[dpdk-dev] [PATCHv2] headers: typeof -> __typeof__ to unbreak C++11 code

[Konstantin Ananyev <konstantin.ananyev@intel.com>]

v2:
Instead of changing all the affected files,
define 'typeofi' and 'asm' if needed.

When compiling C++11-code or above (--std=c++11), the build fails with
lots of

  rte_eth_ctrl.h:517:3: note: in expansion of macro RTE_ALIGN
    (RTE_ALIGN(RTE_ETH_FLOW_MAX, UINT32_BIT)/UINT32_BIT)
    ^

When reading the GCC info pages, I get the feeling that __typeof__ is
a better choice, and that indeed works when including the headers in
C++ files (--std=c++11).

There are some typeof()s left in C files, the patch only touches the
public API.
