Get ready to have multiple implementations of the
dpdk_fn_table. We could do some fancy self-registering
constructor functions, but let's just keep it simple
for now and extern declare each implementation in
the pci_dpdk.h header file.

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.
