    decodebin: Analyze source pad before setting to PAUSED for 'simple
demuxers'

    Before we were setting them to PAUSED and (much) later connecting to
    their source pad caps notify signal.

    There was a race where that demuxer was pushing a caps and later a buffer
    on its source pad when we were not even connected to its source pad caps
notify
    signal leading to decodebin missing the information and not keeping on
    building the pipeline on CAPS event thus the demuxer was posting an ERROR
    (not linked) message on the bus. This need to be done for 'simple
    demuxers' because those have one ALWAYS source pad, not like usual demuxers
    that have several dynamic source pads.

    A "simple demuxer" is a demuxer that has one and only one ALWAYS source
    pad.
