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.
