Jake Potrebic 29d059d659 Fix sticky pistons and BlockPistonRetractEvent
There is an explicit check in the handling code for empty pistons that
prevents sticky pistons from firing the event. However when we look back
at the history we see that this check was originally added so that ONLY
sticky pistons would fire the retract event. I'm not sure why.
https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/1092acbddf07edfa4100bc6824504ac75088e913

Over the course of several updates, the meaning of that field appears to
have changed from "is NOT sticky" to "is sticky". So now its having the
opposite effect. Only normal pistons fire the retraction event. And like
all things in CB, it's just been carried around since.

If we are to believe the history, the correct fix for this issue is to
flip it so it only fires for sticky pistons, but that puts us in a
bind. It's already firing for non-sticky pistons, changing it now would
likely result in breakage. Furthermore, there is little documentation as
to WHY that was ever intended to be the case.

Instead we opt to remove the check entirely so that the event fires for
all piston types.

stonar96 71ac6d7e6a Optimize HashMapPalette
HashMapPalette uses an instance of CrudeIncrementalIntIdentityHashBiMap
internally. A Palette has a preset maximum size = 1 << bits.
CrudeIncrementalIntIdentityHashBiMap has an initial size but is
automatically resized. The CrudeIncrementalIntIdentityHashBiMap is created
with the maximum size in the constructor of HashMapPalette, with the aim
that it doesn't need to be resized anymore. However, there are two things
that I think Mojang hasn't considered here:
1) The CrudeIncrementalIntIdentityHashBiMap is resized, when its initial
size is reached and not the next time, when a further object is added.
2) HashMapPalette adds objects (unnecessarily) before checking if the
initial size of CrudeIncrementalIntIdentityHashBiMap is reached.
This means to actually avoid resize operations in
CrudeIncrementalIntIdentityHashBiMap, one has to add 2 to the initial size
or add 1 and check the size before adding objects. This commit implements
the second approach. Note that this isn't only an optimization but also
makes async reads of Palettes fail-safe. An async read while the
CrudeIncrementalIntIdentityHashBiMap is resized is fatal and can even lead
to corrupted data. This is also something that Anti-Xray is currently
relying on.

egg82 61353ac496 Add root/admin user detection
This patch detects whether or not the server is currently executing as a privileged user and spits out a warning.
The warning serves as a sort-of PSA for newer server admins who don't understand the risks of running as root.
We've seen plenty of bad/malicious plugins hit markets, and there's been a few close-calls with exploits in the past.
Hopefully this helps mitigate some potential damage to servers, even if it is just a warning.

Jake Potrebic e259cfeb72 Fix upstreams block state factories
Sometimes, blocks are changed and then logic is called before the associated
tile entity is removed. When this happens, the factories were relying on the
block at the position, not the tile entity. This change prioritizes using the
tile entity type to determine the block state factory and falls back on
the material type of the block at that location.

lexikiq 5c4d5afef1 Preserve overstacked loot
Preserves overstacked items in loot tables, such as shulker box drops, to prevent the items
from being deleted (as they'd overflow past the bounds of the container)-- or worse, causing
chunk bans via the large amount of NBT created by unstacking the items.

Fixes GH-5140 and GH-4748.

Spottedleaf 0277ecd75d Add packet limiter config
Example config:
packet-limiter:
  kick-message: '&cSent too many packets'
  limits:
    all:
      interval: 7.0
      max-packet-rate: 500.0
    ServerboundPlaceRecipePacket:
      interval: 4.0
      max-packet-rate: 5.0
      action: DROP

all section refers to all incoming packets, the action for all is
hard coded to KICK.

For specific limits, the section name is the class's name,
and an action can be defined: DROP or KICK

If interval or rate are less-than 0, the limit is ignored

Spottedleaf 12321d761e Don't lookup fluid state when raytracing, skip air blocks
Just use the iblockdata already retrieved, removes a getType call.

Also save approx. 5% for the raytrace call, as most (expensive)
raytracing tends to go through air and returning early is an
easy win. The remaining problems with this function
are mostly with the block getting itself.

Async catch modifications to critical entity state
  These used to be here from Spigot, but were dropped with 1.17.
  Now in 1.17, this state is _even more_ critical than it was before,
  so these must exist to catch stupid plugins.
