computeIfAbsent would leak as the entry
was never registered into the ttl map
This fixes that ,as well as redesigns cleaning to
not run on every manipulation, and instead to run clean
once per tick per expiring map.

94b8708a SPIGOT-4373: Item display colours are white by default
61668436 SPIGOT-4378: Fix mistakenly included code
When a mob was about to load a chunk to try to spawn in, we did not
increment the attempt counter, resulting in it being stuck in the mob
spawn loop for a long time and hanging servers.
Found some more unsafe operations in DataFixers.
Also replaced quite a few bad uses of Map.containsKey
containsKey is a common newbie mistake that "reads" cleaner, but
results in double the performance cost of all map operations as
containsKey in MOST cases where null values are not used is identical to get() == null
Considering how deep datafixers go in call stacks, with tons of map lookups,
this micro optimization could provide some gains.
Additionally, many of the containsKey/get/put style operations were
also a concurrency risk, resulting in multiple computation/insertions.

7033f180 Hoist out synchronisation from ChunkRegionLoader
Spigot Changes:
500ff5d4 Rebuild patches
Additional Paper changes:
Fixed Versioned World Folders to not synchronize on ChunkRegionLoader
Optimized Save Queue even more to use a Long2ObjectOpenHashmap for save map
Add World#getXIfLoaded to IWorldReader to expose it to more places
Adds an API to allow plugins to instruct a Mob to Pathfind to a Location or Entity
This does not do anything to stop other AI rules from changing the location, so
it is still up to the plugin to control that or override after another goal changed
the location.
Fixes GH-1417, GH-1424 (probably).
There are other issues in this area, including just how much a mess it
is but we will get to those when we get to those.

This restores vanilla behavior of allowing placed chests to retain any Block Entity Tag data.
Upstream added filtering to chests, breaking vanilla behavior, and preventing use of loot table chests as a reward mechanism.
Upon review, we can find no security risk in allowing players to place a chest with NBT data, as Spawn Eggs, Minecarts, command blocks etc all have their own checks.
Additionally, survival mode players, non op players can not create these items anyways. If a player has Creative or Op, they already have high levels of access.
Plus, Chests aren't the only inventory that could have free form items, so this filter was insufficient anyways.
The PluginManager incorrectly used synchronization on firing any event
that was marked as synchronous.
This synchronized did not even protect any concurrency risk as
handlers were already thread safe in terms of mutations during event
dispatch.
The way it was used, has commonly led to deadlocks on the server,
which results in a hard crash.
This change removes the synchronize and adds some protection around enable/disable

3eb8af23 SPIGOT-4348: Use online player for setting skull owner if possible
We are seeing issues with DataFixers being not thread safe in async chunks
and even in some spigot packet sending code.
There are a few more global objects that are mutated that need to
be synchronized to be safe for use over multiple threads.
There may be more cases, but these are extremely obvious ones.
This method will return the Block a player is looking at while taking into consideration the AABB of each block in the path.
For example, you can look through the 1/4 space of air in a Stair block and get the block behind it instead of the Stair block you are looking past.
Some things break from this, while this was trying to fix other things
since the thing this patch tried to fix still had problems and required
yet another fix, just going to remove this patch.
Fixes issue #1177
`MapMaker#weakKeys()` makes the `Map` use identity comparison for the keys, while also enabling the automatical removal of dropped classes from the cache.
The changes are the same as in #1399, except now the original patch is modified instead of a new one being created.
