Add new AF_XDP socket based packet IO implementation. Information about
AF_XDP and XDP can be found in [1].
ODP packet pool(s) created for packet IO entries are used as the UMEM
areas. Currently, only zero-copy mode is supported, copy-mode support
will be added later.
Depending on the XDP program loaded into the environment's NIC(s), TX
and RX queue selection for packets may differ. By default, only a single
combined queue is supported and this may require changing the
configuration of the NIC accordingly so that packets end up on the
AF_XDP socket created by ODP.

Rename implementation internal defines so that they stand out from the
API defines.

The config.h file has been split into three parts:
autoheader_build.h: should NOT be included by ANY source file
autoheader_external.h: can be included by any source file, including
public headers
autoheader_internal.h: can be included by any internal source file, but
NOT by public headers
autoheader_external.h and autoheader_internal.h are generated based on
matching template files (*.in) and include only ODP defines.
autoheader_build.h includes all build defines and should not be included
by any source file.
