This fixes exploits that let players destroy bedrock by Pistons, explosions
and Mushrooom/Tree generation.
These blocks are designed to not be broken except by creative players/commands.
So protect them from a multitude of methods of destroying them.
A config is provided if you rather let players use these exploits, and let
them destroy the worlds End Portals and get on top of the nether easy.

I swear the crap that stuff will abuse to make stuff happen is insane.
Hash codes apparently changing behavior of stuff based on its value, so
reverting 2d401d2dfbFixes#3346Fixes#3341
I utilized the IDE to convert streams to non streams code, so shouldn't
be any risk of behavior change. Only did minor optimization of the
generated code set to remove unnecessary things.
I expect us to just drop this patch on next major update and re-apply
it with the IDE again and re-apply the collections optimization.
Optimize collection by creating a list instead of a set of the key and value.
This lets us get faster foreach iteration, as well as avoids map lookups on
the values when needed.
Removed streams from hoppers and also fixed a mistake in the logic.
When this patch was ported to 1.14/1.15, a line of code was put in
the wrong place which disabled a significant portion of the improvement.
Replaced usages of streams in isEmpty and itemstack checks
Replaced usage of streams in pulling loop
Replaced usage of streams in Lootable Inventory isEmpty() check
Only check for refilling Lootable Inventory when accessing first slot, not all
All of these in general were pretty significant hits, so this single commit
is going to cause tacos to magically appear in front of you every day.

If you hate taco's, you're not allowed to use this improvement.
Also ignore the renames, pulled a lot of PR's.
Server.reload() had this logic to give time for tasks to shutdown,
however shutdown did not...
Adds a 5 second grace period for any async tasks to finish and warns
if any are still running after that delay just as reload does.
Closes#3337
If anything used setPositionRaw, it left potential for an AABB
to be left stale at their old location, which could cause massive
AABB boxes if movement ever then got called on the new position.
This guarantees any time we set the entities position, we also
update their AABB.
We store a reference to the chunk the entity is currently in, so use it
to more accurately unregister it in chunkCheck
Should maybe fix some entity loss issues.
Obscure detail in that if you teleport right on a chunk line, it
adds +1 to your collision check and will check the unloaded neighbor.
but the call to load the chunk then returned null if it was pending unload, such
as the load we did in Player List
However we want gen=true for players here anyways, so use getType
This also cleans up the implementation of Async Chunks to get rid of most
Consumer callbacks and instead return futures.
This lets us propogate errors correctly up the future chain
(barring one isn't lost even deeper in the chain...)
So exceptions can now bubble to plugins using getChunkAtAsync
While there is more down the collision system, remove some of the wrapping
Spliterator stuff as even this wrapper stream has shown up in profiling.
With other collision optimizations, we might also even avoid inner streams too.
This patch replaces the vanilla collision code for both block and entity collisions with faster implementations by JellySquid, used originally in her Lithium mod.
Optimizes Full Block voxel collisions, and removes streams from Entity collisions

Touched up by Aikar to keep previous paper optimizations
The collision code takes an AABB and generates a cuboid of checks rather
than a cylinder, so at high velocity this can generate a lot of chunk checks.
Treat an unloaded chunk as a collision for entities, and also for players if
the "prevent moving into unloaded chunks" setting is enabled.
If that setting is not enabled, collisions will be ignored for players, since
movement will load only the chunk the player enters anyways and avoids loading
massive amounts of surrounding chunks due to large AABB lookups.
Fixes#3321
This was using SIGNIFICANT amounts of memory allocating many
long[]'s for BitSets for every ProtoChunk in the cache that had
been unloaded and reloaded.
This will result in a nice memory reduction.
Actually showed up in profiling as decent time spent here...
Noticed y/z was missing its final that it use to have, when x had it. some how
must of got messed up on some update. though people suggest this shouldn't of
mattered anyways, but lets put it back for safety.
Added cache of hashcode, as well as optimized the hash code using larger primes.
Also stored the long value of the x/y/z so that for equals we can compare a single long,
as well as have that long value cached for .asLong()
This lets you run /paper fixlight <chunkRadius> (max 5) to automatically
fix all light data in the chunks.
Permission node is same "bukkit.command.paper"
Now tracks the full startup time for "Done" message at end, as apparently
Vanillas was done in a place that skipped tracking a lot of code too.
This fixes an issue with ViaVersion
Will now run those tasks just before we print "Done" so that startup
time is appropriately accounted for a plugin, as well as will no longer
trip the watchdog on startup.
Any plugin that tries to bypass this is just going to then trip watchdog
on Spigot too, so don't you dare.
Stop trying to cheat the delay your plugin added to startup time.
This isn't a behavior change because the first thing the tick does....
was run these tasks....
So it's just moving it slightly a few lines to be before a watchdog tick and
to account for it in "Done" time.
Fixes#3294
When adding/removing to a chunk, we need to also look at
editing the loaded entity list.

Removes synchronization from sending packets
Makes normal packet sends no longer need to be wrapped and queued like it use to work.
Adds more packet queue immunities on top of keep alive to let the following scenarios go out
without delay:
- Keep Alive
- Chat
- Kick
- All of the packets during the Player Joined World event
Hoping that latter one helps join timeout issues more too for slow connections.
Removes processing packet queue off of main thread
- for the few cases where it is allowed, order is not necessary nor
should it even be happening concurrently in first place (handshaking/login/status)
Ensures packets sent asynchronously are dispatched on main thread
This helps ensure safety for ProtocolLib as packet listeners
are commonly accessing world state. This will allow you to schedule
a packet to be sent async, but itll be dispatched sync for packet
listeners to process.
This should solve some deadlock risks
This may provide a decent performance improvement because thread synchronization incurs a cache reset
so by avoiding ever entering a synchronized block, we get to avoid that, and packet sending is a really
hot activity.
Undo the accidental renaming of a method in 0aad8bf
Aikar wanted to rename DataPalette#getDataBits(T object) to getOrCreateIdFor
in 0aad8bf but he also accidentally renamed
ChunkPacketInfo#getDataBitsIndex(int chunkSectionIndex) to
getOrCreateIdForIndex.
Remove chunk-edge-mode and chunk loading entirely from Anti-Xray
The chunk-edge-mode is broken since several versions.
Loading chunk neighbors for chunk edge obfuscation isn't needed anymore.
Unlike in previous versions, these are under normal circumstances already loaded
at the time we need them (plugins for example can bypass this).
Use the modified methods and constructors everywhere
Anti-Xray provides support for the default nms methods and constructors,
which where modified by Anti-Xray to avoid breaking stuff (plugins)
which somehow uses these methods.
However, the modified versions of those methods and constructors should be used
where possible.
