I could not find any, but the search was not amazingly thorough. The 
libdialog we had was entirely peculiar to FreeBSD, basically only for 
the use of sysinstall. Most external dialog-using things use dialog(1),
which is compatible, and those that don't require the newer version I 
propose to import.

Since I plan to immediately replace dialog(1), and libodialog is 
immediately deprecated, renaming the old library seemed to simplify 
things substantially. Having libdialog under its standard name reducing 
the need for patching it, patching dependent ports, and confusion.
