It was conflicting with vhost examples because of new logtype:
	http://dpdk.org/browse/dpdk/commit/?id=7b79b2718f0d028cc0

I've ported fragmentation and reassembly ports to the new ip_frag library
instead of the duplicated code from the old example.

I've removed CONFIG_RTE_TEST_PIPELINE option. CONFIG_RTE_LIBRTE_PIPELINE
should be sufficient.
By the way, more build options conditioning could be needed in order to
disable some features (e.g. disabling LPM lib should silently skip LPM port).

Commit splitting have been reworked for atomicity, especially makefiles and
doxygen files.

Packet Framework is a big piece of code which is now applied to master branch
and should be ready for version 1.7.0.

Thanks a lot
