Add IPC functions that allow user to manipulate with memory advice.
* include/mach/mach_types.defs (vm_advice_t): New type definition.
* include/mach/mach.defs (vm_advice): New RPC definition.
(memory_object_set_advice): Likewise.
(memory_object_get_advice): Likewise.
* kern/ipc_mig.c (syscall_vm_advice): New function. This is optimization
function for RPC that is processed by kernel.
* kern/syscall_sw.c (syscall_vm_advice): Add function prototype.
(mach_trap_table): Add syscall_vm_advice to trap table.
* vm/memory_object.c (memory_object_set_advice): New function. Sets memory
advice for memory object.
(memory_object_get_advice): New function. Returns memory advice of memory
object.
* vm/vm_user.c (vm_advice): New function. Wrapper for vm_map_advice.
* vm/vm_map.h (vm_map_advice): Add function prototype.
* vm/vm_map.c (vm_map_advice): New function. Sets memory advice for memory
