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.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Somewhere along the way, multiple targets started working and nobody
noticed.

Add another hateful global to libdialog (what the heck, there are already
so many). For now, the only extended attribute implemented is NO ECHO,
useful for things like passwords. See TESTS/input2.c for an example.
This should go into 2.2.

Make this properly respect obj dirs.

Create individual tests for each dialog feature.

o Add some test code.
