More improvements to activation range, improve turtles
improved the water code so that immunity wont trigger if the entity
has the water pathfinder system active, so this improves support
for all entities that know how to behave in water.

Merged 2 EAR patches together, and removed an MCUtil method that
doesnt have a purpose anymore

Report errors correctly from FutureTasks
Anything that posts something to main thread was not
correctly reporting their errors to the logger, passing the
ExecutionExcetion instead of the cause. This resolves that,
as well as patches some simple cases of System.nanoTime where mojang
had used a LongSupplier to use a different method on client.

Fix lag caused by water mobs across the board - Fixes #1462
This update introduces Entity Activation Range for water mobs.

Activation Range has been one of my biggest performance improvements
I ever added to Minecraft, however "Entity is in Water" is an immunity
case that keeps an entity active.

This update ignores the water check for known water based mobs, allowing
them to actually go inactive.

In addition to that, a new config option was added to spigot.yml to go with
the rest of the entity-activation-range options to let you configure
aquatic mobs like fish, squid and dolphins separately.

This should overall fix all lag caused by water mobs.

26153def87 Fix FileIOThread concurrency issues (fixes #1505)
FileIOThread was using two volatile counters in order to track if
any pending work was in the queue, this causes potential concurrency
issues when this counter is updated from multiple threads, potentially
causing these counters to desync due to the unsafe volatile update

Add config options to paper.yml for Async Chunks and Shared Host Overrides
Shared Hosts have been concerned over the increased CPU usage that Async Chunks
has introduced. We understand that shared hosts can't allow 1 client
to abuse the systme resources depriving other servers of cpu time, so we've
added some configs to allow hosts to force some settings.

Hosts, you may set the following SYSTEM ENVIRONMENT VARIABLES (NOT JVM FLAGS)
to change some behavior:

PAPER_ASYNC_CHUNKS_SHARED_HOST_GEN=1   - Enable Single Threaded World Generation (capping CPU Usage
PAPER_ASYNC_CHUNKS_SHARED_HOST_GEN=2   - Disable Async Chunk Generation - Please do not do this!!!
  - Minecraft is moving towards asynchronousm per-world chunk generation itself. You need to prepare
  - for this, so please do not disable async chunk generation.

PAPER_ASYNC_CHUNKS_SHARED_HOST_LOAD=#  - Where # is Maximum number of threads to use on Chunk Loading
  - This is a max, so your end user can reduce it more too. I suggest no lower than 2. Minimum is 1.
  - These are usually much faster request, so outside of loading entire worlds, They usually do not
  - get as much load. Paperby default uses CPU Core count * 1.5, so this may default to a higher value
  - on shared host and you should override it with this value to say 2-4.

These settings will override your clients paper.yml options. Set as a system wide environment
variable to ensure all Paper clients respect your resource usage desires.

Resolves #1520

Disable use of Locks on main thread for DataPaletteBlock
This should greatly improve performance by using a No Op lock
while on the main thread.

Vanilla always had a write lock on write operations, but we added
a Read Lock during Async Chunks to make concurrent writes non fatal
for Async Chunks.

This means we added on a bunch of over head to all chunk read operations.

This corrects that, as well as disabling the write lock while on main thread.

It is a general rule that you do not touch a chunk async once it is loaded
into the world, as we never had locks on the chunk before 1.13 even.

So once we are on main, we don't expect concurrent access to begin with,
so we don't need the write locks either.

Optimize some light chunk access
light calculations repeatedly looks up the same chunk while going
down on the Y access. Pass the chunk to it to skip many round trips
to the map lookup process.

while the gains arent as big since we have last access cache, it
should hopefully avoid many callstacks of depth and improve inlining,
as well as avoids entering a synchronized code block.

The avoiding of entering synchronized section is the main goal here.

Optimize Spare Chunk loads to be removed faster
this has technically been a longer standing problem, but if an async
chunk loads after a chunk has been removed from the chunk map, it would
be treated as any other spare chunk and kept loaded until Chunk GC kicks in.

This fixes that, but also obsoletes ChunkGC in that anytime we load a spare
chunk (a chunk outside of any players view distance), we will immediately
mark it for unload.

This should reduce the amount of spare chunks loaded on a server.

