[v3,0/7] ethdev: add flow API object converter

  This is a follow up to the "Flow API helpers enhancements" series submitted
almost a year ago [1]. The new title is due to the reduced scope of this
version.

rte_flow_conv() is a flexible replacement to rte_flow_copy(), itself a
temporary solution pending something better [2]. It replaces a lot of
duplicated code found in testpmd and removes some of the maintenance burden
that developers tend to forget (me included) when modifying pattern
items or actions (updating app/test-pmd/config.c to be clear).

This series was unearthed in order to complete the implementation of
RTE_FLOW_ACTION_TYPE_ENCAP_(VXLAN|NVGRE) in testpmd [3] without having to
duplicate existing code once again.

See individual patches for specific changes in this version.

v3 changes:

- Marked rte_flow_conv() as experimental, modified net/bonding accordingly.
- Fixed compilation issue on ARM.
- Removed deprecation notice.

v2 changes:

- rte_flow_copy() is kept, albeit deprecated, no API/ABI impact.
- Updated bonding PMD.
- No more automatic generation of rte_flow_conv.h.

[3] Currently the command-line parser (cmdline_flow.c) is aware of these
    actions, however config.c isn't. Flow rules with such actions cannot
    be created and cannot be validated with PMDs that implement them.

No more comment after one month.
Ferruh, I think it should go into next-net.

Series applied to dpdk-next-net/master, thanks.
