Improve Async Login to avoid firing in middle of Entity Ticking
If a sync load was triggered, it would process pending join events,
causing them to be added to the world in the middle of the entity ticking
process.

This caused their add to be queued instead of immediate, causing
"Illegal Tracking" errors.

This schedules it to fire at the players next Connection Tick, which
is exactly where this entire process use to run anyways.

Also added missing tab complete and syntax for syncloadinfo debug command

Implement Brigadier Mojang API
This is the start of a new module for Paper to add support for API's
that interface Mojang API's directly.

This allows us to version properly by MC version incase Mojang makes any major breaking changes.

It also lets us separate Mojang API's from Paper-API so our downstream friends at Glowstone
will not have to worry about Mojang code.

Adds AsyncPlayerSendCommandsEvent
  - Allows modifying on a per command basis what command data they see.

Adds CommandRegisteredEvent
  - Allows manipulating the CommandNode to add more children/metadata for the client

Entity Activation Range 2.0! Major improvements to restoring behavior
Calling this 2.0 as it's a pretty major improvement with more knobs to twist.

This update fixes many things. The goal here is to restore vanilla behavior to some degree.
Instead of permanent inactive pools of animals, let them show some signs of life some....

Yes this may reduce performance compared to before, but I hope it is minimal. Got to find a balance.
Previous EAR logic really compromised vanilla behavior of mobs. This tries to restore it.

Changes:

1) All monsters are now classed as Monster. Mojang has an interface, we should use it.
   - This now includes Shulker, Slimes, see #2 for Phantom and Ghast
2) Villagers and Flying Monsters now have their own separate activation range configs.
   - Villagers will default to your Animals config
3) Added a bunch of more immunities
   - Brand new entities are immune for a few seconds
   - Entities that recently traveled by portal are immune for few seconds
   - Entities that are leashed to a player are immune
   - Ender Signals are immune
   - Entities that are jumping, climbing, dying (lol) are immune
   - Minecarts are now always immune to the movement restriction
4) Villagers immunity received major overhaul...
   - Now has many immunities for Villager activities to let them
     do their work then go back inactive
   - Such as interacting with doors and workstations should be more normal now
   - Raids will trigger immunities, in that villagers will run and hide when bell rings.
   - Raid should keep the entire village immune during the raid to keep gameplay mechanics
     You can disable raids by game rule if you dont want raids

Then the big one.....

Wake Up Inactive Entities:
One issue plagueing "farms" is that we no longer even let entities move now.
Entities become lifeless.

A new system has been introduced to wake up inactive entities every so often, to let
them stretch their legs, eat some food, play with each other and experience the good entity life.

Animals, Villagers, Monsters (Includes Pillagers), and Flying Monsters will now wake up every
so often after staying inactive for a very long. This grants them a temporary immunity, that
the goal is they will then find "stuff to do" by having a longer activity window.

How many to wake up, how often they wake up, and for how long they wake up are all configurable.

Current EAR Immunities really don't give some entities enough of a window to find work
to then keep them immune for the work to even start. This system should help that.

We will only wake up a few entities per tick on the first wave, restoring 1 per type per world per tick.

So say you have 10 monsters qualify for inactive wake up, all 8 will wake up on the first eligible tick,
and then the 9th will wake up on next tick, 10th on next tick.

If for 5 ticks no more inactive wake up, our buffer will have built back up to 5, and then 5 can go next needed tick.

This basically incrementally wakes them up, preventing too many from waking up in a single tick, to reduce impact to TPS.

Fix Tracking Range mismatch on Vehicle/Passenger checks
This was missing Entity Tracking Range support, creating different
values in this section vs normal section.

Concerned this might of caused some carnage on tracker if this code says
"Yes you should track this player 500 blocks away from you on a horse" and then
the other check uses the normal value.

Improve blocking players from opening inventories while sleeping
This is friendlier to plugins as far as the plugin is concerned,
the inventory did open and immediately closed.

We avoid sending the packet to client so they don't see the window
flash either.

If a plugin wants to avoid wasteful fake opens, they should check
that the player is not sleeping before opening the inventory.

Clean up Timings and Async Chunk Configs
Renames a bunch of timings to be more appropriate for the new environment.

Many things dealt with sync loads which wasn't correct anymore.

Improve mid tick chunk loading, Fix Oversleep, other improvements
Process loads outside of any canSleep check. Original intent was to
only apply those restrictions to generations but realized I had some
checks higher up the call chain.

Reworked the back off strategy to just run every 1 millisecond per world,
and to apply the per tick limit to generations only.

This guarantees that your chunk will load with at most around 1ms delay.

Additionally, fire midTick processing in a few more places, notably the
oversleep section so we can keep processing loads here too which has
a large up to 50ms window...

Speaking of oversleep, we had a bug in our implementation changes for
Timings that caused oversleep to not sleep the correct amount.

Because we now moved it into the NEXT tick instead of THIS tick, the
value of nextTick had already been increased to +50ms, resulting in
the risk of sleeping more than it should, but, more importantly, this
caused every task that was trying to NOT run during oversleep to actually
run during oversleep.

This is now fixed.

Another small tweak is to the /tps command, to no longer show the star when
TPS is right at 20.

Due to ineffeciencies in the sleep precision, TPS is commonly 20.02.
This causes the star to show up almost constantly, so now only show it if
we actually hit a real "catchup".

This commit also improves the changes to the CallbackExecutor, in that
it now is also recursion safe.

It was possible that the executor could run tasks out of desired order
if the executor task scheduled more executor tasks.

We solve this by ensuring new additions do not enter the currently iterated queue.

Each depth level will have its own queue.

Fix numerous item duplication issues 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.

This should make us more forward proof on preventing dupes.

These dupes have been in for years at this point, they aren't new...
Everyone knows about them and are mitigating with plugins atm breaking gameplay.

so better to make it clear its fixed in the messaging.

I am submitting this to Mojang.

Fix Longstanding Broken behavior of PlayerJoinEvent
For years, plugin developers have had to delay many things they do
inside of the PlayerJoinEvent by 1 tick to make it actually work.

This all boiled down to 1 reason why: The event fired before the
player was fully ready and joined to the world!

Additionally, if that player logged out on a vehicle, the event
fired before the vehicle was even loaded, so that plugins had no
access to the vehicle during this event either.

This change finally fixes this issue, fully preparing the player
into the world as a fully ready entity, vehicle included.

There should be no plugins that break because of this change, but might
improve consistency with other plugins instead.

For example, if 2 plugins listens to this event, and the first one
teleported the player in the event, then the 2nd plugin actually
would be getting a valid player!

This was very non deterministic. This change will ensure every plugin
receives a deterministic result, and should no longer require 1 tick
delays anymore.

Fix Chunk Post Processing deadlock risk
See: https://gist.github.com/aikar/dd22bbd2a3d78a2fd3d92e95e9f28dc6

as part of post processing a chunk, we can call ChunkConverter.

ChunkConverter then kicks off major physics updates, and when blocks
that have connections across chunk boundries occur, a recursive risk
can occur where A updates a block that triggers a physics request.

That physics request may trigger a chunk request, that then enqueues
a task into the Mailbox ChunkTaskQueueSorter.

If anything requests that same chunk that is in the middle of conversion,
it's mailbox queue is going to be held up, so the subsequent chunk request
will be unable to proceed.

We delay post processing of Chunk.A() 1 "pass" by re stuffing it back into
the executor so that the mailbox ChunkQueue is now considered empty.

This successfully fixed a reoccurring and highly reproduceable crash
for heightmaps.
