In order to counteract this, Entity dismount/exit vehicle events have
been modified to supress cancellation (and has a method to allow plugins
to check if this has been set), noting that cancellation will be silently
surpressed given that plugins are not expecting this event to not be cancellable.

This is a far from ideal scenario, however: given the current state of this
event and other alternatives causing issues elsewhere, I believe that
this is going to be the best soultion all around.

Improvements/suggestions welcome!

04afedcccf Improve death events
This adds the ability to cancel the death events and to modify the sound
an entity makes when dying. (In cases were no sound should it will be
called with shouldPlaySound set to false allowing unsilencing of silent
entities)

It makes handling of entity deaths a lot nicer as you no longer need
to listen on the damage event and calculate if the entity dies yourself
to cancel the death which has the benefit of also receiving the dropped
items and experience which is otherwise only properly possible by using
internal code.

d2f4d82ce2 Cap Entity Collisions
Limit a single entity to colliding a max of configurable times per tick.
This will alleviate issues where living entities are hoarded in 1x1 pens

This is not tied to the maxEntityCramming rule. Cramming will still apply
just as it does in Vanilla, but entity pushing logic will be capped.

You can set this to 0 to disable collisions.

5764c71185 Disable Scoreboards for non players by default
Entities collision is checking for scoreboards setting.
This is very heavy to do map lookups for every collision to check
this setting.

So avoid looking up scoreboards and short circuit to the "not on a team"
logic which is most likely to be true.

28c8009a16 Entity Activation Range
This feature gives 3 new configurable ranges that if an entity of the matching type is outside of this radius of any player, will tick at 5% of its normal rate.

This will drastically cut down on tick timings for entities that are not in range of a user to actually be "used".
This change can have dramatic impact on gameplay if configured too low. Balance according to your servers desired gameplay.
