Fix warnings

* device/chario.c (ttypush): Set parameter type to void * instead of
struct tty *, and implicitly cast the former into the latter instead.
* i386/i386at/com.c: Include <kern/mach_clock.h>.
(timeout, ttrstrt): Remove declarations.
(comtimer): Add unused void * parameter.
(comopen): Pass NULL to comtimer function.
* i386/i386at/kd.h (kd_belloff): Add unused void * parameter.
* i386/i386at/kd.c (timeout): Remove declaration.
(kd_belloff): Add unused void * parameter.
(feep, kdsetbell): Pass NULL to kd_belloff function.
* i386/i386at/lpr.c: Include <mach_clock.h>.
(timeout, ttrstrt): Remove declarations.
* kern/mach_clock.c (softclock, timeout, untimeout): Set parameter
type of fcn function pointer to void * instead of char *. Set type
of param to void * instead of char *.
* kern/mach_clock.h (timer_elt): Set parameter type of fcn member
to void * instead of char *. Set time of param member to void * instead
of char *.
(timeout): Set parameter type of fcn function pointer parameter to void
* instead of char *.
(untimeout): Likewise, set type of param parameter to void * instead of
char *.
* kern/sched_prim.c (sched_init): Remove cast of recompute_priorities.
Replace (char *)0 with NULL.
(thread_timeout): Set parameter type to void * instead of thread_t, and
implicitly cast the former into the latter instead.
(thread_timeout_setup): Remove cast of thread_timeout, cast
thread_depress_timeout into (void (*) (void*)). Remove cast of thread.
