Override some more methods in ExpiringMap to ensure fix
Seen some warnings of leak still being detected.

I'm not sure what's missing, so I'm adding nearly everything.

Fix major memory leaks in ExpiringMap
computeIfAbsent would leak as the entry
was never registered into the ttl map

This fixes that ,as well as redesigns cleaning to
not run on every manipulation, and instead to run clean
once per tick per expiring map.

Fix loop risk in mob spawning around unloaded chunks
When a mob was about to load a chunk to try to spawn in, we did not
increment the attempt counter, resulting in it being stuck in the mob
spawn loop for a long time and hanging servers.

Concurrency and Performance Improvements to DataFixers
Found some more unsafe operations in DataFixers.

Also replaced quite a few bad uses of Map.containsKey

containsKey is a common newbie mistake that "reads" cleaner, but
results in double the performance cost of all map operations as
containsKey in MOST cases where null values are not used is identical to get() == null

Considering how deep datafixers go in call stacks, with tons of map lookups,
this micro optimization could provide some gains.

Additionally, many of the containsKey/get/put style operations were
also a concurrency risk, resulting in multiple computation/insertions.

Ensure entity is always dying before Death Event
Prior to this it was possible for plugins to put the server into a never
ending recursive loop until it eventually killed itself.

Mob Pathfinding API

This does not do anything to stop other AI rules from changing the location, so
it is still up to the plugin to control that or override after another goal changed
the location.

BillyGalbreath c755f90933 Allow chests to be placed with NBT (#1425)
This restores vanilla behavior of allowing placed chests to retain any Block Entity Tag data.

Upstream added filtering to chests, breaking vanilla behavior, and preventing use of loot table chests as a reward mechanism.

Upon review, we can find no security risk in allowing players to place a chest with NBT data, as Spawn Eggs, Minecarts, command blocks etc all have their own checks.

Additionally, survival mode players, non op players can not create these items anyways. If a player has Creative or Op, they already have high levels of access.

Plus, Chests aren't the only inventory that could have free form items, so this filter was insufficient anyways.

Remove deadlock risk in firing async events
The PluginManager incorrectly used synchronization on firing any event
that was marked as synchronous.

This synchronized did not even protect any concurrency risk as
handlers were already thread safe in terms of mutations during event
dispatch.

The way it was used, has commonly led to deadlocks on the server,
which results in a hard crash.

This change removes the synchronize and adds some protection around enable/disable

Fix concurrency issues in DataFixers
We are seeing issues with DataFixers being not thread safe in async chunks
and even in some spigot packet sending code.

There are a few more global objects that are mutated that need to
be synchronized to be safe for use over multiple threads.

There may be more cases, but these are extremely obvious ones.

BillyGalbreath 997190c3e0 Add ray tracing methods to LivingEntity (#1410)
This method will return the Block a player is looking at while taking into consideration the AABB of each block in the path.

For example, you can look through the 1/4 space of air in a Stair block and get the block behind it instead of the Stair block you are looking past.

Gergely Sarkozi 2d45ec855f Cached, local-class-supporting task names (#1409)
Fixes issue #1177 

`MapMaker#weakKeys()` makes the `Map` use identity comparison for the keys, while also enabling the automatical removal of dropped classes from the cache.

The changes are the same as in #1399, except now the original patch is modified instead of a new one being created.
