f6154b4cc0 applemedia: always fill GstBuffers with GstMemory
Always fill buffers with our custom memory. The custom memory will avoid
mapping CV/CM buffers unless necessary.

b6747292e0 qtkitvideosrc: get the framerate from caps
...and configure QTKit accordingly. Hardcoding to 30fps was pretty -bad.

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.

86e2539816 qtkitvideosrc: implement zero-copy by using buffer-factory
This means we'll wrap each CoreVideo buffer inside a GstBuffer instead of
making a copy.

3a44d4c1f9 qtkitvideosrc: fix up refcounting
Should keep a strong reference to the device, but we don't need to manage
the reference count of elements of an NSMutableArray as it takes care of
that for us.

b39609b405 qtkitvideosrc: simplify timestamping algorithm
Aligning timestamps on duration boundaries, skipping frames and so forth
are clearly things that fall outside the scope of a video source.

0e4e351b83 applemedia: New plugin for Apple multimedia APIs
Provides the following elements:

qtkitvideosrc: OS X video source relying on the QTKit API. Comes with
hard-coded caps as the API does not provide any way of querying for
formats supported by the hardware. Hasn't been tested a lot, but seems
to work.

miovideosrc: OS X video source which uses the undocumented/private
CoreMediaIOServices API, which is also the one used by iChat.
Present on latest version of Leopard and all versions of Snow Leopard.
Has been tested extensively with built-in cameras and TANDBERG's
PrecisionHD USB camera.

vtenc, vtdec: Generic codec wrappers which make use of the undocumented/
private VideoToolbox API on OS X and iOS. List of codecs are currently
hard-coded to H.264 for vtenc, and H.264 + JPEG for vtdec. Can easily be
expanded by adding new entries to the lists, but haven't yet had time to
do that. Should probably also implement probing as available codecs depend
on the OS and its version, and there doesn't seem to be any way to
enumerate the available codecs.

vth264decbin, vth264encbin: Wrapper bins to make it easier to use
vtdec_h264/vtenc_h264 in live scenarios.

iphonecamerasrc: iPhone camera source relying on the undocumented/private
Celestial API. Tested on iOS 3.1 running on an iPhone 3GS. Stops working
after a few minutes, presumably because of a resource leak. Needs some
love.

Note that the iOS parts haven't yet been ported to iOS 4.x.
