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.

CraftBukkit Changes:
dc69d2b3 Fix unbound shaped recipe ingredients
ForgeFlower is better than Spigots FernFlower at decompiling the source.
However, in order to maintain the CraftBukkit patches, we must keep
using spigots for the primary.
However, for any file that we import on top of Spigots imported files
there is nothing stopping us from using better decompiled files.
So these changes will use ForgeFlower to maintain a better set of
decomped files, so anything we add on top of Paper can start off
in a better spot.
Fixes GH-1389
Because we are no longer enabling creepers to rapidly change status
every tick, in order to prevent event spam, their datawatcher value
ends up negative.
This datawatcher value is used to increment the fuseTicks within the
creeper tick. Because the value is negative, it is constantly zero'd
and therefore never incremented, instead acting the same as creepers
that aren't ignited.
We can just as easily increment this ourselves when the creeper is
ignited, so that's what we'll do.
Uses optimized check to avoid major locks and large method.
Will improve inlining across many hot methods.
Improve getBrightness to not do double chunk map lookups.

Also fixes some bugs in ours
Ultimately they both are near the same, but ours is behind the synchronized gate.
Mojangs is mixed behind 2 different synchronization contexts (chunks can lock 2 different objects)
Mojang also blindly unsets the ref on any chunk unload, not just if its the one being pointed to.

Replaces PR #1161 for 1.13
Resolves#930
Adds new slime pathfinder related events. All events can be cancelled.
- `SlimePathfindEvent` is the base event of all added events. Cancelling this event will cancel all pathfinders.
- `SlimeWanderEvent` is called when slimes wander around by either swimming or moving/jumping forward. Cancelling this event will prevent slimes from moving around and jumping, but they will still look around and target players.
- `SlimeSwimEvent`is called when slimes are swimming in water/lava. Cancelling will prevent the slimes from moving/jumping in water/lava.
- `SlimeChangeDirectionEvent` is called when a slime changes directions. It contains the new `yaw` position the slime wants to change to, and it can be set to another value. Cancelling this event will prevent slimes from changing directions (except for when targeting players).
- `SlimeTargetLivingEntityEvent` is called when a slime targets a player. NMS uses EntityLiving here so it is named this. Contains the LivingEntity the slime has targeted. Cancelling this event will prevent the slime from targeting the entity and will make it lose current focus.
Adds `Slime#canWander()` and `Slime#setWander(boolean)` for a more persistent control (does not persist server restarts) over all 4 pathfinder types without the spammy event having to be cancelled a bajillion times a second.
