mach: Add __mach_setup_thread_call ()
This is just like mach_setup_thread (), but it's suitable for making the thread call a function correctly, as opposed to explicitly setting the thread's stack and instruction pointers to the given values. Internally, it uses MACHINE_THREAD_STATE_SETUP_CALL. Unlike mach_setup_thread (), which is exported via mach.h for the benefit of the Hurd exec server, __mach_setup_thread_call () is private to glibc for the time being.
