event ratio dependant actions implementation

[Martin Pala]

Hi,

here is the implementation of the event ratio dependant actions.

It is now possible to specify how many events during how many cycles are 
needed to trigger the action. Both failed and passed actions may be 
restricted this way.

Example syntax:

 if failed ... [[X] [times] [within] Y cycles] then <action>
 else if passed [[for] Z cycles] then <action>


The part 'X times within Y cycles' is optional - when not used, monit 
will act on first event (equals to '1 times within 1 cycle'). It is also 
possible to specify just consecutive cycles count.

This behavior is generic and extends all testing rules. Backward 
compatibility is fully retained.

Example:
 check host foo.bar with address 192.168.1.1
   if failed port 80 for 5 times within 8 cycles then exec '/my/script'
   else if passed for 10 cycles then alert


If you agree, i will send it to cvs.
