    MiniObject: Make it an opaque refcounted class generated by gmmproc.
    
        * gstreamer/gstreamermm/filelist.am:
        * gstreamer/gstreamermm/miniobject.{cc,h}:
        * gstreamer/gstreamermm/private/miniobject_p.h: Remove these files and
        remove them from the build.
        * gstreamer/gstreamermm/private/.gitignore: Also update the .gitignore
        file.
    
        * gstreamer/src/filelist.am:
        * gstreamer/src/miniobject.{ccg,hg}: Add these new files wrapping
        GstMiniObject and include the files in the build.
        * gstreamer/src/enums.hg (MiniObjectFlags): Move enum to the
        miniobject.hg file.
        * tools/m4/convert_gst.m4: Update the conversions file to include
        needed conversions.
