AOO: #i124800# switch avmedia's QuickTime component to QTKit for now

because the QuickTime API is not available to 64bit clients. The switch to QTKit
is temporary only because it has already been deprecated in OSX 10.9. We'll have
to switch to OSX's AVFoundation framework instead soon.

AOO: #i124875# support Mac AV-Foundation API for multimedia content

Adapted as needed and gbuildified by tml. For the files that actually
are Objective-C++ use the .mm suffix.

AOO: #i124875# avoid wasteful loading of an AVAsset in MacAVF::Framegrabber

FrameGrabber used to load its own copy of a movie. Since multimedia content
is often very data-intensive this should and can be avoided by using the
movie asset already available in the Player.
