compressor: add QAT support

This patch adds new QATzip plugin to support QAT for compression.

QATZip is a user space library which builds on top of the Intel
QAT (QuickAssist Technology) user space library, to provide extended
accelerated compression and decompression services by offloading the
actual compression and decompression request(s) to the hardware
QAT accelerators, which are more efficient in terms of cost and power
than general purpose CPUs for those specific compute-intensive
workloads.

Based on QAT accelerators, QATZip can support several compression
algorithm, including deflate, snappy, lz4, etc..
