Also rename the relevant API so we mirror the public API more closely, and switch to CoreFoundation CFTypeRef style typedefs. We still support the old private CoreMedia in order to not break OS X support. This means that vtenc and vtdec are now compatible with iOS 4.x, and in theory also future versions of OS X, where this API may turn public like it has on iOS.
