Add checks during build to ensure that all symbols in the EXPERIMENTAL version map section have __experimental tags on their definitions, and enable the warnings needed to announce their use. Also add an ALLOW_EXPERIMENTAL_APIS define to allow individual libraries and files to declare the acceptability of experimental api usage Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Acked-by: Thomas Monjalon <thomas@monjalon.net>
