[PATCH v5 0/5] crypto: improve asym session usage

[Ciara Power <ciara.power@intel.com>]

This patchset includes improvements for the asymmetric session.
The main change is to the session structure, which is now a single
mempool object, rather than having pointers to private data elsewhere.
This session structure is now hidden in an internal header,
so the app will never use it directly.

Some other changes include adding a user data API, and modifying
the return value for the create session function.
This create session function now also initialises the session,
and subsequently the clear/free functions have been merged into one.

Sample code in the programmer's guide that showed basic steps for
using Asymmetric crypto in DPDK has been replaced with literal includes
in the first patch of this patchset. This ensures all subsequent code
changes in the patchset are automatically reflected in the documentation.

v5:
  - Modified which patch the sess parameter is passed to session create
    trace function.
  - Reworded create session function description.
  - Removed get API for session private data, can be accessed directly.
  - Modified test application to create a session mempool for
    TEST_NUM_SESSIONS rather than TEST_NUM_SESSIONS * 2.

v4:
  - Added new patch to add literal includes usage in programmer's guide.
  - Merged asym crypto session clear and free functions.
  - Reordered some function parameters.
  - Updated trace function for asym crypto session create.
  - Fixed cnxk clear, the PMD no longer needs to put private data
    back into a mempool.
  - Renamed struct field for max private session size.
  - Replaced __extension__ with RTE_STD_C11.
  - Moved some parameter validity checks to before functional code.
  - Reworded release note.
  - Removed mempool parameter from session configure function.
  - Removed docs code additions, these are included due to patch 1
    changing sample doc to use literal includes.
  - Initialised session variables as NULL.
  - Added possible error return values in user data API comment.

v3:
  - Added documentation in relevant patches.
  - Fixed setting user data size.
  - Fixed hiding structure, it should not be hidden from PMDs.
  - Fixed some other small formatting issues.
  - Increased size of max_priv_session_sz to uint16_t.
  - Removed trace for asym session init function that was
    previously removed.
