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.

ideally this should of never mattered, as it will only
be hit if you teleport out of an unloaded chunk...
But apparently some people are triggering this.
See #1223
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.
Spigot had code that returned early in chunk add/remove methods.
This was causing our code added to set current chunks and counts to
be skipped over if the entity was default not persistent but made persistent.
This was the source of many issues
Fixes#1208
This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.
We also store counts by type to further enable other performance optimizations in later patches.
Instead of overriding add within the queue, never add runnables to the
queue if the light queue is disabled.
This change is made to make timings reports and stacktraces less
confusing for administrators, who prior to this change, would have seen
the lighting queue referenced in both, regardless of whether or not it
was enabled.
This change should not affect performance, nor is it made with the
intent to.
may help #284
Cleans up the lighting queue system, reducing diff and improving implementation.
We no longer stop chunk unloads due to lighting updates, and instead simply flush the lighting queue.
The cost of forcing the chunk (and its neighbors!) to stay loaded waiting for its
lighting work to finish is much greater than simply taking the hit and doing the work.
This change also helps reduce the diff and avoid bugs with missed diffs by removing
duplicated logic.
Also switches to a more effecient data structure (ArrayDeque instead of LinkedList) for the queue itself.
The lighting queue spreads out the processing of light updates across
multiple ticks based on how much free time the server has left at the end
of the tick.
