Here's some related patches for review - adding a couple of new SKIP flags, and
implementing the video SKIP flags in the gst-libav video decoder. Starting with
the decoders is the simplest place, and already helps a lot on the CPU,
although obviously not on the disk reads.

On top of this would be handling the flags in the demuxers to reduce the data
read/pushed out where possible, and to implement the skipping in the audio
decoders (and push gap events so things still preroll).
