Optimize NibbleArray to use pooled buffers
Massively reduces memory allocation of 2048 byte buffers by using
an object pool for these.

Uses lots of advanced new capabilities of the Paper codebase :)

Targets 3072 * 8 buffers per 1GB of heap memory up to a max consideration
of 6GB of heap (any more over 6GB won't give more nibble pool)

You can control the 3072 number by setting -DPaper.nibbleBucketSize=2048

Remember this number is * 8 then * heap memory in GB

That is 98304 objects for 4GB of memory, at 2064 bytes roughly, meaning 194MB

You may also control max number of pooled objects directly instead of any
dynamic calculation using -DPaper.maxNibblePoolSize=1024000

While this will use more old generation by a tad bit, allocation rate will drop
significantly, causing less young generation GC's.

This commit has gone through extensive testing for over a day and confident
it no longer has any issues with light corruption.

Foundational work for Future Memory usage improvements
This commit doesn't do much on its own, but adds a new Java Cleaner API
that lets us hook into Garbage Collector events to reclaim pooled objects and
return them to the pool.

Adds framework for Network Packets to know when a packet has finished dispatching
to get an idea when a packet is done sending to players.

Rewrites PooledObjects impl to properly respect max pool size and remove
almost all risk of contention.

Bumps the Paper Async Task Queue to use 2 threads, and properly shuts it down on shutdown.

Handle CraftPlayer#setSpectatorTarget better
Use a proper teleport for teleporting to entities in different
worlds.

Validate that the target entity is valid and deny spectate
requests from frozen players.

Also, make sure the entity is spawned to the client before
sending the camera packet. If the entity isn't spawned clientside
when it receives the camera packet, then the client will not
spectate the target entity.

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.

Optimize Pathfinder - Remove Streams / Optimized collections
I utilized the IDE to convert streams to non streams code, so shouldn't
be any risk of behavior change. Only did minor optimization of the
generated code set to remove unnecessary things.

I expect us to just drop this patch on next major update and re-apply
it with the IDE again and re-apply the collections optimization.

Optimize collection by creating a list instead of a set of the key and value.

This lets us get faster foreach iteration, as well as avoids map lookups on
the values when needed.

Optimize Hoppers - Major performance improvement
Removed streams from hoppers and also fixed a mistake in the logic.
When this patch was ported to 1.14/1.15, a line of code was put in
the wrong place which disabled a significant portion of the improvement.

Replaced usages of streams in isEmpty and itemstack checks
Replaced usage of streams in pulling loop
Replaced usage of streams in Lootable Inventory isEmpty() check
Only check for refilling Lootable Inventory when accessing first slot, not all

All of these in general were pretty significant hits, so this single commit
is going to cause tacos to magically appear in front of you every day.

Wait for Async Tasks during shutdown

Adds a 5 second grace period for any async tasks to finish and warns

Ensure Entity AABB's are never invalid
If anything used setPositionRaw, it left potential for an AABB
to be left stale at their old location, which could cause massive
AABB boxes if movement ever then got called on the new position.

This guarantees any time we set the entities position, we also
update their AABB.

Fix teleporting onto a chunk line
Obscure detail in that if you teleport right on a chunk line, it
adds +1 to your collision check and will check the unloaded neighbor.

but the call to load the chunk then returned null if it was pending unload, such
as the load we did in Player List

However we want gen=true for players here anyways, so use getType

Optimize Collision to not load chunks
The collision code takes an AABB and generates a cuboid of checks rather
than a cylinder, so at high velocity this can generate a lot of chunk checks.

Treat an unloaded chunk as a collision for entities, and also for players if
the "prevent moving into unloaded chunks" setting is enabled.

If that setting is not enabled, collisions will be ignored for players, since
movement will load only the chunk the player enters anyways and avoids loading
massive amounts of surrounding chunks due to large AABB lookups.

Improve BlockPosition hashCode/equals
Actually showed up in profiling as decent time spent here...

Noticed y/z was missing its final that it use to have, when x had it. some how
must of got messed up on some update. though people suggest this shouldn't of
mattered anyways, but lets put it back for safety.

Added cache of hashcode, as well as optimized the hash code using larger primes.
Also stored the long value of the x/y/z so that for equals we can compare a single long,
as well as have that long value cached for .asLong()

Force Plugins that use delayed tasks for init back in their place
Will now run those tasks just before we print "Done" so that startup
time is appropriately accounted for a plugin, as well as will no longer
trip the watchdog on startup.

Any plugin that tries to bypass this is just going to then trip watchdog
on Spigot too, so don't you dare.

Stop trying to cheat the delay your plugin added to startup time.

This isn't a behavior change because the first thing the tick does....
was run these tasks....

So it's just moving it slightly a few lines to be before a watchdog tick and
to account for it in "Done" time.
