* 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.
* remote.c: ditto.
* hpux-thread.c: ditto.
