The attached update implements various improvements and bugfixes for the
current wireshark dissector:

- New Config option to configure the sequence of frames using UDP
- an Info will be added, if the SCM UDID is not configured or if it is wrongly
configured, so that the user can act on it.
- SCM UDID will only be printed if configured correctly, if not a warning will
be added to inform, that the first byte for the UDID will be assumed to be 00
- UDP dissection can enforce the number of sub-package the dissection should
assume
- SSDO: isRequest is determined by it's field not by the message id
- SSDO: Unused code for SNMT Reset Guarding SCM has been removed
- SNMT: error_group and error_code for SN_FAIL have not been dissected
correctly
- Sercos III: bug != instead of ==, is fixed
- dissect_opensafety_udp renamed to dissect_opensafety_udpdata, because of
future dissector called opensafety_udp which will handle transport of
openSAFETY data over UDP
- dissect_opensafety_udpdata enhanced to determine the index of the given frame
in the package. Needed for correct assembly of COL_INFO
- Added heuristic dissector hook for opensafety_udp dissector. The dissector
will be submitted to this list at a future point

- Enhanced description of the dissector to reflect it's capabilities
- Reworked the description for the config options to be more understandable


Fuzz Tests and randpkt tests have been performed, the patch passed with flying
colors ;-)

regards,
Roland
