    src/utils_threshold.c: Implement the “Hits” and “Hysteresis” config options.
    Hi all!
    Based on Mariusz's idea, i attach a patch for thresholds (no for
    filtering, yet) with basic hysteresis support adding the keyword
    Hysteresis to configuration file, for example:
      <Type "load">
         DataSource "midterm"
         WarningMax 1
         Hysteresis 0.3
      </Type "load">
    In this case the notification is raised when load (midterm datasource)
    is greater than 1, and came back to OKAY when lower than 0.7 (1 - 0.3).
    This is a proof of concept and I do not have a lot of time to test,
    please use this patch with caution. Furthermore, the code is really hard
    and dirty :)
    Best regards,
    P.S.: The patch also including hits support, so to compile you also
    require to apply hits-cache.patch and, obviously this patch is
    incompatible with hits-threshold.patch.

    src/utils_cache.c: Implement “uc_{get,set,inc}_hits”.
    I've attached a patch to add hit counter to thresholds, that is, each
    time when threhsold raised, then an internal hit counter is incremented,
    when the value of the counter raise a specific value setted in
    configuration, then the notification is generated and counter is reset.
    Here are an example of threshold configuration with hit conter:
      <Plugin load>
        <Type load>
           WarninMax 1
           Hits 3
    In this example the notification will be generated when load value is
    greater than 1 for 3 intervals.
    Here are two patches, the first one adds hit feature to the collectd
    cached and the second one use hits in thresholds,
    Of course comments and suggestions are welcome :)
