This commit adds support for the creation of tap devices.
To create a tap device, and associate it with a DPDK port,
add within the port section:
vdev=<tap_name>
local ipv4=<ip_assigned_to_port>
<tap_name> will appear as a kernel network device, with an IP <ip_assigned_to_port>
ARP packets received from the network on the DPDK interface will be forwarded to the kernel.
1st packet which needs to be generated to a new IP will cause an IP packet
to be sent to the kernel (using socket sendto) forcing the kernel to send an ARP_REQUEST.
In this commit, there is no notification from the kernel about ARP table changes.
This is subject to further commits.
Two config files, gen_tap.cfg and swap_tap.cfg have been created. They work one against each other.
*** Note however that they do not work if running within the same host
(with the port being connected back to back) ***
This is due to the fact that the kernel would bypass the ports and use local interface...

This commit prepares PROX for supporting changes from DPDK 19.08
Mainly, the "sed" listed below were run.
In addition,
- some forward definition have been removed,
- prox_compat.h has been updated
- prox_compat.h has been included where necessary.
Hence such a commit is rather easy to review and to reapply
on other branches if necessary.

mbuf size was setup to achieve the best performance i.e.
using the smallest mbuf and not segmenting packets.
However this resulted in complex code, much dependent of the way
the pmd are working e.g. a change(fix) in recent dpdk i40e
implementation caused a 1782 (=1518+8+256) bytes mbuf to be too
small to hold a 1518 bytes packets.
Hence this change simplifies the mbuf size selection at the price
of a potential decreases in performance - as more memory is now used.
Except if jumbo frames are used, the mbuf size will now be the same
for all modes. The packets will not be segmented except if jumbo
frames are enabled.
If jumbo frames are enabled, packets are by default segmented, except
if the mbuf size is configured big enough in the config file.

Add support for pkt_inline of jumbo frames.
Dump the whole packet, and not a truncated packet. This might
have a small impact on performance as the memory footprint
is increased (by ~640K * number of tasks), resulting in potential
higher DTLB misses.

JIRA: SAMPLEVNF-55
PROX is a DPDK-based application implementing Telco use-cases such as
a simplified BRAS/BNG, light-weight AFTR... It also allows configuring
finer grained network functions like QoS, Routing, load-balancing...
(We are moving PROX version v039 to sampleVNF
