1) Get rid of string interning. can be heavy, has been seen to cause issues for some users
2) Use ConcurrentHashMap instead of a SynchronizedMap
3) Stop use of MRUMapCache which is not thread safe for Group lookups
4) Stop using IdentityHashMap which has performance issues in Java 8
In Java 11 the internal reflection method used to determine the calling
class in the legacy and deprecated Timings API, that no one should be
using anymore, was removed.
This means plugins that try and use it will all fail to enable and we
can't compile the server with JDK 11.
The solution to the removal of this internal reflection class is
to just use reflection to call it if its available and fall back to
the unnamed handler system if it isnt.
Update to the newer API if you use Timings already...
Upstream has released updates that appears to apply and compile correctly.

With 1.13, the idea of accessing chunks async is going to have to
be supported with the push towards thread safe chunk access mojang
has done.
This commit changes timings to always thread check at start and stop
timings and only mutate state on main thread.
This makes startTimingIfSync pointless, but I'm just going to leave
it as is.
Timings will no longer complain when used async, it just will not
do anything.
Further concurrency issues have been addressed with creating
timings handlers that may of overall been an issue for any handler
that might of been created async (happened even for things that
only timed sync)
with that, the 'protected' concept of handlers has been removed,
and 'plugin' vs 'safe' handlers are now the same.
Got rid of some guava functions in favor of java 8 real stuff now too.

I have tested that the Replenishing Feature still works as expected.
Lootable API's that now have Bukkit equivalents are now deprecated.

2b0e71c7 Rebuild patches
This branch/commit is only useful to those who purely use a clean Bukkit/Spigot/Paper API
and does not use NMS/OBC references.
This will let you start updating your plugin to the latest 1.13 builds of Bukkit Preview (4 as of now)
Note that this release is not final!!! API breakages may occur!
It is up to you if you find use out of this work.
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.
Fixes our own, and upstream's, issues with the stricter Java 8 JavaDoc
linter.
Also removes the destroystokyo-release maven repository. I'm not sure
why I added it originally, but it's unnecessary now.
Finally made timings accept "Callback style" reports, so plugins
can listen for when the report is done.
Added new Util interfaces, MessageCommandSender and BufferedCommandSender
This restores and improves using RCON to generate timings reports
I believe we are getting data corruption by doing it in the middle of the tick, as I was seeing
really odd reports from automated ones vs command ones.
This will break issueing timings over rcon single command mode and getting the report link in the response back
But I will try to restore that (and make RCON no longer cause spikes) soon.
Reports will still generate, just because its async, the RCON connection
will drop if not in terminal mode before its done.
Require user to confirm the timings reset, warning them that they should not be doing this.
Also require Timings to have ran for 3 minutes before allowing the report command.
Also require 1 minute intervals between reports to stop report spam.
