Subject: [PATCH] Make sure inlined getChunkAt has inlined logic for loaded
chunks
Tux did some profiling some time ago and showed that the
previous getChunkAt method which had inlined logic for loaded
chunks did get inlined, but the standard CPS.getChunkAt
method was not inlined.
Paper recently reverted this optimisation, so it's been reintroduced
here.

packet-limiter:

limits:
all:
interval: 7.0
max-packet-rate: 500.0
PacketPlayInAutoRecipe:
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

Subject: [PATCH] Consolidate flush calls for entity tracker packets
Most server packets seem to be sent from here, so try to avoid
expensive flush calls from them.
This change was motivated due to local testing:
- My server spawn has 130 cows in it (for testing a prev. patch)
- Try to let 200 players join spawn
Without this change, I could only get 20 players on before they
all started timing out due to the load put on the Netty I/O threads.
With this change I could get all 200 on at 0ms ping.
(one of the primary issues is that my CPU is kinda trash, and having
4 extra threads at 100% is just too much for it).
So in general this patch should reduce Netty I/O thread load.

Subject: [PATCH] Allow removal/addition of entities to entity ticklist during
tick
It really doesn't make any sense that we would iterate over removed
entities during tick. Sure - tick entity checks removed, but
does it check if the entity is in an entity ticking chunk?
No it doesn't. So, allowing removal while iteration
ENSURES only entities MARKED TO TICK are ticked.

Subject: [PATCH] Optimise random block ticking
Massive performance improvement for random block ticking.
The performance increase comes from the fact that the vast
majority of attempted block ticks (~95% in my testing) fail
because the randomly selected block is not tickable.
Now only tickable blocks are targeted, however this means that
the maximum number of block ticks occurs per chunk. However,
not all chunks are going to be targeted. The percent chance
of a chunk being targeted is based on how many tickable blocks
are in the chunk.
This means that while block ticks are spread out less, the
total number of blocks ticked per world tick remains the same.
Therefore, the chance of a random tickable block being ticked
remains the same.