Fix Village Loading Doors fix, add config option, hopefully fix farms
The patch was previously applied wrong, and still caused chunk loads.

Now, we will prevent it again, but also added a config option to
disable this optimization.

However, I also updated it so that doors are not removed if the chunk
the door is in is unloaded, so this should avoid breaking farms.

Fix Sending Chunks to Client - Fixes #1504
Vanilla has some screwy logic that doesn't send a chunk until
it has been post processed. This is an issue as post processing
doesn't occur until all neighbor chunks have been loaded.

This can reduce view distance while generating terrain, but also
cause bugs where chunks are never sent to the client.

This fix always sends chunks to the client, and simply updates
the client anytime post processing is triggered with the new chunk data.

Don't recheck type after setting a block
The server does a "Did my update succeed" check after setting
a blocks data to a chunk.

However, writes can not fail outside of a hard error or a
a race condition from multiple threads writing, which is
not something that should ever occur on the server.

So this check is pointless, as if it did occur, the server would
be having data corruption issues anyways.

This provides a small boost to all setType calls.

Fix issues with entity loss due to unloaded chunks
Vanilla has risk of losing entities by causing them to be
removed from all chunks if they try to move into an unloaded chunk.

This pretty much means high chance this entity will be lost in this scenario.

There is another case that adding an entity to the world can fail if
the chunk isn't loaded.

Lots of the server is designed around addEntity never expecting to fail for these reasons,
nor is it really logical.

This change ensures the chunks are always loaded when entities are
added to the world, or a valid entity moves between chunks.

Hopefully will fix issues #1496 and #1434

Optimize Light Recalculations
The server triggers light recalculations even if the new block
is the same as the old block. At this time, BlockData Properties
do not impact light calculations.

So the only way light should change, is if the block itself
changes from 1 block to another.

Additionally, as of 1.13, water now only blocks 1 light level
instead of 3, meaning that light level decreasing is the same as air.

This means, transitions between water and air also do not need
to recalculate light, which saves a TON of updates caused by
fluids flowing.

Ignore Dimension NBT field in Entity data
Minecraft is trying to set Dimension Objects based on a Dimension ID

Dimension ID's for custom worlds are dynamically allocate dand not guaranteed
consistent.

This removes checking the NBT data, as the Entity will always have its
DimensionManager set to the world it is being placed into.

This fixes corrupt entities breaking chunk saving in custom worlds.

Async Chunk Loading and Generation (#1397)
This restores Asynchronous Chunk Loading to 1.13, as well as adds Asynchronous Chunk Generation..

This provides a massive boost to server performance and should bring 1.13 back closer to 1.12 performance levels for pre generated worlds.

World Generation will now be faster overall than 1.12 since 1.12 did not have async generation.

Re-enable light queue toggle, optimize neighbor checks, add max queue time
light queue is actually buggy, so re-enabling the config.

however, if anyone is ok with the buggy behavior, made the max time lost due to

We want to get to making the ligth queue default if we can make it work perfectly.

also applying neighbor optimizations to use the faster method for light checks.

e8e994656b Avoid dimension id collisions (#1487)
getDimensionId() returns the dimension id - 1. So without this patch
we would reuse an existing dimension id, if some other dimension was
unloaded before.

In Spigot this is nearly invisible because DimensionManager has no equals(),
so dimension id collisions just create 2 worlds with the same dimension.

The PaperWorldMap (Added in
https://github.com/PaperMC/Paper/blob/master/Spigot-Server-Patches/0376-Optimize-Server-World-Map.patch ) changes this - Now the dimension is overwritten if there is some collision,
what causes players to teleport to incorrect worlds, World checks will no longer work
and many more evil things.

5d7bf5d57a Enable experimental ASM support for Java 11 plugins (#1480)
JEP 181 brings a new bytecode format for nest mates. ASM API 7 supports
this, but API 7 is still experimental. Attempting to load a Java 11
class that contains nest mates will cause an
UnsupportedOperationException, as API 6 can't handle them. This doesn't
really require any changes to the rest of the code, since this is just
related to ASM's visitor.

We want to use the stable API 6 for all other plugins, only using the
experimental API when required, so we check the class version first.

This should be removed as soon as ASM API 7 is stable.
