BillyGalbreath a16ef75bfd Add sun related API (#1546)
These methods are used internally throughout the game for things like spawning mobs during day/night only or making them burn in daylight, etc. Now exposed for plugin usage.

Fix rebuildPatches and grep colors not reverting junk changes
we've seen some index lines change in length in some PR's, though
this script was suppose to ignore those changes already.

The only way I can see that not working is if the color mode
of grep is breaking the pattern matching, as some people
default their grep to use color=always

this adds color=none to ensure colors are disabled, should ensure it.

Improvements to Async Chunks
If a chunk load comes in on a chunk load or gen thread,
execute it synchronously on that thread instead of enqueueing it.

It doesn't make sense to enqueue it as that thread is then
going to future.join() it and block until it's ready anyways.

This opens risk to a deadlock if every load or gen thread is
waiting on a recursive chunk but it will never finish because
all of the threads are waiting.

Identify corrupt region file data and self recover
If we identify an invalid offset (negative, or the header sectors),
then back up the region file and erase that specific chunks offset
data.

This will avoid crashing the server with AIOBB errors and also avoids
server owners having to consider the entire region file 'lost'.

I'm not sure what leads to this state, I can only assume write cut
off mid bits.

In this scenario, there is absolutely no way to know where the chunk
actually is in the data file without loading every
single chunk in the file. And even to do that, would be quite extreme
due to the fact the file isn't in some orderly fashion.

Since the file is backed up, the user can use a region fixer tool
externally to try to restore that single chunk. We could even
add a command to restore a chunk from a backup file in a different
commit later on. But this at least prevents the server from crashing.

The server will just generate a new chunk and move on,
after printing an error to the console about it.

Also fixed the case reported in this issue about the server
hanging when a corrupt chunk is encountered, so this issue
is now fully closed.

Fix Light Bugs - Fixes #1542
Applied a "Only run this when the blocks are different" to
a place, that apparently must be called even with the same
block but different other data I guess.

This was causing oddness with light data.

Improve synchronization on chunk gen to not block main - Fixes #1550
Chunk Generation was occuring while inside of the progressCache lock
this caused the progressCache to stay blocked for a long period of time
which then blocked main when main needed to clean the expiring map.

We now maintain a separate map for pending scheduler entries, that
we can join on if a 2nd request comes in while one is starting.

This strategy keeps the lock only for a fraction of time but
maintains thread safety.

So now the chunk is generated without holding a lock and wont
block the main thread on the expiring map as we will insert it
once ready.

Improvements to Logging Warnings/Dupe Entities - Resolves #1544
1) Removed "Regen" mode of Dupe UUID resolver, forced safe.
Some servers who updated before we had safe mode added still had this value.

There's really no reason to keep this mode, as we've seen that vanilla
triggers this often and 99.9999999% of cases will be an actual duplicate
that needs to be deleted.

2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages
only show up if the debug.entities flag is on. This will stop server owners
from panicing from seeing these logs, and stop opening bug reports on this,
only for us to tell you "don't worry about it".

3) Avoid adding entities to world that are already added to world.

This can be triggered by anything that causes an entity to be added
to the world during the chunk load process, such as chunk conversions.

Issue #1544 was a case of this.

4) Removed debug warning about ExpiringMap.

Nothing more I know to do about this anyways. We recover from it,
stop warning to reduce noise of issues to us.

MaterialTags API
This adds a plethora of useful Tags to let you identify common grouping
of materials. This should complete all of the categories that mojang
did not provide official tags for plus some more.

These are not "registered" tags. They are not usable in any form of
command system that might support tags.

These are provided as a Paper maintained list of items so that plugins
do not have to worry about maintaining all these tags themselves.

This API can technically be copy and pasted into a plugin, and plugins
can add additional Tags's if they wish too to their plugin by
instantiating a MaterialSetTag.

Fix lag caused by water mobs across the board - Fixes #1462
This update introduces Entity Activation Range for water mobs.

Activation Range has been one of my biggest performance improvements
I ever added to Minecraft, however "Entity is in Water" is an immunity
case that keeps an entity active.

This update ignores the water check for known water based mobs, allowing
them to actually go inactive.

In addition to that, a new config option was added to spigot.yml to go with
the rest of the entity-activation-range options to let you configure
aquatic mobs like fish, squid and dolphins separately.

This should overall fix all lag caused by water mobs.

[CI-SKIP] Remove Trove and update to fastutul 8 on -api
These deps were marked as provided, not compile, so they were never
exposed to plugins anyways as we THOUGHT we had done, oops.

Well plugins can still add fastutil to their build and use the
deps as provided by minecraft.

This ensures -api side does not use a deprecated API as fastutil 8
removed the deprecated methods.

Add config options to paper.yml for Async Chunks and Shared Host Overrides
Shared Hosts have been concerned over the increased CPU usage that Async Chunks
has introduced. We understand that shared hosts can't allow 1 client
to abuse the systme resources depriving other servers of cpu time, so we've
added some configs to allow hosts to force some settings.

Hosts, you may set the following SYSTEM ENVIRONMENT VARIABLES (NOT JVM FLAGS)
to change some behavior:

PAPER_ASYNC_CHUNKS_SHARED_HOST_GEN=1   - Enable Single Threaded World Generation (capping CPU Usage
PAPER_ASYNC_CHUNKS_SHARED_HOST_GEN=2   - Disable Async Chunk Generation - Please do not do this!!!
  - Minecraft is moving towards asynchronousm per-world chunk generation itself. You need to prepare
  - for this, so please do not disable async chunk generation.

PAPER_ASYNC_CHUNKS_SHARED_HOST_LOAD=#  - Where # is Maximum number of threads to use on Chunk Loading
  - This is a max, so your end user can reduce it more too. I suggest no lower than 2. Minimum is 1.
  - These are usually much faster request, so outside of loading entire worlds, They usually do not
  - get as much load. Paperby default uses CPU Core count * 1.5, so this may default to a higher value
  - on shared host and you should override it with this value to say 2-4.

These settings will override your clients paper.yml options. Set as a system wide environment
variable to ensure all Paper clients respect your resource usage desires.

Disable use of Locks on main thread for DataPaletteBlock
This should greatly improve performance by using a No Op lock
while on the main thread.

Vanilla always had a write lock on write operations, but we added
a Read Lock during Async Chunks to make concurrent writes non fatal
for Async Chunks.

This means we added on a bunch of over head to all chunk read operations.

This corrects that, as well as disabling the write lock while on main thread.

It is a general rule that you do not touch a chunk async once it is loaded
into the world, as we never had locks on the chunk before 1.13 even.

So once we are on main, we don't expect concurrent access to begin with,
so we don't need the write locks either.

Optimize some light chunk access
light calculations repeatedly looks up the same chunk while going
down on the Y access. Pass the chunk to it to skip many round trips
to the map lookup process.

while the gains arent as big since we have last access cache, it
should hopefully avoid many callstacks of depth and improve inlining,
as well as avoids entering a synchronized code block.

The avoiding of entering synchronized section is the main goal here.

Many times I've ran paper test trying to SHUTDOWN
the existing test server, only for it to see that my target folder

Well, the patch process will wipe out any uncommitted changes, causing
loss of work.
