    core-util: Filter out not-a-numbers in pa_atod()
    
    We don't and probably never will have any pa_atod() callers that would
    require "NaN" to be accepted, so let's filter those out in pa_atod(),
    instead of requiring the callers to handle not-a-numbers appropriately
    (which they generally forget to do).
