Implement an h.264 decoder using Apple's VideoToolbox framework. Based on gstreamer's vtdec because there's very little documentation for this API beyond the framework's header file. Reuse the MOZ_APPLEMEDIA define from the mp3 decoder. AAC decoding is stubbed to use the BlankDecoderModule's 440A tone. Provide a stub header for the VideoToolbox framework and load it dynamically at run time so we can build and run on versions prior to MacOS X 10.8 where it's not available. Dynamically load the CoreMedia framework as well, but build against its headers since it's available on MacOS X 10.7 or later, which is our minimum build version.
