If the server tick length is high, then the amount of time
available to process chunk tasks inbetween ticks is low. As a
result, chunk loading and generation may appear to slow down.
To ensure that chunk tasks are always processed, we add logic to
execute chunk tasks during tile entity tick, entity tick, chunk
random ticking, and scheduled block/fluid ticking. The mid-tick task
execution is timed so that it is not prioritised over the server
tick.
While the null UUID is almost certainly an error, the old
implementation did not NPE as it used a plain HashMap for lookup
by UUID, whereas we use a ConcurrentHashMap which will NPE on
null keys.
The unload queue stored the chunks in the same section as
the chunk coordinate, when it needed to apply the unload shift.
Additionally, change the default region shift to the ticket
propagator shift as there is no benefit to using a low region
shift since no regionizing is occuring. This makes the unload
queue shift 6, which should reduce the number of sections to deal
with while processing unloads.
Somehow, a chunkholder is present in the unload queue after
it has been unloaded. It is likely that this is a result of
adding the chunk holder to the unload queue while it is
unloading. However, that should not be possible.
To find out where it is being added to the unload queue, track
the last stacktrace which adds to the unload queue and check
on chunk holder remove if the holder is present in the unload queue
and log the stacktrace.
Remove utilities that are unused, as well as replacing
the full chunk map with a concurrentutil implementation.
Additionally, fix the addition/removal of chunks to/from the
full chunk map so that getChunkIfLoaded correctly returns a
non-null chunk when calling the load or unload events.
The upstream implementation is returning true for non-full chunks.
This fix is not ideal since the new chunk system doesn't have a region file/chunk status patch. May want to be revisited before a non-experimental release.
Implementations for ChunkStatuses below FULL are supposed to always
return ProtoChunk instances. However, since we used the last completed
status, it could return LevelChunk.
To resolve this, follow Vanilla behavior of tracking chunk
completions by status and replace old ProtoChunk statuses with
ImposterProtoChunk when the chunk generates to FULL.
Additionally, implement an optimisation for retrieving full chunks
by storing a map of pos -> LevelChunk. This requires only a simple
map lookup to occur for full chunks which are loaded.

The method sadly is not usable in 1.21 without a player as all of an
enchantments attribtue modifiers rely on a base value supplied by a
player. The method could only offer a rough estimate based on some
default values, however a better method for this should be added down
the line rather than trying to force such logic into the existing one.
A long standing bug in spigot and its derivatives was the fact that
players taking damage while blocking with a shield would not receive
invulnerability, while they do in vanilla.
This enabled the pvp technique of disabling a shield and immediately
attacking again to knock a player into the air.
While upstream fixed this and properly aligned itself with vanilla
damage logic (in this specific case) changing such long standing
behaviour has some downsides.
To allow players used to this specific bug to still use it, this patch
introduces a configuration option to re-introduce said bug.
As there is no easy way to *only* re-add this bug, the option is found
in the unsupported section as it may introduce other damage related
disparity from vanilla.
Previously would stream and optionally filter out all entries in the
enchantment registry.
Moves it to using the empty optional if treasure is allowed, leaving the
logic to EnchantmentHelper.

Chunk system patch was refactored to take advantage of
newer ConcurrentUtil's concurrent long hash table (which
fixes hash collisions caused by chaining fastutil's long hash
and CHM's hash) plus some other minor improvements.
The chunk system was also merged with Starlight, which mostly
provides a small improvement to ThreadedLevelLightEngine#checkBlock
as the scheduling was rewritten.

The player sample uses game profile internally, but discards everything but the name and uuid and does not follow player profile restrictions, so it doesn't make sense to use that in the event.
