[PATCH 2/5] autoparam: script

[Magnus Damm]

The quick ruby hack that generates text from the section data. The script
should probably be rewritten in some other languare to minimize dependencies.
Parameters without types are the result of MODULE_PARM_DESC typos or the use of
MODULE_PARM() instead of module_param() and are treated as errors.
