splitting device.h

[David Young <dyoung%pobox.com@localhost>]

I would like to break the circular dependency between <sys/pmf.h> and
<sys/device.h> by moving basic declarations out of <sys/device.h> and
into a new header file, <sys/device_if.h>.  Ok?  Here is what I have so
far:

#ifndef _SYS_DEVICE_IF_H
#define _SYS_DEVICE_IF_H

struct device;
typedef struct device *device_t;

#ifdef _KERNEL
struct device_lock;

typedef struct device_lock *device_lock_t;
#endif

#endif  /* _SYS_DEVICE_IF_H */
