The Bukkit#getRegistry(Class) method contract specifies that it returns
null for unknown registry types. The current implementation however
requires the passed class to be mappable to a known registry key.
For types like Material, which have a SimpleRegistry in bukkit's
Registry interface, no server side registry exists and such the type
cannot be mapped to a registry key.
The commit correctly returns null for types that are not mappable to a
registry key instead of throwing a NullPointerException.
Spigot still maintains some partial implementation of "tick skipping", a
practice in which the MinecraftServer.currentTick field is updated not
by an increment of one per actual tick, but instead set to
System.currentTimeMillis() / 50. This behaviour means that the tracked
tick may "skip" a tick value in case a previous tick took more than the
expected 50ms.
To compensate for this in important paths, spigot/craftbukkit
implements "wall-time". Instead of incrementing/decrementing ticks on
block entities/entities by one for each call to their tick() method,
they instead increment/decrement important values, like
an ItemEntity's age or pickupDelay, by the difference of
`currentTick - lastTick`, where `lastTick` is the value of
`currentTick` during the last tick() call.
These "fixes" however do not play nicely with minecraft's simulation
distance as entities/block entities implementing the above behaviour
would "catch up" their values when moving from a non-ticking chunk to a
ticking one as their `lastTick` value remains stuck on the last tick in
a ticking chunk and hence lead to a large "catch up" once ticked again.
Paper completely removes the "tick skipping" behaviour (See patch
"Further-improve-server-tick-loop"), making the above precautions
completely unnecessary, which also rids paper of the previous described
incompatibility with non-ticking chunks.
* Only mark decorations dirty if a removal actually occurs
Vanilla calls this method blindly inside of a loop which erroniously marks
map data files as being dirty even if nothing has actually changed.
* Merge into existing patch

In the recent upstream update, the paper player profile was updated to
correctly return null for both name and id if constructed as such. This
change however broke the serialisation logic, as it depended on the name
never being null.
The commit moves the checks over to the newly introduced emptyName/UUID
fields that track if the profile was constructed with a null name or
uuid to differentiate it against an empty string or the NIL_UUID.
Upstream has released updates that appear to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing

The updated velocity native compilation pipeline seems to emit binaries
that are not compatible with alpine.
The commit temporarily reverts the natives included until a proper
solution is found.
In the case where multiple messages from different players are being processed in parallel, there was a potential race condition where the messages would be sent to the client in a different order than the message signature cache was updated. However, the cache relies on the fact that the client and server get the exact same updates in the same order. This race condition would cause the caches to become corrupted, and any future message received by the client would fail to validate.
This also applies to the last seen state of the server, which becomes inconsistent in the same way as the message signature cache and would cause any messages sent to be rejected by the server too.
