Lionel Sambuc 9fab85c2de Replacing timer_t by netbsd's timer_t
* Renamed struct timer to struct minix_timer
 * Renamed timer_t to minix_timer_t
 * Ensured all the code uses the minix_timer_t typedef
 * Removed ifdef around _BSD_TIMER_T
 * Removed include/timers.h and merged it into include/minix/timers.h
 * Resolved prototype conflict by renaming kernel's (re)set_timer
   to (re)set_kernel_timer.
