[PATCHv3 1/4] buildtools: Add tool to check EXPERIMENTAL api exports

[Neil Horman <nhorman@tuxdriver.com>]

This tools reads the given version map for a directory, and checks to
ensure that, for each symbol listed in the export list, the corresponding
definition is tagged as __experimental, erroring out if its not.  In this
way, we can ensure that the EXPERIMENTAL api is kept in sync with the tags
