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.
