This patch adds a uapi header for rpl struct definition. The segments
data can be accessed over rpl_segaddr or rpl_segdata macros. In case of
compri and compre is zero the segment data is not compressed and can be
accessed by rpl_segaddr. In the other case the compressed data can be
accessed by rpl_segdata and interpreted as byte array.
