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.
