[v5,0/7] Add new cryptodev op for event metadata

  For using event crypto metadata, event metadata need to be set
in session. For this session user data was used for symmetric
crypto sessions and no support was present for asymmetric and
security sessions.
The use of userdata to store event metadata (which is dereferenced
in PMD) is not correct as it is meant for the application to use it.
Hence, a new API is created to set and get event crypto metadata which
is scalable to all sessions supported by the crypto PMD.
The application can use the set API to set event metadata and the
PMD may store that inside the session private data and PMD need not
use the get API as it would be internal to the PMD.
For the software event crypto adapter implementation, the eventdev
library can use the get API to get the event metadata stored inside
the session structure.
For Asymmetric sessions, a new field is added inside the session
struct which is internal to library.
For symmetric and security sessions, new field cannot be added as
it would be ABI break. Hence, session userdata is being used to
store that as it was used earlier. In next ABI break release this
would be fixed similar to asymmetric crypto case.

The patchset also add support for asymmetric crypto adapter
in the test applications and the crypto/cnxk implementation of
the new cryptodev op and corresponding changes in the eventdev lib.

changes in v5:
removed extra check for freeing mdata

Changes in v4:
- added null checks in set API
- updated check in session destroy
- updated API comments
- fixed test app failure reported by Abhinandan.
- moved event mdata after padding in asym session struct.

Changes in v3:
- fix SW adapter case of memory allocation/free of mdata. mdata is
allocated in set API and freed in session clear/destroy.
- mark rte_cryptodev_session_event_mdata_get as internal API
as it is only needed for the app or the PMD.

changes in v2:
- v1 patchset only fixed security sessions and also caused ABI breakage.
This is fixed in v2.
- added new API for setting event metadata.
- added new cryptodev op which can handle all sessions


Akhil Goyal (5):
  crypto/octeontx: use new API for event metadata
  test/event: use new API to set event crypto metadata
  eventdev: use new API to get event crypto metadata
  test/event: add asymmetric cases for crypto adapter
  test-eventdev: support asym ops for crypto adapter

Volodymyr Fialko (2):
  cryptodev: add APIs to get/set event metadata
  crypto/cnxk: add event metadata set operation
