2cd6ace7ab Only count Natural Spawned mobs towards natural spawn mob limit
This resolves the super common complaint about mobs not spawning.

This was ultimately a flaw in the vanilla count algorithim that allows
spawners and other misc mobs to count against the mob limit, which are
not bounded, and can prevent the entire world from spawning new.

I believe Bukkits changes around persistence may of actually made it
worse than vanilla.

This should fully solve all of the issues around it so that only natural
influences natural spawns.

5630b55346 Optimize Captured BlockEntity Lookup
upstream was doing a containsKey/get pattern, and always doing it at that.
that scenario is only even valid if were in the middle of a block place.

Optimize to check if the captured list even has values in it, and also to
just do a get call since the value can never be null.

0b77748b35 Fixes and additions to the spawn reason API
Expose an entities spawn reason on the entity.
Pre existing entities will return NATURAL if it was a non
persistenting Living Entity, SPAWNER for spawners,
or DEFAULT since data was not stored.

Additionally, add missing spawn reasons.

b71ceb5e0f BlockDestroyEvent
Adds an event for when the server is going to destroy a current block,
potentially causing it to drop. This event can be cancelled to avoid
the block destruction, such as preventing signs from popping when
floating in the air.

This can replace many uses of BlockPhysicsEvent

b2cbea9e63 PreSpawnerSpawnEvent
This adds a separate event before an entity is spawned by a spawner
which contains the location of the spawner too similarly to how the
SpawnerSpawnEvent gets called instead of the CreatureSpawnEvent for
spawners.

d50334d6e8 Configurable LootPool luck formula
Rewrites the Vanilla luck application formula so that luck can be
applied to items that do not have any quality defined.

See: https://luckformula.emc.gs for data and details
-----------

The rough summary is:
My goal was that in a pool, when luck was applied, the pool
rebalances so the percentages for bigger items is
lowered and smaller items is boosted.

Do this by boosting and then reducing the weight value,
so that larger numbers are penalized more than smaller numbers.
resulting in a larger reduction of entries for more common
items than the reduction on small weights,
giving smaller weights more of a chance

-----------

This work kind of obsoletes quality, but quality would be useful
for 2 items with same weight that you want luck to impact
in varying directions.

Fishing still falls into that as the weights are closer, so luck
will invalidate junk more.

This change will result in some major changes to fishing formulas.

-----------

I would love to see this change in Vanilla, so Mojang please pull :)

4f248b1b5b Fill Profile Property Events
Allows plugins to populate profile properties from local sources to avoid calls out to Mojang API
to fill in textures for example.

If Mojang API does need to be hit, event fire so you can get the results.

cad0c129c8 PreCreatureSpawnEvent
Adds an event to fire before an Entity is created, so that plugins that need to cancel
CreatureSpawnEvent can do so from this event instead.

Cancelling CreatureSpawnEvent rapidly causes a lot of garbage collection and CPU waste
as it's done after the Entity object has been fully created.

Mob Limiting plugins and blanket "ban this type of monster" plugins should use this event
instead and save a lot of server resources.

See: https://github.com/PaperMC/Paper/issues/917

eb20b0b160 API to get a BlockState without a snapshot
This allows you to get a BlockState without creating a snapshot, operating
on the real tile entity.

This is useful for where performance is needed

1d1c5a4493 use CB BlockState implementations for captured blocks
When modifying the world, CB will store a copy of the affected
blocks in order to restore their state in the case that the event
is cancelled. This change only modifies the collection of blocks
in the world by normal means, e.g. not during tree population,
as the potentially marginal overheads would serve no advantage.

CB was using a CraftBlockState for all blocks, which causes issues
should any block that uses information beyond a data ID would suffer
from missing information, e.g. Skulls.

By using CBs CraftBlock#getState(), we will maintain a proper copy of
the blockstate that will be valid for restoration, as opposed to dropping
information on restoration when the event is cancelled.

40654111d1 Do not submit profile lookups to worldgen threads
They block. On network I/O.

If enough tasks are submitted the server will eventually stall
out due to a sync load, as the worldgen threads will be

63de7b1ff6 Bound Treasure Maps to World Border
Make it so a Treasure Map does not target a structure outside of the
World Border, where players are not even able to reach.

This also would help the case where a players close to the border, and one
that is outside happens to be closer, but unreachable, yet another reachable
one is in border that would of been missed.

db2502d732 Sanitise RegionFileCache and make configurable
RegionFileCache prior to this patch would close every single open region
file upon reaching a size of 256.
This patch modifies that behaviour so it closes the the least recently
used RegionFile.
The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap).
The maximum size of the RegionFileCache is also made configurable.

e2accd8d62 Configurable Chunk Inhabited Time
Vanilla stores how long a chunk has been active on a server, and dynamically scales some
aspects of vanilla gameplay to this factor.

For people who want all chunks to be treated equally, you can chose a fixed value.

This allows to fine-tune vanilla gameplay.
