George Melikov 522f2629c8 zio_compress: introduce max size threshold ... Now default compression is lz4, which can stop compression process by itself on incompressible data. If there are additional size checks - we will only make our compressratio worse. New usable compression thresholds are: - less than BPE_PAYLOAD_SIZE (embedded_data feature); - at least one saved sector. Old 12.5% threshold is left to minimize affect on existing user expectations of CPU utilization. If data wasn't compressed - it will be saved as ZIO_COMPRESS_OFF, so if we really need to recompress data without ashift info and check anything - we can just compress it with zero threshold. So, we don't need a new feature flag here!
