Change the default DPDK version to 16.07, and rename the indicated
patch directory. Use the native vhost-user driver.

DPDK vhost-user support is disabled due to significan changes
in the DPDK vhost-user code which are not compatible with current
VPP code.

This change should improve DPDK performance on 40G+ NICs
with small packets.
It also removes ITR setting for i40e devices, allowing driver to set default.

The tarball repository fast.dpdk.org is fast and reliable enough
to be used in VPP build process.

* compiler -march= parameter is changed from native to corei7
so code is always genereted with instructions which are available
on the Nehalem microarchitecture (up to SSE4.2)
* compiler -mtune= parameter is added so code is optimized for
corei7-avx which equals to Sandy Bridge microarchitecture
* set of macros is added which allows run-time detection of available
cpu instructions (e.g. clib_cpu_supports_avx())
* set of macros is added which allows us to clone graph node funcitons
where cloned function is optmized for different microarchitecture
Those macros are using following attributes:
__attribute__((flatten))
__attribute__((target("arch=core-avx2)))
I.e. If applied to foo_node_fn() macro will generate cloned
functions foo_node_fn_avx2() and foo_node_fn_avx512() (future)
It will also generate function void * foo_node_fn_multiarch_select()
which detects available instruction set and returns pointer to the
best matching function clone.

For using clang as a compiler it is enough
to specify CC=clang in the make command line

DPDK 16.04 introduced new config parameter RTE_ARCH_X86
which was missing in the dpdk/Makefile
That caused issues with virtio devices on older kernels
(observed on 3.13.0).
This patch changes the source of generated config so
it will also include all defines in config/defconfig_TARGET
file.

poll mode driver library. The bonded interfaces to be created on
VPP startup is specified in the dpdk section of startup.conf
or qn.conf, using DPDK EAL command. Following is an example of a
dpdk section white listing PCI addressses of 4 ethernet interfacess
to be under VPP control plus two bonded interface and the PCI addresses
of the slaves in each:
dpdk { socket-mem 1024,1024
dev 0000:0f:00.0 dev 0000:10:00.0 dev 0000:11:00.0 dev 0000:12:00.0
vdev eth_bond0,mode=2,slave=0000:0f:00.0,slave=0000:11:00.0,xmit_policy=l34
vdev eth_bond1,mode=2,slave=0000:10:00.0,slave=0000:12:00.0,xmit_policy=l34
}
Note that only balance XOR (mode 2) is supported and "xmit_policy=l34"
specifies to use layer 3 SIP/DIP and layer 4 Sport/Dport for load
balance. Using "xmit_policy=l2" for SMAC/DMAC or "xmit_policy=l23" for
SMAC/DMAC and SIP/DIP should also work.
