Use explicit prototypes for struct dev_ops fields

* device/conf.h: Include <sys/types.h>, <mach/port.h>, <mach/vm_prot.h>.
Predefine struct io_req, io_req_t and io_return_t.
(dev_ops): Add explicit prototypes for d_open, d_close, d_read, d_write,
d_getstat, d_setstat, d_mmap, d_port_death.
(nulldev_open, nulldev_close, nulldev_read, nulldev_write,
nulldev_getstat, nulldev_setstat, nulldev_portdeath): Add prototypes.
(nomap): Fix prototype.
* device/dev_name.c (nulldev_open, nulldev_close, nulldev_read,
nulldev_write, nulldev_getstat, nulldev_setstat, nulldev_portdeath): New
functions.
(nomap): Fix prototype.
* device/ds_routines.c (dev_close): Pass 0 as flag parameter.
* device/kmsg.c (kmsgclose): Drop return value.
* device/kmsg.h (kmsgclose): Fix prototype.
* i386/i386at/com.c (comopen): Fix prototype.
(comclose): Fix prototype, drop return value.
(comread, comwrite): Fix prototype.
* i386/i386at/com.h (comopen, comclose, comread, comwrite): Fix
prototype.
* i386/i386at/conf.c (dev_ops): Use nulldev_open, nulldev_close,
nulldev_read, nulldev_write, nulldev_getstat, nulldev_setstat,
nulldev_portdeath where appropriate.
* i386/i386at/kd.c (kdclose, kdread, kdwrite, kdmmap): Fix prototype.
* i386/i386at/kd.h (kdclose, kdread, kdwrite, kdmmap): Likewise.
* i386/i386at/kd_event.c (kbdopen): Likewise.
* i386/i386at/kd_event.h (kbdopen): Likewise.
* i386/i386at/kd_mouse.c (mouseopen): Likewise.
* i386/i386at/kd_mouse.h (mouseopen): Likewise.
* i386/i386at/lpr.c (lpropen, lprclose, lprread, lprwrite): Likewise.
* i386/i386at/lpr.h (lpropen, lprclose, lprread, lprwrite): Likewise.
* i386/i386at/mem.c (memmmap): Likewise.
* i386/i386at/mem.h (memmmap): Likewise.
* i386/i386at/model_dep.c (timemmap): Likewise.
* i386/i386at/model_dep.h (timemmap): Likewise.
* kern/mach_clock.c (timeopen, timeclose): Likewise.
* kern/mach_clock.h: Include <sys/types.h>, predefine struct io_req and
io_req_t.
(timeopen, timeclose): Fix prototype.
