Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Update dialog to version 20100428. This changes the license under which
dialog is distributed from GPLv2 to LGPLv2 and introduces a number of new
features and a new and better libdialog API. The existing libdialog will
be kept temporarily as libodialog for compatibility purposes until sade,
sysinstall and tzsetup have been either updated or replaced.

__FreeBSD_version is now 900030.

Test data before using it.

Of course, libdialog is still chock-full of similar bugs, but it's been
multiple years and no one has any better suggestions so the bugs will just
be dealt with case-by-case.

PR: 28221

Use __FBSDID over rcsid[].

Improve the interface provided by libdialog. Move a cursor around over
the components and trigger actions based on its position. This reduces
the need to remember the functions of various keys, and makes the
interface more consistant across library.

*Really* make space accelerators work; no wonder Brian McGovern was
confused! I fat-fingered the first commit.

Prevent spaces from being interpreted as accelerators.

Use braces to avoid potentially ambiguous else clause.
main's return type is int not void.

Go on one of my periodic rampages through this code, trying to make
it DTRT. In the process, discover the usual 10-15 evil bogons which
have been lurking in it for years. This closes, for one thing, the
recent report Mike Smith made about nested checklist menus returning
with the scrolling region messed up.

Allow emacs-style next/prev characters as well as arrow keys so that
I can offer this as a consistent feature.

1. Remove some ancient bogons from when I initially added dialogMenuItem
support.
2. Have message boxes say "Continue" instead of "Exit"

Fix a couple of whoopers which somehow went undetected until now.

Add missing dialog_clear() calls.

Fix the OK/Cancel accellerator bogon I introduced a few days back.

Fix what I just broke with DITEM_LEAVE_MENU

More custom hackery to deal with issues discovered in sysinstall.

Allow some post-fire actions to be combined in ways that weren't
possible before.

Make the DITEM_RECREATE option work properly.

Remove a long-standing window leak I just noticed.

Remove the special-case behavior for fire actions that return
DITEM_FAILURE - formerly they would simply act as an implicit "continue",
but this is wrong. If you want this behavior, you should now return
with the DITEM_CONTINUE flag set.

Also make the semantics of DITEM_RESTORE quite a bit different - rather
than restore the screen back to pre-menu state, we restore the menu
itself. This is more correct for a variety of reasons when dealing with
nested menus (whoops!).

More changes to attempt to make this whole new dialog scheme more
robust. The new "fire" actions, while affording signficantly more
interactivity to libdialog, come at a cost - if the fire action trashes
the screen then you're not going to be in Kansas anymore when you
come back to the menu and there had better be considerable extra
smarts in place for coping with such a situation. These changes are my
attempt to do just that.

Remove some of the grot I added to try and save/restore screen contents.
This shouldn't be done here, it should be done in the client as needed.

Save screen before calling any fire() callbacks - you never know what
they might do to the screen.

Refresh dialogs if a callback action fails.

Next round of changes - make dialog boxes drawable at arbitrary X,Y locations
and add selection traversal callbacks so context-sensitive behavior can
even be implemented for individual menu items. These work around the two
largest issues holding me back with some of my sysinstall changes.

Add changes to:
o Support a new, fully backwards-compatible API for controling
individual items in dialog menus.
o Write a man page.
o Add some test code.

Remove trailing whitespace.

Saved scroll fixed.
