Initial ODP-DPDK port

- Pulled necessary files from platform/linux-generic into
  platform/linux-dpdk
- Made necessary changes in files to get it compiled with dpdk library
	for eg.,
	* odp_buffer_hdr_t is mapped to struct rte_mbuf
	* All odp_buffer_* maps to rte_* in dpdk
	* necessary initialisations like odp_init_dpdk
	* All packet related changes in odp_packet.c and odp_packet_io.c
	* dpdk support in odp_packet_dpdk.c

- Add/modify files to support linux-dpdk compilation in new automake
  environment.
	* Modified configure.ac
	* Added platform/linux-dpdk/Makefile.am
	* Moved all files from platform/linux-dpdk/source to
	  platform/linux-dpdk/.

- Added platform/linux-dpdk/README on how to clone, compile DPDK and
  commands to execute on ODP.
- Made ODP_BUFFER_<TYPES> consistent with linux-generic.
- Removed odp_buffer_is_scatter API to be inline with linux-generic.
- Added platform/linux-dpdk/odp_linux.c to supply the function
  and argument to the pthread created by dpdk.
