Subject: [PATCH] Fix concurrenct access to lookups field in RegistryOps
The concurrent access occurs on the Netty IO threads when
serializing packets. Thus, it seems it was an oversight of
the implementator of this function as there are typically
more than one Netty IO thread.
Fixes https://github.com/PaperMC/Folia/issues/11

Subject: [PATCH] Optimise recalcBlockCounts() for empty sections
In 1.18, every chunk section is initialised to a non-null value
and recalcBlockCounts() is invoked for each section.
However, in a standard world, most sections are empty. In such cases,
recalcBlockCounts() would iterate over ever position - even though
the block data would all be air. To avoid this, we skip
searching the section unless the palette indicates there _could_ be
a non-air block state or non-empty fluid state.
Chunk loading initially showed that recalcBlockCounts() over
sections with a ZeroBitStorage data to to take ~20% of the process,
now it takes <1%.
