    Add the mach_print debugging system call
    
    The purpose of this system call is to help debugging in situations where
    it's desirable to bypass the mach_msg call entirely.
    
    * include/mach/syscall_sw.h (mach_print): Generate system call code.
    * kern/syscall_subr.c: Include <kern/printf.h>.
    [MACH_KDB] (mach_print): New function.
    * kern/syscall_subr.h (mach_print): New prototype.
    * kern/syscall_sw.c [MACH_KDB] (mach_trap_table): Declare mach_print
    system call.
