Current Chunk for Entity and Block Entities, counts by entity type This enables us a fast reference to the entities current chunk instead of having to look it up by hashmap lookups. We also store counts by type to further enable other performance optimizations in later patches.

Replace HashSet with fastutil's ObjectOpenHashSet in HashTreeSet HashSet sometimes uses compareTo() instead of equals() and this breaks the comparison of net.minecraft.server.NextTickListEntry (the only place where HashTreeSet is used). In this cases duplicate entries could be added to the HashSet of HashTreeSet, because NextTickListEntry.compareTo() does not return 0, even if NextTickListEntry.equals() returns true. ObjectOpenHashSet never uses compareTo(), so the inconsistencies of NextTickListEntry cause no problems. Fixes https://github.com/PaperMC/Paper/issues/588

Subject: [PATCH] Replace HashSet with fastutil's ObjectOpenHashSet in
HashTreeSet
HashSet sometimes uses compareTo() instead of equals() and this breaks the comparison of net.minecraft.server.NextTickListEntry (the only place where HashTreeSet is used).
In this cases duplicate entries could be added to the HashSet of HashTreeSet, because NextTickListEntry.compareTo() does not return 0, even if NextTickListEntry.equals() returns true.
ObjectOpenHashSet never uses compareTo(), so the inconsistencies of NextTickListEntry cause no problems.

Fix issues with getBlockState(false) not loading Tile Entity data This only impacted people who used our useSnapshots new API in a plugin, which obviously was no one as the data result was completely broken. Merged the NPE check patch into mine since it has to handle it too.
