Replace tui_restore_gdbout with scoped_restore
This patch replaces tui_restore_gdbout (a cleaup function) with a use
of scoped_restore. This one is broken out into its own patch because
it might slightly change the behavior of gdb: it saves and restores
pagination_enabled, whereas the tui_restore_gdbout unconditionally set
pagination_enabled to 1; and I think this warrants closer review.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* tui/tui-regs.c (tui_restore_gdbout): Remove.
(tui_register_format): Use scoped_restore.
