1st full patch GstDisparity

"This element computes a disparity map from two stereo images, meaning each one
coming from a different camera, both looking at the same scene and relatively
close to each other - more on this below. The disparity map is a proxy of the
depth of a scene as seen from the camera."

This element has an interesting twist: same as videomeasure, it is a muxer that
normally needs to wait until both frames are present on its input pads before
carrying out the stereo mapping. This is, strongly inspired by videomeasure,
achieved via a mutex + condition variable + a buffer being NULL or not.
