Updates the dpdk build system to support the lastest DPDK libraries v1.5 and above
This drops support for anything before v1.5 due to the requirment to patch the build system.
Hopefully this new way will continue to work with newer releases
This removes the need to patch the DPDK library
Instead the only requirement is that DPDK is built as a static library with the following options
CONFIG_RTE_BUILD_COMBINE_LIBS=y EXTRA_CFLAGS="-fPIC added to the make command
-This line, and those below, will be ignored--
M configure.in
D Intel DPDK Patches/DPDKLibtracePatch.patch
M Intel DPDK Patches/README
M lib/format_dpdk.c
A lib/dpdk_libtrace.mk
