Yatopia/patches/removed/server/0064-Async-entity-tracking.patch
Mykyta Komarnytskyy 2e894832ed Remove unstable/unnecessary patches 
- Removed async entity tracking, as this is not a good implementation and has caused issues numerous times
- Removed "0037-Load-also-the-chunk-that-you-re-teleporting-to" as it does not fix the core problem
- Removed "0048-Fix-villager-dupe" as it was deemed unnecessary

Subject: [PATCH] Async entity tracking
Entity tracking is done the same way, but asynchronously.
Lowers the MSPT and NSPT by a lot.
The changes made:
Synchronised the trackedEntities map in PlayerChunkMap, also added additional lock to it.
Created a tracker executor which is processing the track queue asynchronously.
A minor change was to replace 2 array lists with our GlueList implementation.
Certain stuff had to be ensured to be called on the main thread when the tracker entry was ticked due to how
the game's code works and due to how bukkit's event system works.
Entity tracking is some of the heavy stuff the server does. Making this async is trivial for making the performance
go up.
