On platforms where hardware timers are available, test these in each combination of hard/soft and one-shot/periodic in the same way as for software timers. Where a platform supports both software (id = -1) and hardware (id >= 0) timers, the behaviour of both is now checked. For now, esp8266 is the only platform that supports hardware timers and both hard and soft callbacks. Signed-off-by: Chris Webb <chris@arachsys.com>
