Subject: [PATCH] Fix items vanishing through end portal
If the Paper configuration option "keep-spawn-loaded" is set to false,
items entering the overworld from the end will spawn at Y = 0.
This is due to logic in the getHighestBlockYAt method in World.java
only searching the heightmap if the chunk is loaded.
Quickly loading the exact world spawn chunk before searching the
heightmap resolves the issue without having to load all spawn chunks.

Subject: [PATCH] Optimise random block ticking
Massive performance improvement for random block ticking.
The performance increase comes from the fact that the vast
majority of attempted block ticks (~95% in my testing) fail
because the randomly selected block is not tickable.
Now only tickable blocks are targeted, however this means that
the maximum number of block ticks occurs per chunk. However,
not all chunks are going to be targeted. The percent chance
of a chunk being targeted is based on how many tickable blocks
are in the chunk.
This means that while block ticks are spread out less, the
total number of blocks ticked per world tick remains the same.
Therefore, the chance of a random tickable block being ticked
remains the same.

Subject: [PATCH] Pillager patrol spawn settings and per player options
This adds config options for defining the spawn chance, spawn delay and
spawn start day as well as toggles for handling the spawn delay and
start day per player. (Based on the time played statistic)
When not per player it will use the Vanilla mechanic of one delay per
world and the world age for the start day.

Subject: [PATCH] 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 serting 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.

Subject: [PATCH] Optimize PlayerChunkMap memory use for visibleChunks
No longer clones visible chunks which is causing massive memory
allocation issues, likely the source of Humongous Objects on large servers.
Instead we just synchronize, clear and rebuild, reusing the same object buffers
as before with only 2 small objects created (FastIterator/MapEntry)
This should result in siginificant memory use reduction and improved GC behavior.

Subject: [PATCH] Mid Tick Chunk Tasks - Speed up processing of chunk loads and
generation
Credit to Spotted for the idea
A lot of the new chunk system requires constant back and forth the main thread
to handle priority scheduling and ensuring conflicting tasks do not run at the
same time.
The issue is, these queues are only checked at either:
A) Sync Chunk Loads
B) End of Tick while sleeping
This results in generating chunks sitting waiting for a full tick to
complete before it will even start the next unit of work to do.
Additionally, this also delays loading of chunks until this same timing.
We will now periodically poll the chunk task queues throughout the tick,
looking for work to do.
We do this in a fair method that considers all worlds, not just the one being
ticked, so that each world can get 1 task procesed each before the next pass.
In a view distance of 15, chunk loading performance was visually faster on the client.
Flying at high speed in spectator mode was able to keep up with chunk loading (as long as they are already generated)

Subject: [PATCH] Don't move existing players to world spawn
This can cause a nasty server lag the spawn chunks are not kept loaded
or they aren't finished loading yet, or if the world spawn radius is
larger than the keep loaded range.
