5c4d65efb8 Require plugins to be explicitly marked as Folia supported
Plugins must add "folia-supported: true" to their plugin.yml
otherwise the server will refuse to load them.

Since Folia is a major breakage for plugins, the vast majority
of plugins will not function correctly on Folia. To prevent
user confusion from this, we will refuse to load the plugin
and provide a log indicating why - which will be much
more helpful than some random error log caused by
a breakage.

4e7205d401 Change entity scheduler API to use Runnables
The generics pose a problem, and the parameter passed to the
Consumer is not needed in API.

Additionally, stop trying to cancel Bukkit scheduler tasks on
plugin disable as the Bukkit scheduler does not work.

04b28a65ca Fix mob spawning
We should only iterate over the local region's entities, not the
global entity list to set up the spawner state, as everything else
about the spawner state (player count / chunk count) is regionised.
Additionally, move the last spawner state to regionised state so that
paper mobcaps command functions as expected.

bb3f8a4aea Process player chunk loader mid tick at the start of tick
Additionally, process ticket updates as well if either
the mid tick logic did anything or whether we processed
any chunk tasks.

We process the mid tick logic at the start to be consistent
with the inbetween task execution logic (which is not implemented),
and we process ticket updates to ensure that any full status changes
are processed from chunk tasks.

093b1e5394 Fix several issues, mostly saving pending teleporting entities
The place/portal async function now track entities that have been
removed from the world but have not teleported. When the server
shuts down, these entities will have their passenger tree restored
and re-added to the entity slices at the location they were teleporting to,
or in the case of portals that did not run placeAsync yet,
the location they entered the portal on. This should ensure that
for regular teleports that the entity is placed at its correct
target location, and for portalling to ensure that either
the entity is placed at the portal entrace location (where
they entered) or the portal destination. In any case,
the entity is preserved in a location and will survive
the shutdown.

Additionally, move player saving until after the worlds save. This
is to ensure that the save logic is performed only after
all teleportations have completed.

Fix some other misc issues as well:
 - Fix double nether portal creation by checking if a portal exists again
   before creating it, fixing a race condition where two entites would portal
   and neither would see that the other created a portal.
 - Make all remove ticket add an unknown ticket.
   In general this behavior is better since it means that unloads will only
   ever occur at the next tick, rather than during the tick logic. Thus,
   there will be no cases where a chunk is unloaded unexpectedly.
 - Do not use fastFloor for calculating chunk position from block position
   It is not going to return a good value outside of [-1024, 1024]
 - Always perform mid tick update for ticking regionised player chunk loader
   If no entities were loaded, no chunks were loaded, and nothing else -
   the logic would not have otherwise ran. This fixed some rare cases of
   chunks never loading for players after logging in.

30d90b4700 Make raids thread-safe
We don't need to worry about synchronisation for saving data,
as that is currently only done by the shutdown thread - after
all regions stop ticking.

5a4351d3b6 Improve thread-safety of combat tracker
The simple solution is that we ignore entities/positions that are not
in the current region. Making retrieval of items in inventory
thread-safe is not going to happen.

b772012778 Make the StructureCheck class MT-Safe
This is so that it may be accessed concurrently
from many regions.

Additionally, make sure it does not leak memory by limiting
the number of entries it will cache.

6d922d4b48 Implement player sleep status / night skip
Now, all of the sleep status changes are pushed to the global
tick thread. Had to modify the wake up all players routine
to use the task scheduler to ensure the player is woken up
on the right region context.

Fix erroring while crashing on the global tick thread due to
region field being null.

Now, the spawning should be running Vanilla logic; except
that it is calculated per region (which is what per player

fd7901d0f1 Implement TPA system for test server
Will be removed later once this is all public.

Fixed many issues with teleporting players on vehicles
while in the same region.

Additionaly, make sure dead players are dismounted - as
this logic was previously done by remove.
