xTaskGetTaskHandle() changed to xTaskGetHandle().

Tidy up CEC1302 demo.
Ensure bit 0 of the task address is clear when setting up stack of initial Cortex-M3/4/7 stacks (for strict compliance, although not practically necessary).
vTaskGetTaskInfo() changed to vTaskGetInfo() - with a macro added for backward compatibility.
