    v4l2sink: implement gstvideosink.show_frame instead of gstbasesink.render

    It allows to show preroll frame. Especially it allows to update the
    frame when seeking in PAUSED state.

    v4l2bufferpool: Copy already queued buffer

    This is required as during preroll we pass the first buffer twice, hence
already
    queued. It is also useful, to allow filters replaying a previous rendered
buffers.
    This will require 1 more buffer in sink if last-sample is enabled, since
the last
    sample will not be the same as the currently queued buffer.
