loader: add support for gzip compressionAs we do have zlib code in loader, we should also support gzipcompression in zfs.PR: 153173Submitted by: Mikhail Zakharov Reviewed by: imp, markj, delphijDifferential Revision: https://reviews.freebsd.org/D35320MFC after: 1 month List of files: /src/sys/cddl/boot/zfs/README

MFV r245512: * Illumos zfs issue #3035 [1] LZ4 compression support in ZFS.LZ4 is a new high-speed BSD-licensed compression algorithm createdby Yann Collet that delivers very high compression and decompressionperformance compared to lzjb (>50% faster on compression, >80% fasteron decompression and around 3x faster on compression of incompressibledata), while giving better compression ratio [1].This version of LZ4 corresponds to upstream's [2] revision 85.Please note that for obvious reasons this is not backward readcompatible. This means once a pool have LZ4 compressed data, thesedata can no longer be read by older ZFS implementations.Local changes: - On-stack hash table disabled and using kernel slab allocator instead, at this time. This requires larger kernel thread stack for zio workers. This may change in the future should we adjusted the zio workers' thread stack size. - likely and unlikely will be undefined if they are already defined, this is required for i386 XEN build. - Removed De Bruijn sequence based __builtin_ctz family of builtins in favor of the latter. Both GCC and clang supports these builtins. - Changed the way the LZ4 code detects endianness. - Manual pages modifications to mention the feature based on Illumos counterpart. - Boot loader changes to make it support LZ4 decompression.[1] https://www.illumos.org/issues/3035[2] http://code.google.com/p/lz4/source/listObtained from: Illumos (13921:9d721847e469)Tested on: FreeBSD/amd64MFC after: 1 month List of files: /src/sys/cddl/boot/zfs/README
