Add can-dev-mapping-helperjellyfish_9.99.3jellyfish/9.99.39.99.3
Changes: - Add a can-dev-mapping-helper.sh script and systemd unit to drive it, the script checks if the CAN devices specified in the low-can configuration file /etc/dev-mapping.conf exist, and if not brings up corresponding virtual CAN devices. - Add a systemd over-ride conf file for agl-service-can-low-level that makes can-dev-mapping-helper a dependency. This should ensure that the low-can binding always starts even if there are no physical CAN hardware devices. - Added a Before statement to sllin-demo.service to ensure that it will run before can-dev-mapping-helper and ensure that lin_config can create sllin0 correctly. - Removed the sllin-demo-virtual systemd unit, as it will no longer be required with can-dev-mapping-helper. - Updated the /var/run paths in sllin-demo.service and associated start_lin_demo.sh script to quiet systemd warnings about /var/run usage.
