nano_lifo: Simplify nano_xxx_lifo_get() API family

Browse source 
Changes the nanokernel LIFO API so that the timeout parameter must be
specified when invoking nano_isr_lifo_get(), nano_fiber_lifo_get(),
nano_task_lifo_get() and nano_lifo_get().

This obsoletes the following APIs:
	nano_fiber_lifo_get_wait()
	nano_fiber_lifo_get_wait_timeout()
	nano_task_lifo_get_wait()
	nano_task_lifo_get_wait_timeout()
	nano_lifo_get_wait()
	nano_lifo_get_wait_timeout()

* 1) The enablement of interrupts and entering a low-power mode needs to be
* atomic, i.e. there should be no period of time where interrupts are
