All generated chunks should be loadable
Some chunks that need conversion may fail the loadChunks pass, and
end up entering the world gen code to finish processing.

We solved this on the API level before, but this needs to apply to
all chunk loads when gen=false

Rework Async Chunks API in prep for merge, add utility
This adds a new Future based, Consumer<Chunk> based, and ability
to control whether or not to generate to the Async Chunk API.

Until Async Chunks merges, these API's are still synchronous, but
this commit will allow plugins to start using the API's in use
with the Async Chunks beta.

Sync Player Position to Vehicles
Player Positions could become desynced with their vehicle resulting
in chunk conflicts about which chunk the entity should really be in.

MC-134115: Fix Double Chest Chunk Conversion Error
A bug with double chest conversion would lead to data
loss from chunks if they crossed chunk boundries.

This fixes the issue.

It should now be safe to upgrade worlds to 1.13.1

1e66b061fa Add a separate PreSpawnerSpawnEvent (#1455)
This event extends the PreCreatureSpawnEvent and includes the position
of the spawner that spawned the entitiy. (similarly to how the
SpawnerSpawnEvent contains the spawner's BlockState).

This one doesn't include the state though as getting the block and
generating that snapshot is a bit wasteful.

Make a copy for worldloadevent to avoid como's - fixes #1453
If you try to load a world inresponse to another world loading,
a concurrent modification exception will throw.

This avoids that by making a defensive copy of the list for the server init stage.

you might  want to do this if you want to guarantee your world loads
immediately after the vanilla worlds before another plugin has a chance
to load worlds during POST_WORLD plugin stage.

Optimize Server World Map
Minecraft moved worlds to a hashmap in 1.13.1.
This creates inconsistent order for iteration of the map.

This patch restores World management to be back as an Array.

.values() will allow us to iterate as it was pre 1.13.1 by
ArrayList, giving consistent ordering and effecient iteration performance.

KeySet and EntrySet iteration is proxied to the List iterator,
and should retain manipulation behavior but nothing should be doing that.

Getting a World by dimension ID is now back a constant time operation.

Hopefully no other plugins try to mess with this map, as we are only handling
known NMS used methods, but we can add more if naughty plugins are found later.

Multiverse was tested with this and no breakage.

Support Overriding World Seeds - Closes #350
Allows you to add to paper.yml

seed-overrides:
  world_name: some seed value

This will ignore every where a seed is set/created/loaded and force
a world to use the specified seed.

This seed will end up being saved to the world data file, so it is
a permanent change in that it won't go back if you remove it from paper.yml

Use BigDecimal to improve accracy of TPS results - long live 20 TPS!
It's always been commonly said to 'ignore' that TPS was '19.X', that
it was fine.

I suspect that the inaccuracy of floating point math resulted in us
losing precision over time, making it difficult to actually get back to 20,
as you know the fun 0.1 + 0.1 ... 9 more times != 1 problem.

BigDecimal supports working with doubles with higher precision.

This change makes it so our RollingAverage class maintains all of the data
using BigDecimal and using BigDecimal arithematic operations.

This ensures we have extremely high precision, enabling us to
actually be able print '20 TPS' when TPS is perfect.

Fix loop risk in mob spawning around unloaded chunks

Concurrency and Performance Improvements to DataFixers
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.

c755f90933 Allow chests to be placed with NBT (#1425)
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.

Remove deadlock risk in firing async events
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
