f3d8e3920d applemedia: only enqueue buffers in the VideoToolbox callbacks 
These callbacks may fire from any thread, hence we should only enqueue
buffers and let the streaming thread take care of the rest as soon as
the blocking encode or decode operation has finished.

f7e5878c9e applemedia: bring back Leopard compatibility 
At least as far as miovideosrc is concerned. Turns out that CoreVideo's
CVPixelBufferGetIOSurface is not present in Leopard's version of CoreVideo.
We solve this by making it possible for symbols to be marked as optional.

ec6c307334 qtkitvideosrc: run the mainRunLoop for a while if not running. 
QTCaptureSession::addInput and QTCaptureSession::addOutput call
NSObject::performSelectorOnMainThread internally so they need the mainRunLoop to
run at least for a while to complete.

abdb30c567 celvideosrc: fix nasty deadlock 
We cannot call any CMBufferQueue functions while holding the lock that
our callback also depends on. So now we make use of CMBufferQueue's
trigger API in order to get notified when the queue has data.

ebd2a6d6e9 applemedia: don't push synchronously from callback 
The codec that called us might be holding locks to shared resources, so
we should never push downstream from within its buffer callback.

Note that a GstBufferList is not used here because we need to preserve
the buffer metadata held by our GstBuffer subclasses.

invalidations of existing caches of the buffer contents.

c2672f71cd applemedia: improve vtenc/vtdec performance 
Profiling of H.264 encode and decode revealed that conversions
between packed and planar were happening behind the scenes.

Hence we now choose I420 instead of YUY2.
