    ipcpipeline: introduce new plugin for inter-process pipelines

    These elements allow splitting a pipeline across several processes,
    with communication done by the ipcpipelinesink and ipcpipelinesrc
    elements. The main use case is to split a playback pipeline into
    a process that runs networking, parser & demuxer and another process
    that runs the decoder & sink, for security reasons.
