1) Removed "Regen" mode of Dupe UUID resolver, forced safe.
Some servers who updated before we had safe mode added still had this value.
There's really no reason to keep this mode, as we've seen that vanilla
triggers this often and 99.9999999% of cases will be an actual duplicate
that needs to be deleted.
2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages
only show up if the debug.entities flag is on. This will stop server owners
from panicing from seeing these logs, and stop opening bug reports on this,
only for us to tell you "don't worry about it".
3) Avoid adding entities to world that are already added to world.
This can be triggered by anything that causes an entity to be added
to the world during the chunk load process, such as chunk conversions.
Issue #1544 was a case of this.
4) Removed debug warning about ExpiringMap.
Nothing more I know to do about this anyways. We recover from it,
stop warning to reduce noise of issues to us.
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
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.
Fixes#1506

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
light queue configurable.
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.
There is no reason for the light queue to even be an option. This
enables the light queue for everyone.
This also improves the "can we still tick" time logic to always
check before running a light operation.
previously, we always executed at least 10 on the first world
(but not other worlds...), but we are seeing light take up some
heavy time, so improving that for now.
I've now also improved recheck gaps logic to happen at the end of all single block updates
This also prevents multiple gap checks, as previously if a tick skipped
the gaps check, the next tick would end up re-adding the entry again,
resulting in multiple gap checks.
This now just sets a marker "We need to recheck gaps" and will only occur
once.
This also should reduce chunk loads, as previously, we checked if
the neighbor chunks were loaded for the gap check, however those
neighbor chunks might of unloaded before the light queue operation
actually ran. Now, the neighbor chunk is done when the gap check
is being done, so it should avoid loading chunks.

also ensure we never process already valid entities. this shouldnt be possible as of recent
commits as we made the entity slice array safer, but doesn't hurt for this logic to be safe too

Add "Safe Regen" Duplicate UUID resolver and make default
After witnessing behavior of the regeneration logs, its clear that Vanilla
has had bugs with saving duplicate entities for a while....
Some entities are saved in multiple chunks, and now we are bringing those duplicates
out that use to never surface.
This mode will analyze if the entity appears to be a duplicate (near the other dupe uuid)
and delete the entity instead.
This should reduce regenerations to entities that are nowhere near each other, and
therefore more likely to be subject to real UUID collisions due to our
previous bug, and therefor should survive the chunk load.
Vanilla logic checks unload queue and overwrites if its in it.
we're triggering this if a chunk unloads, and reloads immediately in same tick.
Added check for unload queue to not treat as duplicate
Also fixed the config setting not even loading
Should fix#1280
Citizens hijacks entity map, and im guessing under the right conditions
the result might actually be null during entity creation
Pre the cache patch, the id is looked up on save, so it was fine.
Now, if its null and the save ID is requested, we will try to look
it up again and cache it if found.

Add some debug for entity slices
Mark chunk dirty on entity changes

Due to a bug in bd75ff8b5b
which was added all the way back in March of 2016, it was unknown (potentially not at the time)
that an entity might actually change the seed of the random object.
At some point, EntitySquid did start setting the seed. Due to this shared random, this caused
every entity to use a Random object with a predictable seed.
This has caused entities to potentially generate with the same UUID....
Over the years, servers have had entities disappear, but no sign of trouble
because CraftBukkit removed the log lines indicating that something was wrong.
We have fixed the root issue causing duplicate UUID's, however we now have chunk
files full of entities that have the same UUID as another entity!
When these chunks load, the 2nd entity will not be added to the world correctly.
If that chunk loads in a different order in the future, then it will reverse and the
missing one is now the one added to the world and not the other. This results in very
inconsistent entity behavior.
This change allows you to recover any duplicate entity by generating a new UUID for it.
This also lets you delete them instead if you don't want to risk having new entities added to
the world that you previously did not see.
But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options.
It is recommended you regenerate the entities, as these were legit entities, and deserve your love.
