This is the next step in supporting multiple DPDK PCI device/driver ABIs once those APIs are no longer public and subject to ABI versioning rules. This patch does the following: 1) introduce dpdk_fn_table 2) rename the existing dpdk_xx functions to xx_2207, to denote these functions are valid for DPDK versions up to and including 22.07 3) create a dpdk_fn_table pointing to the xx_2207 functions 4) create a global dpdk_fn_table pointer that points directly to the 2207 fn_table 5) create new dpdk_xx functions that just redirect to the associated dpdk_fn_table function pointer Future patches will add the machinery to register multiple function tables and pick the one to use at run time based on rte_version() calls.
