kern_time syscall separation

[Matthew Dillon]

    Oh, I made some small modifications and a bug fix or three to the
    patch.

    I put the kern_* prototypes in sys/kern_syscall.h instead of sys/time.h.

    The switch in kern_clock_gettime() was missing 'break;' statements.

    The copyout() in sys_clock_gettime() was missing a semicolon.

    The switch in kern_clock_getres() was missing a 'break;' statment.

    Otherwise it looks ok.

    Generally speaking please try to test patches before submitting :-)
