  1. socketcan: support use of SO_TIMESTAMPING for hardware timestamps 

    The current implemenation of socketcan utilises SO_TIMESTAMPNS
which only offers system timestamps.

I've looked at how can-utils candump.c configures hardware
timestamping and implemented this in socketcan as a new option
'can_hardware_timestamps' which is disabled by default to avoid
any potential adverse impact on existing usage.

Additionally modify logger.py to provide an additional '-H' flag
in the same way that candump does in order to use this
functionality.
