Fix concurrency issues in DataFixers
We are seeing issues with DataFixers being not thread safe in async chunks
and even in some spigot packet sending code.

There are a few more global objects that are mutated that need to
be synchronized to be safe for use over multiple threads.

There may be more cases, but these are extremely obvious ones.

7cdfd6e538 [CI-SKIP] Improve last patch to not use wildcard
Since were having issues on windows for too many patch file names,
figured better use -R instead.

Also added $basedir back

ab56ada4d2 [CI-SKIP] Fix the NMS Imports detecting our own files
the way I handled this on my fork was using the metadata in the
git "stats" output of patches, however we don't include stats in
the patch files for paper so the code didn't work.

Changed the code to detect our own file editions inside of NMS
to a method that works without stats.

So we no longer need to manually add files to this list

Switch to using ForgeFlower for Paper Only mc-dev imports
ForgeFlower is better than Spigots FernFlower at decompiling the source.

However, in order to maintain the CraftBukkit patches, we must keep
using spigots for the primary.

However, for any file that we import on top of Spigots imported files
there is nothing stopping us from using better decompiled files.

So these changes will use ForgeFlower to maintain a better set of
decomped files, so anything we add on top of Paper can start off
in a better spot.

Configurable Alternative LootPool Luck Formula
Rewrites the Vanilla luck application formula so that luck can be
applied to items that do not have any quality defined.

See: https://luckformula.emc.gs for data and details
-----------

The rough summary is:
My goal was that in a pool, when luck was applied, the pool
rebalances so the percentages for bigger items is
lowered and smaller items is boosted.

Do this by boosting and then reducing the weight value,
so that larger numbers are penalized more than smaller numbers.
resulting in a larger reduction of entries for more common
items than the reduction on small weights,
giving smaller weights more of a chance

-----------

This work kind of obsoletes quality, but quality would be useful
for 2 items with same weight that you want luck to impact
in varying directions.

Fishing still falls into that as the weights are closer, so luck
will invalidate junk more.

This change will result in some major changes to fishing formulas.

-----------

I would love to see this change in Vanilla, so Mojang please pull :)

d45565f83b Handle gpg signing better (#1123)
Instead of checking whether it was set previously, setting it to false,
then setting it back to true if it was true before, just use the
command-line argument in git to override the config for that command.
Using a variable makes it pretty painless to do.

16869992a8 Call PaperServerListPingEvent for legacy pings (#1057)
* Make the legacy ping handler more reliable

The Minecraft server often fails to respond to old ("legacy") pings
from old Minecraft versions using the protocol used before the switch
to Netty in Minecraft 1.7.

Due to packet fragmentation[1], we might not have all needed bytes
available when the LegacyPingHandler is called. In this case, it will
run into an error, remove the handler and continue using the modern
protocol.

This is unlikely to happen for the first two revisions of the legacy
ping protocol (used in Minecraft 1.5.x and older) since the request
consists of only one or two bytes, but happens frequently for the
last/third revision introduced in Minecraft 1.6.

It has much larger, variable packet sizes due to the inclusion of
the virtual host (the hostname/port used to connect to the server).

The solution[2] is simple: If we find more than two matching bytes,
we buffer the remaining bytes until we have enough to fully read and
respond to the request.

Ability to apply mending to XP API
This allows plugins that give players the ability to apply the experience
points to the Item Mending formula, which will repair an item instead
of giving the player experience points.

Both an API To standalone mend, and apply mending logic to .giveExp has been added.

0f2c274998 Improve Structures Checking
Improves performance by keying every chunk thats part of a structure to a hashmap
instead of only the first one.

This allows us to avoid iterating the entire structures value set to see
if a block position is inside of a structure.

This should have pretty decent performance improvement to any standard world
that has been around for a whilewith lots of structures due to ineffeciencies
in how MC stores structures (even unloaded chunks has structured data loaded)

Add command for listing entities in a world
Port of 303a775fc3

Will display a list of all entities in a world, as well as which chunks
they are in. Hopefully, this will make tracking down chunks with lots of
entities easier.

Only real change from the forge version is that instead of dimension
IDs, we accept world names in the form of a string.

/paper entity list - Lists all entities in the player's current world
/paper entity list minecraft:zombie - Lists all zombies in the player's
current world

/paper entity list * world_nether - Lists all entities in the nether
/paper entity list minecraft:ghast world_nether - Lists all ghasts in
the nether

ec31ab32af Shame on you Mojang
Someone wrote some horrible code that throws a world accessing task
onto the HTTP DOWNLOADER Thread Pool, for an activity that is not even
heavy enough to warrant async operation.

This then triggers async chunk loads!

18433121dc Fix Old Sign Conversion
1) Sign loading code was trying to parse the JSON before the check for oldSign.
       That code could then skip the old sign converting code if it triggers a JSON parse exception.
    2) New Mojang Schematic system has Tile Entities in the new converted format, but missing the Bukkit.isConverted flag
       This causes Igloos and such to render broken signs. We fix this by ignoring sign conversion for Defined Structures
