This resolves some issues which caused entities to not be resent correctly.
Entities that are interacted with need to be resent to the client, so we resend all the entity
data to the player whilst making sure not to clear dirty entries from the tracker. This makes
sure that values will be correctly updated to other players.
This also adds utilities to aid in further preventing entity desyncs.
This also also fixes the bug causing cancelling PlayerInteractEvent to cause items to continue
to be used despite being cancelled on the server.
For example, items being consumed but never finishing, shields being put up, etc.
The underlying issue of this is that the client modifies their synced data values,
and so we have to (forcibly) resend them in order for the client to reset their using item state.

Exposes the data component logic used by vanilla ItemStack to API
consumers as a version-specific API.
The types and methods introduced by this patch do not follow the general
API deprecation contracts and will be adapted to each new minecraft
release without backwards compatibility measures.

Fixes incorrect spigot handling of the invulnerability damage
reduction applied when an already invulnerable entity is damaged with a
larger damage amount than the initial damage.
Vanilla still damages entities even if invulnerable if the damage to be
applied is larger than the previous damage taken. In that case, vanilla
applies the difference between the previous damage taken and the
proposed damage.
Spigot's damage modifier API takes over the computation of damage
reducing effects, however spigot invokes this handling with the initial
damage before computing the difference to the previous damage amount.
This leads to the reduction values to generally be larger than expected,
as they are computed on the not-yet-reduced value.
Spigot applies these reductions after calling the EntityDamageEvent and
*then* subtracts the previous damage point, leading to the final damage
amount being smaller than expected.
This patch cannot simply call the EntityDamageEvent with the reduced
damage, as that would lead to EntityDamageEvent#getDamage() returning
the already reduced damage, which breaks its method contract.
Instead, this patch makes use of the DamageModifier API, implementing
the last-damage-reduction as a DamageModifier.
Anvils, by default, limit applied enchantment levels to their respective
maximum level. The added API enables plugins to disable this behaviour,
allowing enchantments that are overleveled to be applied via the anvil.
The CraftPlayerInventory implementation sends a container_set_slot
packet to the client which will error if an invalid slot is passed to
the setSlot method, making a validation necessary over simply silently
ignoring invalid slot values.
Horse inventories now combine 2 inventories (like
result inventories).

Exposes a new suspicious effect entry type that properly represents
storable effects in the context of suspicious effects as they only
define the potion effect type and duration.
This differentiates them from the existing PotionEffect API found in
bukkit and hence clarifies that storable values in the parts of the API
in which it replaces PotionEffect.
