Patch documentation to come
Issues with the old system that are fixed now:
- World generation does not scale with cpu cores effectively.
- Relies on the main thread for scheduling and maintaining chunk state, dropping chunk load/generate rates at lower tps.
- Unreliable prioritisation of chunk gen/load calls that block the main thread.
- Shutdown logic is utterly unreliable, as it has to wait for all chunks to unload - is it guaranteed that the chunk system is in a state on shutdown that it can reliably do this? Watchdog shutdown also typically failed due to thread checks, which is now resolved.
- Saving of data is not unified (i.e can save chunk data without saving entity data, poses problems for desync if shutdown is really abnormal.
- Entities are not loaded with chunks. This caused quite a bit of headache for Chunk#getEntities API, but now the new chunk system loads entities with chunks so that they are ready whenever the chunk loads in. Effectively brings the behavior back to 1.16 era, but still storing entities in their own separate regionfiles.
The above list is not complete. The patch documentation will complete it.
New chunk system hard relies on starlight and dataconverter, and most importantly the new concurrent utilities in ConcurrentUtil.
Some of the old async chunk i/o interface (i.e the old file io thread reroutes _some_ calls to the new file io thread) is kept for plugin compat reasons. It will be removed in the next major version of minecraft.
The old legacy chunk system patches have been moved to the removed folder in case we need them again.

Also, restores un/loading worlds mid tick. This will not be officially supported API contract that such a routine is safe, and these restrictions may be restored in the future.

Logging into an unloaded world isn't going to end well.
This may fix the cases of people seeing errors about regionfiles
being closed, as loading chunks in an unloaded world will cause this
as the regionfile cache is closed but not cleared.

Vanilla uses a Random instance which is not thread safe inside of the
constructor for ServerLoginPacketListenerImpl, this is an issue because
instances of that class are created on the network worker threads, which
means that there is a potential (which we have reports confirming) that
multiple users logging on could trip this
in 1.19, mojang made it so that teleporations validate that an awaiting pos was
set in the server when teleporting, thus we need to ensure that this is set when
sending the player pos, otherwise the player will be kicked when the client sends
back the aknowledgement

* Refactor paper command
* Improve paper dumpitem output
* Register paper command permissions
Would be nice to add descriptions for these too, but that's an enhancement for another time
* Update MobcapsCommandTest fail message
* Notify on bad radius for fix light
* fixup rebase
We need chunks to actually have their light status future done to relight them, an imposter with for example only the empty future complete but with a light status cannot be relit.
getChunkForLighting gives the desired behavior and is the method used by the light engine, so updating fixlight to use it as well fixes#8115
The ZombieVillager#setConversionTime API method internally calls
startConversion which always broadcasts the entity event responsible for
playing the respective sound at the beginning of a conversion.
This is not always wanted by developers when modifying already
converting zombies in particular.
This commit expands the ZombieVillager interface with another overload
of the setConversionTime method that also takes a simple toggle flag
indicating whether or not the entity event should be published to the
world.
I do wanna add some leeway to the kick, if message was sent within 30-60
seconds of the last message, assume clock drift and just ignore the kick
(send a message? just silently ignore?), but, I'm not 100% on this one

These can be called while an entity is being added to the world,
and if the entity is being added from a chunk load context the
sync load will block indefinitely (because the chunk load context
is for completing the chunk to FULL).
This does raise questions about the current system for these
dynamic registrations, as it looks like there is _zero_ logic
to account for the case where the chunk is _not_ currently loaded
and then later loaded.
