[PATCH v4 0/5] Initial compressdev unit tests

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

Added initial tests for Compressdev library.
The tests are performed compressing a test buffer (or multiple test buffers) with
compressdev or Zlib, and decompressing it/them with the other library (if compression is
done with compressdev, decompression is done with Zlib, and viceversa).

Tests added so far are based on the deflate algorithm,
including:
- Fixed huffman on single buffer
- Dynamic huffman on single buffer
- Multi compression level test on single buffer
- Multi buffer
- Multi xform using the same buffer

Due to a dependency on Zlib, the test is not enabled by default.
Once the library is installed, the configuration option CONFIG_RTE_COMPRESSDEV_TEST must be set to Y.
However, if building with Meson, the test will be built automatically, if Zlib is installed.

The test requires a compressdev PMD to be initialized, when running the test app. For example:

./build/app/test --vdev="compress_X"

This patchset depends on the Compressdev API patchset:
http://dpdk.org/ml/archives/dev/2018-April/099580.html
("[PATCH v6 00/14] Implement compression API")

Changes in v4:
- Free memory when malloc fails

Changes in v3:
- Remove next pointer in xform setting
- Remove unneeded DIV_CEIL macro
- Add rte_compressdev_close() call after finishing test cases

Changes in v2:
- Add meson build
- Add invalid configuration tests
- Use new Compressdev API:
  * Substitute session with priv xform
  * Check if priv xform is shareable and create one per operation if not

Pablo de Lara (5):
  test/compress: add initial unit tests
  test/compress: add multi op test
  test/compress: add multi level test
  test/compress: add multi xform test
  test/compress: add invalid configuration tests
