This patch series add software zlib library (http://zlib.net/)
based compression PMD in DPDK compress drivers.

Application must need to install zlib prior to enabling
this PMD to avail compression/decompression services.
Currently driver only tested for deflate, stateless
compression and decompression.

Changes in v3:
- added comp_feature_flags to compressdev_capabilities
- removed stream_create as stateful not supported
- changed compression strategy to DEFAULT_STRATEGY
- Simplified core processing logic
- fix doc build error
- other v2 feedbacks

TBDs
- No change to current qp enqueue_err stats update.
- PMD increment enqd_err stats, if it fails to push op
  into completion queue. This logic to be revisited based on
  further discussion

Changes in v2:
- removed unused variables
- corrected capability to reflect current support
- add lookup for internally maintained mempool during device_configure
- optimized core compression/decompression logic in enq/deq APIs
- updated documentation with correct feature support

v1 includes:
- build changes to build zlib PMD
- zlib PMD implementation
- zlib PMD documentation
- meson build support

This patchset is dependent upon compressdev API.
