Andrew Purtell 2e4d9a2adf HBASE-27019 Minor compression performance improvements (#4420)
TRACE level logging is expensive enough to warrant removal. They were
useful during development but are now just overhead.

Also we unnecessarily create new compressor and decompressor instances
in the reset() methods for the Aircompressor and Lz4 codecs. Remove.

Andrew Purtell b6bb18022f HBASE-26316 Per-table or per-CF compression codec setting overrides (#3730)
We get and retain Compressor instances in HFileBlockDefaultEncodingContext,
and could in theory call Compressor#reinit when setting up the context,
to update compression parameters like level and buffer size, but we do
not plumb through the CompoundConfiguration from the Store into the
encoding context. As a consequence we can only update codec parameters
globally in system site conf files.

Fine grained configurability is important for algorithms like ZStandard
(ZSTD), which offers more than 20 compression levels, where at level 1
it is almost as fast as LZ4, and where at higher levels it utilizes
computationally expensive techniques to rival LZMA at compression ratio
but trades off significantly for reduced compresson throughput. The ZSTD
level that should be set for a given column family or table will vary by
use case.

Andrew Purtell 18b9fa8a3c HBASE-26259 Fallback support to pure Java compression (#3691)
This change introduces provided compression codecs to HBase as
new Maven modules. Each module provides compression codec support
that formerly required Hadoop native codecs, which in turn relies
on native code integration, which may or may not be available on
a given hardware platform or in an operational environment. We
now provide codecs in the HBase distribution for users whom for
whatever reason cannot or do not wish to deploy the Hadoop native
codecs.
