This patch adds a ffscale element to gst-ffmpeg. The element is based on
imgresample and can resize video. Right now there are other 2 similar elements
in gstreamer: videoscale and gdkpixbufscale, some things about these elements:

* ffscale is faster than gdkpixbufscale (a lot faster)
* ffscale is slower than videoscale* ffscale images are the same quality as
gdkpixbuscale's one
* videoscale has really bad quality (see #161079)
* ffscale supports only I420
* gdkpixbuscale supports only RGB

I'm attaching here for review.. and to see if someone other than me would like
to see this element in cvs :)
