    dmabuf: share the mapping with shared copies of the memory

    With lots of shared memory instances (e.g. created by a RTP payloader) the
    overhead of duplicating the file descriptor and creating extra mappings is
    significant. To avoid this, the parent memory maps the whole region and the
    shared copies just reuse the same mapping.
