kuksa-dbc-feeder: add recipe and dependencies
Add a kuksa-dbc-feeder recipe to build the sample CAN feeder for the KUKSA.val Vehicle Information Service (VIS) server and add it to the agl-demo-platform image by adding it to packagegroup-agl-ivi-services. Local patches are applied to enable building with OpenEmbedded, make installation into standard Linux FHS locations feasible, and improve usability on target with respect to logging and error handling. These will be discussed with upstream to hopefully get them integrated. Additional changes: - Add a recipe for the required kuksa-viss-client Python module included with the KUKSA.val source tree. The module is also available via pypi.org, but keeping all the pieces in lockstep for now seems better, so it is built out of a clone of the kuksa.val repo using the same SRCREV as the server and kuksa-dbc-feeder. - Add new recipes for required Python modules: python3-argparse-addons, python3-can-j1939, python3-py-expression-eval, python3-setuptools-git-versioning These will be upstreamed to meta-python as time permits. - Add bbappend for python3-cantools to add a missing runtime dependencies discovered during testing. This will be addressed upstream in meta-python as time permits. - Add minimal DBC file and mapping configuration. At present the agl-vcar.dbc file only contains the minimum message definitions known to be required for the AGL demo platform, namely vehicle and engine speeds and the steering wheel events. - Add can-dev-helper recipe to install a systemd unit and script to ensure a CAN interface is available for testing. This is a tweaked version of what was previously used with agl-service-can-low-level.

+Subject: [PATCH] dbc2val: add installation mechanism
+
+Add setup.py and setup.cfg to allow installing the dbc2val module
+and dbcfeeder.py in a way suitable for packaging. Some of the
+imports in the scripts have been tweaked to enable running against
+an installed copy of dbc2val.

+Date: Thu, 12 May 2022 17:39:56 +0200
+Subject: [PATCH] dbc2val: usability improvements
+
+Changes:
+- Tweaked default configuration file search path to better match
+ Linux FHS and kuksa-val-server. First look for a config.ini in
+ /etc/kuksa-dbc-feeder, then /etc/dbc_feeder.ini.
+- Added a command-line option to specify configuration file, this
+ should allow running two instances against different interfaces.
+- Added verbosity command-line option and made several messages
+ verbose mode only to avoid log spamming.
+- Added '-u' option to python invocation to disable output buffering.
+ The intent is to make logging immediate, otherwise errors may not
+ get logged for some time (or at all).
+- Add catching of exceptions around CAN device opening so that the
+ script can exit cleanly with an error message if the device is
+ not available.
+
+Upstream-Status: pending
