Previously TreeMap was used which has poor get(K) performance.

Numerous fixes to entity related changes
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.

Why are plugins accessing this?! Whhhhy?!

For any plugin developers reading this, this are methods in World
specifically for adding entities to the world, aptly called spawnEntity

Make region files more reliable to write to
Previously we would write to header before writing our chunk data,
which opens a window for corruption (or we would overwrite entirely).
Now the saving process has been changed to follow this chain of events:

1. We always allocate a new space to write so we do not potentially
overwrite and corrupt the current data
2. Write the chunk data first (the order of the fields in
the chunk data isn't relevant though)
3. Flush to disk
4. Write to the region header last
5. Flush to disk
6. Then we free the previous space allocated

With this chain of events it is impossible for a chunk write to corrupt
a region file, unless the operating system has lied and we have NOT flushed
to disk.

However server administrators are still recommended to continue performing
regular backups.

Note that when Mojang finally decides to change their region format
to deal with oversized chunks this patch must be changed to deal with
whatever system they decide to impose.

We also make use of two flushes to disk per chunk save (to ensure
ordering and ensure data has gone to disk), so this will negatively
affect save performance.

Allow login events to fire only after the server has loaded
Plugins that rely on the async login event to fire can miss the event
if a player tries to log in before the server has loaded.

The solution is to simply block the event threads from executing until
the server has loaded. This will not have an adverse affect on logins
since the event threads are cached and are only used for executing events
asynchronously.

Improve upstream merge script to rebuild patches
this will help ensure that upstreams apply as cleanly as it does manually

the filtering makes the patches more fragile, but usually not an issue for small updates.

this will unfilter, apply the cleanest patches, then the next rebuild will
filter out unnecessary changes

761d6ae72e Fix PersistentStructureLegacy NPE on custom worlds

Restore vanilla behavior of mob counts for persistent mobs
Now decounts entities that got name tagged or persistent state changed.

Removes a bad CB check that ignored some persistent mobs persistence state.

Vanilla code explicitly only cares 'is this mob persistent?' and if
it is, it is not counted. CB should not of been checking its type state.

Optimize Persistent Data Loading
removes Mineshaft loading legacy as we had pre 1.13.2 to avoid managing
that very large data file from legacy systems.

Previous to 1.13.2 these data files were never loaded to begin with, so they
effectively do not contain valid/relevant data.

These files take a long time to convert on large worlds and crashes the server.

Additionally, cache the result of a file being missing so we don't keep spam checking it.

Reuse buffers for chunk compression to optimize memory use
Instead of allocating a buffer for every chunk compression, reuse
the same 64k sized buffer.

Also stopped doing dynamic compression levels. It wasn't helping enough.

This will improve memory usage and zlib performance of chunk compression.

PlayerDeathEvent#getItemsToKeep
Exposes a mutable array on items a player should keep on death.

This allows a cleaner method to implement "Keep certain items on death"
than how plugins currently do it in that it never removes them in first
place, so its safe if the player logs out/server is shutdown before respawn.

Example Usage: https://gist.github.com/aikar/5bb202de6057a051a950ce1f29feb0b4

8e9ec4b058 Don't update entity trackers for worlds without players
PlayerList#moveToWorld already untracks the player from the player list,
meaning that we do not need to worry about this untracking players
who've left the world, The server also untracks a player during
disconnect, handing yet another case.

If we don't need to untrack players who've left the world, it should be
reasonably save to do this, as we're not going to be performing any
server->client updates here, which is what this code is intended to do,
and all players should be untracked.

Restore some SANITY around nullability annotations
Some of these were wrong (scoreboard manager), others are counter to
everything everyone expects (Locations world being null, which wasnt ever safe EVER)
others are just too noisy.

Replace some with Contract to get rid of the nullability constraint and go back to
the old days of IDE not considering it strictly one way or the other.

Also, stop requiring annotations on package-private.

Introduces the next Developer Perk for Paper-API: Your plugin isn't yellow anymore.

Also fixed random dupe code in ensureServerConversions that got mistakenly set in the update.

Add a config for mob spawn change, really shouldn't use it
turning this to true allows 1 player to deny other players the ability
to have mobs spawn. It really is a bad idea and reverts back to iffy
mob spawn limits where mob farms in the world stops natural spawns
from occuring.

Really recommend resorting to different solutions than ever using this config.
