Use Mach native error codes instead of POSIX errno E* ones
* device/errno.h: Remove file. * Makefrag.am (libkernel_a_SOURCES): Remove `device/errno.h'. * i386/i386at/com.c: Include <device/device_types.h> instead of <device/errno.h>. (comopen): Replace ENXIO with D_NO_SUCH_DEVICE. * i386/i386at/kd_event.c: Include <device/device_types.h> instead of <device/errno.h>. * i386/i386at/kd_mouse.c: Likewise. (mouseopen): Replace ENODEV with D_NO_SUCH_DEVICE and EBUSY with D_ALREADY_OPEN. * i386/i386at/lpr.c: Include <device/device_types.h> instead of <device/errno.h>. (lpropen): Replace ENXIO with D_NO_SUCH_DEVICE and EBUSY with D_ALREADY_OPEN.
