Use GstPoll to wait for the fd of the video device to become readable before
trying to capture a frame. This speeds up stopping v4l2src a lot as it no
longer has to wait for the next frame, especially when capturing with low
framerates or when the video device just never generates a frame (which seems a
common issue for uvcvideo devices)
Fixes bug #563574.
sort_by_frame_size is declared static and only used inside
an ifdef, so use the same ifdef to define the function. Fixes#572185

Remove non-embedded mode. Embed mode becomes default and only mode.
embed property is retained for binary compatibility.
Added autorelease pools around all objc functions that might be called
from a non-main thread.
Ensure we create the ringbuffer segment size as a multiple of the
bytes per sample (fixes 6-channel output).
Reset the segoffset when acquiring the ringbuffer, so we don't retain
a bogus offset when caps change.

(gst_v4l2src_probe_caps_for_format_and_size), (sort_by_frame_size),
(gst_v4l2src_probe_caps_for_format):
Turns out we don't always get the frame sizes in a predefined
order from lowest to highest resolution, so let's just sort the
list by frame size once we've queried the possible resolutions
rather than assume any particular order. Fixes probed caps for
the camera in my HP2133 mini notebook and makes v4l2src default
to a decent size.

Rewrite caps setting and ring buffer initialisation.
Previously we never told CoreAudio what format we were going to send it,
so it only worked due to luck, and not at all on some hardware.
Now we explicitly advertise what formats the hardware supports, and then
configure the selected one correctly.
