Subject: Console declaration cleanup

* device/cons.h: Add multiple inclusion _DEVICE_CONS_H macro protector.
(struct consdev): Add function members prototypes.
* i386/i386/xen.h: Include <mach/xen.h>.
* i386/i386at/com.c (comcnprobe, comcninit, comcngetc, comcnputc): Move
prototypes...
* i386/i386at/com.h: ... here.  Include <device/cons.h>.
* i386/i386at/cons_conf.c [MACH_HYP]: Include <xen/console.h>.
[!MACH_HYP]: Include "kd.h".
[!MACH_HYP && NCOM > 0]: Include "com.h".
(hypcnprobe, hypcninit, hypcngetc, hypcnputc, kdcnprobe, kdcninit, kdcngetc,
kdcnputc comcnprobe, comcninit, comcngetc, comcnputc): Remove prototypes.
* i386/i386at/kd.c (kdcnputc): Make it return int, -1 on error, 0 on
success.
(kdcnprobe, kdcninit, kdcngetc, kdcnputc): Move prototypes...
* i386/i386at/kd.h: ... here.  Include <device/cons.h>.
* xen/console.c (hypcnprobe): Remove unused `my_console' local variable.
* xen/console.h: Include <device/cons.h>
(hypcnputc, hypcngetc, hypcnprobe, hypcninit): Add prototypes.
