Test container is planned to test codezero microkernel extensively.
With these changes, everything is there to develop a full-featured test suite.
It also exemplifies how a new container type can be added to the system.
(cherry picked from commit f21fa53df421bfc8eeeaa096c89b98beed436c60)
Container rules are too many and repetitive for each container. With this
change, the cml file is autogenerated from a container template cml and
the architecture cml, e.g. arm.cml. -c option determines the number of
containers. See build.py -h for more.
Created a config directory for configuration files.
Moved all absolute path variables to a projpaths.py file
All scripts can now universally learn absolute paths via projpaths.py
Moved the config_symbols class to the configuration.py file.
Moved libs to loader since they are only referred by the loader
