[PATCH v4 0/7] Verify C++ compatibility of public headers

[Bruce Richardson]

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.

V4:
* add g++-multilib to packages to install for github checks to ensure 32-bit
  builds work
* correct the fixline for patch 1
* add extra cpp_args and cpp_link_args for 32-bit builds in test-meson-builds
  so that includes checks can pass there if enabled.

V3:
* update linux-build script to have cpp_args=-m32 for 32-bit builds

V2:
* Changed patch 6 to have a minimally-invasive fix for C++ without
  affecting existing C code.
* Added fixlines and Cc stable for all patches which are fixes
