b323fba934 vtenc: Avoid leaking caps object and its copy 
gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak. Also
the caps are pushed as an event downstream, but this doesn't consume the
caps so it must still be unreferenced.

dataPtr given to the CVPixelBufferCreateWithPlanarBytes

"plane description block" but no specific type is given.

e728ee8208 coremediabuffer: handle stride alignment 
Handle stride alignment through the use of the video meta API. The
code is based on the corevideobuffer implementation.

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.

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.
