This commit doesn't do much on its own, but adds a new Java Cleaner API that lets us hook into Garbage Collector events to reclaim pooled objects and return them to the pool. Adds framework for Network Packets to know when a packet has finished dispatching to get an idea when a packet is done sending to players. Rewrites PooledObjects impl to properly respect max pool size and remove almost all risk of contention. Bumps the Paper Async Task Queue to use 2 threads, and properly shuts it down on shutdown.

Subject: [PATCH] Optimize UserCache / Thread Safe
|
|
|
|
Because Techable keeps complaining about how this isn't thread safe,
|
|
easier to do this than replace the entire thing.
|
|
|
|
Additionally, move Saving of the User cache to be done async, incase
|
|
the user never changed the default setting for Spigot's save on stop only.
