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)
Access permission bits are required eventually but currently are
not a critical concern and yet they complicate configuration. For
sake of simplicity they are removed to be added later on when
absolutely needed.
CML boolean type compiles into #define and #undefs.
This is not useful for capabilities since a value of 0 or 1 can be
used automatically for setting or unsetting bits in permission words.
Meanwhile using an integer type with 0 - 1 range has a worse usability
experience than the boolean Y, N.
Also moved parsing of container.template.cml to newer Python argument
parsing format.
This parameter does not significantly pose a restriction on configuration.
It can be adjusted depending on phys_offset. Therefore we don't maintain it.
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.
Deriving symbols didn't work because cml2 silently ignored symbols
that were declared previously for derivations. Not pre-declaring derived
symbols have solved the problem.
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
