------------
 
this test shows a set of 5 tasks (+main+dummy+keyboard driver).
The first 4 tasks are scheduled by a EDFSTAR Module, whereas the
fifth one is a standard traditional EDF task. The 4 tasks uses a
budget of 10000/100000.
if edfstar.c is compiled with edfstar_printf3 active, a couple
(dline, curtime) is showed (in ms).
if cbsstar.c is compiled with cbsstar_printf3 active, the budget
replenishments are showed.
