wli5 6a9d635998 GZIP compression offloading with QAT accelerator
This patch implement the hardware accelerator method in GZIP compression
in ZFS. When the ZFS pool is enabled GZIP compression, the compression
API will be automatically transferred to the hardware accelerator to
free up CPU resource and speed up the compression time.

* To enable Intel QAT hardware acceleration in ZOL you need to have QAT
  hardware and the driver installed:
  * QAT hardware DH8950:
  http://ark.intel.com/products/79483/Intel-QuickAssist-Adapter-8950
  * QAT driver:
  https://01.org/intel-quickassist-technology
* Start QAT driver in your system:
  service qat_service start
* Enable QAT in ZFS, e.g.:
  ./configure --with-qat=<qat-driver-path>/QAT1.6
  make
* Set GZIP compression in ZFS dataset:
  zfs set compression = gzip <dataset>
* Get QAT hardware statistics by:
  cat /proc/spl/kstat/zfs/qat
* To disable QAT in ZFS:
  insmod zfs.ko zfs_qat_disable=1
