    playbin2: Minor cleanup of decoder-sink compatibility checking code

    playbin2: Make sure that the decoders we plug are compatible with the fixed
sink

    The fact that a decoder is not compatible with the fixed sink
    is currently happenning in the case where we have hardware accelerated
    video decoders on the system (especially vaapi elements that are actually
plugged),
    and the user is providing a sink that doesn't support the surface.

    A simple example that shows how it used to crash on a system where
gstreamer-vaapi
    is installed:
        gst-launch playbin2 video-sink=xvimagesink
uri=/codec/supported/by/vaapi

    What we are now doing in this case, is avoid using the accelerated
    decoder and plug a "normal" decoder instead (if avalaible).

    This commit doesn't handle the case where we have hardware accelerated
    demuxing.
