Unconditionally use the device driver multiplexing. Suggested by
Gianluca Guida <glguida@gmail.com>.
* i386/i386at/dev_hdr.h: Merge into `device/dev_hdr.h' and remove.
* i386/i386at/device_emul.h: Rename to `device/device_emul.h'. Adapt
all users.
* i386/i386at/i386at_ds_routines.c: Merge into `device/ds_routines.c'
and remove.
* i386/linux/dev/include/linux_emul.h: Remove file.
* Makefrag.am (libkernel_a_SOURCES): Add `device/device_emul.h'.
* i386/Makefrag.am (libkernel_a_SOURCES): Remove
`i386/i386at/dev_hdr.h', `i386/i386at/device_emul.h' and
`i386/i386at/i386at_ds_routines.c'.
* i386/linux/Makefrag.am (liblinux_a_SOURCES): Remove
`i386/linux/dev/include/linux_emul.h'.
* dev/dev_hdr.h: Adapt all users of `i386' as if it were always
defined.
* device/dev_lookup.c: Likewise.
* device/ds_routines.c: Likewise.
* device/device_init.c (ds_init): Rename to `mach_device_init'.
* device/ds_routines.c (ds_init): Likewise.
(ds_trap_init): Rename to `mach_device_trap_init'.
(mach_device_trap_init): Make it `static'.
* linux/dev/glue/block.c: Don't include <linux_emul.h>, but instead
include <device/device_emul.h> and <i386at/disk.h>.
* linux/dev/glue/net.c: Don't include <linux_emul.h>, but instead
include <device/device_emul.h>.
* linux/pcmcia-cs/glue/ds.c: Likewise.
