Improvements and changes to integrate bsddialog(1) with scripts in BASE. Overview: * New options. --and-widget, --keep-tite, --calendar. * Change output format. Menus and --print-maxsize. * Redefine sizing. Fixed rows, cols and menurows became at the most. * Add DIAGNOSTICS. Error messages for bad arguments and options. * Add keys. Space for --menu, fast keys for --msgbox and --yesno. * Text. Change default text modification, add --cr-wrap. See /usr/src/contrib/bsddialog/CHANGELOG '2022-09-24 Version 0.4' for more detailed information. Merge commit '9f24fda5a8e7ab8243e71473c7e2dc98b4877e64'
