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
