[dpdk-dev] [PATCH v4 2/4] regexdev: add regex core h file

[Ori Kam <orika@mellanox.com>]

This commit introduce the rte_regexdev_core.h file.
This file holds internal structures and API that are used by
the regexdev.

Signed-off-by: Ori Kam <orika@mellanox.com>
Acked-by: Guy Kaneti <guyk@marvell.com>
---
v4:
* No changes.

v3:
* Align internal function pointers API to the RTE level API.
 
v2:
* Move private data to rte_regexdev struct.
