+function from TASK_ROM_MFTAB inside MFTAB by checking
+ fct pointer amd the two parameters param1 and param2.
+If test is true (i.e parameters and function pointer
+ are used for the current task executuion ) , a clean
+is done by setfct pointer to NULL
+in order to erase this function of MFTAB .The clean up
+is applied until the last frame used by current task
+(number of frames used by a task is defined by size
+variable).
+When clean up is done , reset active frame if current
+frame is the last frame of MFTAB.
+This function allow to pipeline fast signaling blocks
+with non fast signaling blocks without lose blocks.
