[PATCH 0/7] Verify C++ compatibility of public headers

[Bruce Richardson <bruce.richardson@intel.com>]

This patchset expands upon the exiting chkincs infrastructure to build a
C++ test application as well as the existing C test app, which helps
catch any build errors when the public DPDK headers are included in C++
code. The rest of this patchset fixes the errors caught by this
additional check - mostly missing casts, but also one use of "new" as a
variable name, and one missing closing brace for an 'extern "C"' block.

NOTE: the most complicated changes are in the 6th patch, where there
were linux headers included which were not C++ compatible. This patch
moves the inclusion of those headers to non-public locations in the code
to remove those issues, but I am uncertain what the knock-on impacts of
this change may be. Therefore, I ask particular review from vhost/vdpa
maintainers to see if there is a better solution to this issue

Bruce Richardson (7):
  eal: fix header build with C++
  eventdev: fix header build with C++
  graph: add explicit cast to allow C++ build
  ipsec: : add explicit cast to allow C++ build
  table: add explicit casts for C++ compatibility
  vhost: remove non-C++ compatible includes
  buildtools/chkincs: test headers for C++ compatibility
