* infrun.c (can_use_displaced_stepping): Change type to
const char pointer.
(can_use_displaced_stepping_auto): New string.
(can_use_displaced_stepping_on): New string.
(can_use_displaced_stepping_off): New string.
(can_use_displaced_stepping_enum): New array.
(show_can_use_displaced_stepping): In auto mode, also show
the current effect of the option.
(use_displaced_stepping): Return non-zero if displaced
stepping is auto, and can be used with GDBARCH, and in
non-stop mode. Return non-zero if displaced stepping is on,
and can be used with GDBARCH. Return zero otherwise.
(_initialize_infrun): Make the "set displaced-stepping"
command an enum command. Change its class to class_run.
Place it in the top level set list. Extend help to describe
the auto mode.

* gdb.texinfo (displaced-stepping): Describe the auto mode
setting, and say it's the default. This is now a mainstream
setting instead of a maintenance setting.
