Fix kernel testing and make it target specific.

Note that this change is in R11, as it should be enabled asap.

This CL fixes kernel messages autotest by introducing
platform specific lists of the kernel warning and error
messages expected on startup.

Some of these messages are harmless, and some require
investigation/fixing. This CL just cleans up the lists of
accepted error/warning messages and provides for platform
specific extensions.

The recently introduced crossystem utility is the way to
deteremine system specific parameters in a platform
independent way. This CL introduces a class to represent
the crossystem reported information in a programmatic way.

The crossystem output of form 'name = value' is parsed and
placed in a dictionary.  The __getatttr__() method override
allows to use object_instance.name() to access the value of
the parameter 'name'.

Instead of using exact warning/error messages' list the
regexes of messages are allowed, which is handy in
situations when messages are run time specific (use hash
values or addresses, etc.)
