Log message:
First stab at making ptrace(2) usable for debugging multi-threaded programs.
It implements a full-stop model where all threads are stopped before handing
over control to the debugger. Events are reported as before through wait(2);
you will have to call ptrace(PT_GET_PROCESS_STATE, ...) to find out which
thread hit the event. Since this changes the size of struct ptrace_state,
you will have to recompile gdb.
