    canopen: Enhanced SDO decoding

    * Move sdo dissection to separate function

      Added dissect_sdo() function to handle the more complex SDO dissection.

    * SDO command specifier decoding

      Decoding of both client and server command specifier for SDO transfers
      according to CiA 301 Chaper 7.2.4.3.

      Note: Fully decoding block transfer frames is more complex and not
supported
      yet.

    * basic SDO abort code decoding

      SDO abort codes as specified in CiA 301 Chapter 7.2.4.3.17 (Table 22).

    * Basic value ranges for object dict index parameter

      Object dict ranges as specified in CiA 301 7.4.1 (Table 41)

    * cs-based multiplexer and data decoding

      A data width of 4 byte is valid only for expedited transfer and a
      multiplex value is present only in initialisation messages.

      This patch now handles also normal sdo segment data.

      Reference: CiA 301, Chapter 7.2.4.3.3 and 7.2.4.3.6
