97d59045ae [BLEEDING][BREAKING][INSTABLE] Swiftly throw in permission caching.
Benefits:
* Improves performance, where permission lookup has major impact, with
timeout based lookup, static permissions (skip permission check
entirely), and world/offline based invalidation. (Once fully
implemented.)
* Hopefully more efficient: use Bukkit Permission for faster defaults.
* (Allows control over how which permission is to be
updated/invalidated, which is useful per se.)

Risks:
* Complex changes yield bugs.
* Other plugins depending on NCP might break.
* Cache incoherence might happen (permissions are changed dynamically +-
unintended malconfiguration, or in case of bugs).
* (Endless loops certainly have all been fixed.)

Breaking:
* Lots of more or less internal API has been changed or removed: Check,
CheckType, CheckUtils, TickTask, ...
* Permission checking behavior has been altered.

Rough points:
* Implement a permission cache within PlayerData.
* Remove the player tasks and permission updates in favour of handling
those within DataManager and PlayerData.
* Adjust everything else to it (partly TBD).
* Updating sets of permissions (e.g. for CHAT) is done more lazily now,
i.e. one per 10 ticks). An actual permission check would still yield an
update next tick (asynchronous).
* Fixed/extended random spots (DualCollection, MiniListener registration
support, StringUtil).

Missing:
* Basic implementation
  * Cleanup after logout (stages: 1. non-essential like permissions,
2. unrecoverable like set-back location, 3. complete data removal).
* Coverage
  * Might have missed spots.
  * NoCheatPlus.nameSetPerms should be replaced by caching + default
config for world-wise updating.
  * Command permissions are always checked. At least for players,
cache based lookup should get implemented.
  * More unit tests.
* Extended configurability: Per-world settings/policies.
* Efficiency
  * Not all parts of the implementation are 100%/optimal yet.

863b89763d [BREAKING] Move more classes around.
This time the focus is on the utilities package.

Possibly used, but not really official API:
* Move block cache to a 'map' sub-package.
* Move RichBounds/RichEntity/Player-Location and TrigUtil to a location
sub-package.

Not really official API, likely not used:
* Move AttribUtil to compat, since it belongs there.
* Split off direction check methods to collision.CollisionUtil.
* Move static BlockCache methods to map.MapUtil.
* Move food related methods from CheckUtils to InventoryUtil.
* Move vehicle/passenger related methods from CheckUtils to
PassengerUtil.

Not breaking:
* Move IdUtil to commons.

2bf3e14ab9 More on GenericInstanceRegistry.
* Add a way to stay updated about the latest registration state for a

* Add a class for the registry.
* Let the registry log all registrations.
* Make super interfaces for LogManager (simple logging of
String/Throwable).

Missing:
* More streams (REGISTRY, PLAYER/CHECK_STATUS/EVENTS or just CHECKS at
least). Make status rather the plugin status. Registry could have an
extra file.
* More efficient IGenericInstanceHandle use (wrap + reference counting).

554c8635e7 Sketch a reflection based provider for IEntityAccessLastPositionAndLook.
Directly following:
* Boat fly check based on VehicleUpdateEvent and fetching last pos.
* Implement a native access based provider for
EntityAccessLastPositionAndLook, after testing the reflection based one.

Likely following:
* Implement the same fly checks based on PlayerMoveEvent for horses and
pigs too, for the case server-side fly checking is disabled.
* Configurability for individual types of enbtities, at least a flag for
activation.
* Not sure if a fall-back to VehicleMoveEvent should be kept, setup
shouldn't be all too complicated.

Untested, unused. Intentions are:
* Be able to count any use of workarounds.
* Confine workarounds to side conditions, such as 'use once until
conditions are reset' and/or 'only use once conditions are set'.
* Have per-player objects and (attached) global counters.
* (Might think of: disable workarounds by configuration.)

4d59f67d34 Switch the default asynchronous CallContext to ASYNCHRONOUS_TASK.
This will preserve the order of debug messages sent from multiple
threads. As a side effect, this might be better for performance, given
that on constant input the logging task will stay registered, so there
is little overhead and the file-io is taken off the asynchronous packet
and chat handler threads.Hopefully the thread switching is less
expensive than the gain by not delaying chat/packet threads, in case of
servers with few cores. We might adapt the used policy later, based on
cores and/or config.

08c5aa2d7c Implement a linked coord hash map, custom order, tests.
Can't implement "dumb" access order, because we will have to move
entries to the front with setting and altering data, but we don't want
the data to be changed every time get is called, e.g. with piston
tracking.

Efficiency could be increased, using the entry as reference instead of
duplicate calls with coordinates.
