v4l2src: optional support for device probing with gudev

This new patch just adds support for device probing using gudev.
Now that the device is opened in READY state there is no more need for udev
based property getters so that part has been stripped out.

Now the workflow for device probing would be:
probe devices with propertyprobe
for (devices) {
  set "device"
  set GST_STATE_READY (open the device)
  get useful properties (e.g. drop non capture devices)
  set GST_STATE_NULL (close the device)
}

Note that this patch is *a lot* more trivial than the previous.
If this would be applied cheese will have a little regression because there
won't be any way to retrieve Product and Vendor id for the devices. Another
patch that adds those properties to v4l2src will probably follow.
