* infrun.c (set/show scheduler-locking) New command.  Set a
          mode bit that will control how GDB attempts to control thread
          scheduling for step, continue, etc.  (resume): make use of
          the schedule-locking mode.
        * target.h (struct target_ops): new field to_has_thread_control.
        * sol-thread.c: initialize target_ops to_has_thread_control.
        * procfs.c: ditto.
        * target.c: ditto.
        * m3-nat.c: ditto.
