needed for the last 10 years. Far too much of the internal API is exposed, and every small adjustment causes applications to stop working. To kick this off, bump the API version to 0x17 as should have been done with r246713, but add shims to compensate. Thanks to the shims, there should be no visible change in application behavior. I have plans to do a significant overhaul of the API to harnen it for the future, but until then, I welcome others to add shims for older versions of the API. Obtained from: Netflix
