While it wasn't really "broken" before, if plugins use NMS
(which they really should't be) and mess with entity management
themselves, and get it wrong, they could ultimately corrupt our
state expectations.
I've been unable to reproduce any issues locally, but these changes
are the result of me analyzing the code pretty deeply and seeing
about how to make it more durable to abnormal usage.
Any servers seeing oddities, please run with -Ddebug.entities=true
and send me any logs triggered.
getting lots of bug reports on light. just going to drop this even though
I really don't see how it could be the source due to my understanding of
the games light engine...

Applied a "Only run this when the blocks are different" to
a place, that apparently must be called even with the same
block but different other data I guess.
This was causing oddness with light data.
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.
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.
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.
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.
