- This functionality it's just available when using api.h bindings. For exported functions current value ka_ping_interval is used. - Modified add_destination function to provide this new parameter. - Now we have one timer per destination, instead of multiple, so we don't need to iterate over all destinations. Timers are cleaned when destinations are removed.

With this code, you can have a different pinging timeout for each destination, instead of the fixed (default 30 seconds) one. This change is compatible (not breaking) with .cfg or kemi invocations, but it's breaking developers api. You can view, comment on, or merge this pull request online at:
