Minecrell 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.

* Add legacy ping support to PaperServerListPingEvent

Add a new method to StatusClient check if the client is a legacy
client that does not support all of the features provided in the
event.

Fix Dragon Server Crashes
If the dragon tries to find "ground" and hits a hole, or off edge,
it will infinitely keep looking for non air and eventually crash.

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.

Aikar 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

Aikar 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!

What in the hell were you thinking?

Aikar 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
