Add option to disable relative projectile velocity Allows server owners to use 1.8 (and prior)'s projectile behavior (ignored shooter's velocity when calculating projectile's velocity). This patch adds an option "disable relative projectile velocity", which, when enabled, will cause projectiles to ignore the shooter's current velocity, like they did in Minecraft 1.8 and prior. If a player is falling, for example, their shooting range will be drastically reduced, as a downwards velocity is applied to the projectile. This prevents players from saving themselves from falling off floating islands, for example, as a thrown ender pearl will not make it back to the island, while it would have in 1.8. While this could easily be done with plugins, too, there are multiple problems: 1) If multiple plugins cancel the velocity by subtracting the shooter's velocity from the projectile's velocity, the projectile's velocity would be different. As there's no way to detect whether the projectile's velocity has already been adjusted to ignore the player's velocity, plugins can't not do it if it's not necessary. 2) I've noticed some inconsistencies, e.g. weird velocity when shooting while using an elytra. Checking for those inconsistencies is possible, but not as efficient as just not applying the velocity in the first place. 3) Solutions for 1) and especially 2) might not be future-proof, while this server-internal fix makes this change future-proof.

Subject: [PATCH] Configurable projectile relative velocity
This patch adds an option "disable relative projectile velocity", which, when
nabled, will cause projectiles to ignore the shooter's current velocity,
like they did in Minecraft 1.8 and prior.
If a player is falling, for example, their shooting range will be drastically
reduced, as a downwards velocity is applied to the projectile. This prevents
players from saving themselves from falling off floating islands, for example,
as a thrown ender pearl will not make it back to the island, while it would
have in 1.8.
While this could easily be done with plugins, too, there are multiple problems:
P1) If multiple plugins cancel the velocity by subtracting the shooter's velocity
from the projectile's velocity, the projectile's velocity would be different.
As there's no way to detect whether the projectile's velocity has already been
adjusted to ignore the player's velocity, plugins can't not do it if it's not
necessary.
P2) I've noticed some inconsistencies, e.g. weird velocity when shooting while
using an elytra. Checking for those inconsistencies is possible, but not as
efficient as just not applying the velocity in the first place.
P3) Solutions for 1) and especially 2) might not be future-proof, while this
server-internal fix makes this change future-proof.

Anti Xray cleanup Undo the accidental renaming of a method in 0aad8bf Aikar wanted to rename DataPalette#getDataBits(T object) to getOrCreateIdFor in 0aad8bf but he also accidentally renamed ChunkPacketInfo#getDataBitsIndex(int chunkSectionIndex) to getOrCreateIdForIndex. Remove chunk-edge-mode and chunk loading entirely from Anti-Xray The chunk-edge-mode is broken since several versions. Loading chunk neighbors for chunk edge obfuscation isn't needed anymore. Unlike in previous versions, these are under normal circumstances already loaded at the time we need them (plugins for example can bypass this). Use the modified methods and constructors everywhere Anti-Xray provides support for the default nms methods and constructors, which where modified by Anti-Xray to avoid breaking stuff (plugins) which somehow uses these methods. However, the modified versions of those methods and constructors should be used where possible.
