Initial code for log analysis

- we agreed to basically throw away the old log checker (as it is
  unmaintainable)
- now: provide list of analysis to do
  * all checkers in cls_log_analysis, can be unit tested (see also next
    commit)
  * looked up dynamically to simplify adding of new tests + config
  * configured with

      <analysis>
        <services>DESCRIPTION [DESCRIPTION...]</services>
        <service>DESCRIPTION</service>
        ...
      </analysis>

    where DESCRIPTION follows service=func[=options]:
    - service is name of service to check
    - func is function to call, which receives filename
    - option are arbitary options to pass to func
    <services> is whitespace delimited (so can take multiple service
    analysis definitions)
    <service> exists to allow service definitions with whitespace
    changes that would not work in <services>
- I initially planned to check return code, but most softmodems actually
  exit with non-zero return code, so this is still TODO
- Default analyzer (checking for assertions, ...) is always run if a
  service is listed
- checks for file size
- add unit tests
