The lock in DataWatcher is used to prevent concurrent modifications
to the 'd' field (entries in MCP). However any modifications to
this map only occur on initialization of an Entity in its
constructor. This modification is write-locked.
Every other access is through a readlock, which allows
the threads to pass if there is no thread holding the
writelock.
Since the writelock is only obtained in the constructor
of the Entity, the further readlocks are actually
useless (which get obtained on set, get, etc calls).
The entries field ('d' currently) has also been declared as
Int2ObjectOpenHashMap to avoid autoboxing on put(), get(), etc
calls.
Testing in game verified the zombie's arms raise and fall correctly
when using the API.
Renamed the OBFHELPER since the method is placed on EntityInsentient
(since we want to conflict on changes).
Note: The entity parameter stays 'this' since we want the block the
entity is targetting. This can change based on the block the player
has in their hand (see scaffholding). With a scaffhold in hand, the
scaffhold blocks in the world become solid 1x1x1 cubes, and without they
follow their model's shape.
- Add missing isCancelled check
We don't need to worry about going out of range of int
since the value is clamped to view distance, and view
distance is clamped to 33

CraftBukkit Changes:
7d29eb5e SPIGOT-4899: Horse inventory title not set
Tux pointed out the patch still has O(n^2) time complexity since
the sublist class in arraylist does not override clear() from
AbstractList, which uses a forward moving iterator to clear
the list.
Resolved by using a peek and poll from ArrayDeque.
This patch also removes the useless WeakHashMap which holds
the list (it mapped world->list) and replaces it with a
field on World.

- Re-removes Bukkit#getServerName - This was (hopefully?) only added back
for Timings v2. It should be kept in that scope.
- Intend to let PlayerViewDistance API slip. Given the scope of the
changes in this area it seems best to let this slip past initial
release. It can be re-added when there is additional time to focus on it
and the changed systems it relies on. If it is fixed prior to release
this is implemented as a single shim patch that can be dropped.
