Refactor API message handling code
This is preparation for new C API. Moving common stuff to separate headers reduces dependency issues. Change-Id: Ie7adb23398de72448e5eba6c1c1da4e1bc678725 Signed-off-by: Klement Sekera <ksekera@cisco.com> (cherry picked from commit 58eb866b15a45514dc356170f28640d6c9db8034)
