Changes:
* Implement patty_timer type to store both a struct timeval and a
bitfield for indicating timer state; currently, this only holds
the PATTY_TIMER_RUNNING flag to indicate whether a timer has been
stopped (irrespective of its "expired" status)
* Remove 'target' argument from patty_timer_start(); instead, rely
on select() polling every 1s to cause events to trigger at a
regular interval
* Make patty_timer_expired() return false if PATTY_TIMER_RUNNING is
not set
* Implement patty_timer_stop() to clear the PATTY_TIMER_RUNNING flag
of a timer
* Make patty_timer_clear() set all fields to zero, including
clearing the PATTY_TIMER_RUNNING flag
